SECTION 1 -- GENERAL INFORMATION AND SAFETY 1--16 FUEL SAVING TIPS FOR OPTIMUM OUTPUT Proper maintenance of Tractor reduces fuel consumption to a greater extent. 1. Store fuel in properly cleaned, rust and contamination free containers. 2. Always fill the tank at the end of each day to reduceovernight condensation ofmoisture in the air, in turn to avoid damage to the fuel system. 3. Fuel filters should be replaced as per recommended time schedule as the filtering capacity is not retained after this specified time. It may allow harmful contamination and damage the fuel injection system. Follow the service schedule for draining the water from the filters and cleaning the feed pump filter. 4. Always use genuine fuel filters available from your Authorised Dealers. 5. Stop diesel leakage, if any, immediately. 6. Dirt particles entering the engine causes early wear of liners and piston rings, resulting in loss of power, engine oil & fuel consumption. Clean the pre--cleaner bowl daily and change the air cleaner oil as mentioned in service schedule. Ensure that there is no leakage through hoses and the air cleaner bowl seal is in good condition, keep hose clamps tight. 7. Check the Radiator coolant level daily and top--up with clean water only. Radiator fins should always be kept clean. Should it be necessary to replace radiator cap, use only genuine cap of the specified pressure . Never try to remove the thermostat. Check and adjust fan belt tension regularly. Ignoring these, will result in engine over heating and heavy diesel consumption. 8. Follow the running--in procedure given in this manual for optimum performance of your tractor. 9. Do not run the engine in idle condition for more than twominutes. It may result inwastage of fuel. 10. Do not rest your foot on clutch pedal, as this will cause clutch slippage, loss of engine power and increased fuel consumption. Maintain the specified cluctch pedal free play. 11. Always drive the tractor in proper gear. 12. Use a lower gear while driving down a slope and use brakes sparingly. 13. Maintain proper tyre pressures for field work as well as for roadwork. Refer the tyre pressure chart given in this manual. Worn out tyres causes wheel slippage andwaste fuel. Re--tread or replace the tyres if they are badly worn out. Adhere to tyre ballasting as andwhen required to reduce wheel slippage and fuel consumption. 14. Always use matching implements to cut down the diesel wastage. Implements should be maintained in good condition, as usage of worn out implements will waste fuel. 15. Always plough lengthwiseand plan your field run to reduce fuel consumption. Adjust the wheel track to suit the implement and avoid overlap when working in the field. 16. When using a PTO driven equipment, operate the engine at the recommended speed to reduce fuel consumption.

BEFORE OPERATING CAUTION Before driving or operating the tractor, study the safety precautions in Section 1 of this manual. Read this section carefully for a thorough understanding of operational requirements. Even if you operate other tractors, you should thoroughly read this section of the manual and ensure that you are familiar with the location and function of all the controls of this tractor. Do not start the engine or attempt to drive or operate the tractor until you are fully accustomed with all controls. It is too late to learn once the tractor is moving. If in doubt about any aspect of operation of tractor, consult your Authorised Dealer. See Section 4 for lubrication and maintenance requirements. Tractor specifications will be found in Section 7. Subject Page Running--in Procedure 3--2 Pre--Operation Checks 3--2 Starting the Tractor 3--4 Stopping the Engine 3--6 Turbo Power 3--7 Power Take--Off 3--8 Three Point Linkage 3--13 Towing Attachments 3--19 Hydraulic System 3--21 Track Adjustments 3--27 Tractor Ballasting 3--32 Tyre Inflation 3--35 SECTION 3 -- FIELD OPERATION 3--2 RUNNING- IN PROCEDURE Your tractor will provide longand dependable service if given proper care during the first 50--hours running--in period and if serviced at the recommended intervals. Avoid overloading the engine. Operating in a high gear under heavy load may cause engine overloading. Overloading occurs when the engine will not respond to a throttle increase. Do not operate the engine without a load. This can be as harmful to the engine as overloading. Ensure that the engine is subjected to heavy as well as light loads during the running--in period. Use the lower gears when pulling heavy loads and avoid continuous operation at constant engine speeds. Operating the tractor in a low gear with light load and high engine speed will waste fuel. You will save fuel and minimise engine wear by selecting the correct gears for particular operation. Check the instruments frequently and keep the radiator and various oil reservoirs filled to the recommended levels. PRE-OPERATION CHECKS Before operating the tractor, ensure that you are thoroughly familiar with the location and operation of the controls. Perform daily lubrication andmaintenance operation in accordance with Section 4. After completing the daily maintenance operations, perform a walk around visual inspection of the tractor. Pay particular attention and check the following items: i. Fan belt for cracks. ii. Engine area for accumulation of debris. ii. Hoses, lines and fittings for leaks and damages. iv. Tyres for damage. v. Hardware for looseness. vi. Leakage at joints. Make any necessary repairs before using the tractor. SECTION 3 -- FIELD OPERATION 3--5 STARTING THE ENGINE Before starting the engine, always carry out the following procedure: • Get into the tractor from left hand side only. • Sit in the driver seat. • Ensure that both gearshift levers are in neutral. • Ensure the P.T.O. is disengaged. • Depress the clutch pedal. IMPORTANT: Never push or tow the tractor to start the engine. Doing so may overstress the drive train. NOTE: Neutral start switch prevent operation of the starting motor unless the gear levers are in the neutral position. Figure 2 A three--position key--start switch is installed. The key--start switch positions are as follows: Position 1 Electrical equipment Off Position 2 Accessories on (Head lamp, Instrument cluster, horn and gauges.brake lights, turn signal) Position 3 Starter motor engaged 2 3 1 2 Starting in warm weather or when the engine is hot • Bring the hand throttle lever to the halfway position, ensure both gear levers are in neutral, depress the clutch and turn the key--start switch fully clockwise to position (3) to operate the starting motor. Crank the engine and do not operate the starter motor for more than 10 seconds. When the engine starts, allow the key to return to positon (2). • Return the hand throttle lever to the idle position and check that all warning lights are off and gauge readings normal. SECTION 3 -- FIELD OPERATION 3--6 Starting in cold weather CAUTION When starting the tractor after long periods, avoid immediate use of hydraulics. It is necessary to allow time for enough lubrication of all moving parts before subjecting them to work loads, particularly if outdoor temperatures approaches zero degree Celcius (0C). Run the engine at 1300 to 1500 rpm for about 5 minutes so that to bring the rear drive oil up to normal operating temperature. • Before starting the tractor after a long period or whenstarting in cold climates, prime the fuel feed pump for about twenty times. • Bring the hand throttle lever fully down and turn the key--start to position (4) to activate the starter motor. Crank the engine until it starts but do not operate the starting motor for more than 10 seconds. When the engine starts, allow the key to return to position (3). • If the engine fails to start repeat the above procedureoperating the startermotor for up to10 seconds. If the engine still fails to start, repeat the whole procedure after 4--5 minutes. • When the engine starts, return the hand throttle lever to the idle position and check that all warning lights are off and gauge readings normal. • Do not remove thermostat as this could cause engine problems. • Do not cover the engine or radiator during cold weather. STOPPING THE ENGINE Figure 3 Tostop the engine, carry out the followingprocedure: • Remain in the driver seat. • Bring the hand throttle lever to the idle position. • Ensure that both gearshift levers are in neutral and that the P.T.O. lever is in disengaged position. • Apply the parking brake. • Move the hydraulic lift Position control lever fully forward to lower all hydraulic equipment to the ground. • Bring the key start switch to position 1. 2 3 1 3 WARNING Check the area under the equipment to ensure that no injury or damage will be caused when equipment is lowered. SECTION 3 -- FIELD OPERATION 3--7 TT65 TURBO POWER Figure 4 TT65 is fitted with turbo charger (1) figure 4 it helps, pushing the intake air, so better volumetic efficiency & thus full utilization of fuel that results into more torque & power. TURBO CHARGER LDA Figure 5 IMPORTANT:TheLDA is adjustedand set by bosch. If LDA require any type of adjustment the injection pump with LDA must be brought to an authorised dealer. Important Tips for Turbo Charger 1. Before accelerating on starting and before shutting down TT65 tractor model, let the engine idle at about 700 RPM for 30 seconds to ensure that the Turbo Charger is fully lubricated. 2. The LDA asmarked (1) in the figure 6 is adjusted and set by Bosch. If LDA requires any type of adjustments, the fuel injection pump with LDA must be brought to authorised Bosch specialist. 3. When tractor is not in use, cover the exhaust outlet to prevent theTurboCharger rotating in the wind, to avoid damage to bearings, as shaft bearing will not be lubricated. 4. Always get your tractor serviced from authorised dealer so as to use only genuine engine oil and filter. Contaminated oil can harm both your engine and Turbo. 5. To get maximum life of Turbo Charger, recommended service intervals should be adhered. 6. Ensure no foreign particle externally damage or enter in the system. 1 4 1 5 WARNING Do not alter any FIP, LDA setting. Always bring FIP to authorised Bosch Dealer. Violation of this will make warranty Invalid. SECTION 3 -- FIELD OPERATION 3--10 P.T.O.

Three hole rocker Three holes (2) are provided for attachment of the top link. Use the centre or lower holes, while using Draft or Position control. With the top link in the lower hole the hydraulic system is more sensitive to draft signals than in the middle hole. IMPORTANT: During transport, top link should be in upper hole. 1 2 20 Adjustable Check Chains Figure 21 External check chains are fitted as standard fitment andmay be adjusted to control the lateral movement of equipment connected to the three--point linkage. To adjust, rotate the Turn Buckle(1) clockwise to tighten and anti clockwise to slacken the chain. Check chains should be adjusted with implement raised. Adjust the check chains to ensure that the lower links do not foul the rear tyres and that no part of the implement can touch the fenders. 1 21 SECTION 3 -- FIELD OPERATION 3--17 Auxiliary Hydraulic Valve (If fitted) Figure 22 An auxiliary hydraulic valve uses oil from the hydraulic system to actuate single or double--acting cylinders. The valves are operated by lever (1) which is located in the right of operated seat. Each control valve is provided with two quick--attached 0.5 inch female couplings (2) suitable for connection to the quick--attach male couplings of the implement IMPORTANT:When not in use, couplings should be protected by means of the plastic cap provided. -- Stopping the engine. -- Lowering any implements connected to lift. -- Thoroughly cleaning couplings. Auxiliary hydraulic valves can act as both, single or double acting. CAUTION When released, all levers will return automatically to neutral position, locking implement in the set position. 1 2 22 SECTION 3 -- FIELD OPERATION 3--20 Rear Tow Hook NOTE: Rear tow hook is not a standard fitment. It is available as an accessory. Figure 28 & 29 Rear tow hook is suitable for towing all types of trailers including two wheeled trailers. It can be fitted to the tractor in two positions (A & B) as shown in Figure 28. A total of eight different heights of the hitch point above theground (four in eachposition) ranging from 505mm to 690mm (NH TT55 model) & 533mm to 720mm (NHTT75 model) canbeachievedby raising or lowering the tow hook, within the bracket. Figure 29. WARNING Do not pull from the lower links. Always use the drawbar or pick--up hitch lower position for pull--type work, otherwise the tractor may overturn rearwards CAUTION Hitching point above the center of rear axle is dangerous. It may cause front lifting of tractor & lead to accident. A B 28 29 SECTION 3 -- FIELD OPERATION 3--21 HYDRAULIC SYSTEM This is a live hydraulic system, where gear type hydraulic pump is mounted directly to timing case. transmission lubrication oil is used also as hydraulic oil. This system describedheremechanically senses changes in the draft loading via the top link of the three point linkage. The system allows the operator to select Position control, Draft control. Combined Position and Draft control and Float. CAUTION Hydraulic filter is to be changed at regular intervals as recommended. Hydraulic and Transmission parts may get damaged if filter is choked. Always use Genuine New Holland Filters. Figure 30 & 31 The system is operated by Draft control lever (1), Position control lever (2), Lift--O--Matic buttons (3), Response control (4), Sensitivity control (5) & External services valve (Tap--off) (6) Pre--operation checks DANGER Before starting the engine, always ensure that the Lift--O--Matic fast raise button is pushed in, to prevent inadvertent raising of three point linkage. IMPORTANT: Some mounted or semi--mounted equipment may interfere with and cause damage to tractor sheetmetal. To avoid damage check for clearance between tractor and implements. 1 2 3 30 4 6 5 31 SECTION 3 -- FIELD OPERATION 3--22 Position Control Operation Figure 32 Position control provides accurate control of implements such as sprayers, rakes, rotary tillers etc. that operate above the ground. Once set, Position control will maintain the selected implement height. IMPORTANT: Always set the system to Position control at any time when not actually operating in Draft control, such as when attaching or transporting equipment or when no equipment is attached. Move draft control lever (1), fully forward. Set implement position below or above ground by moving lever (2) forward to lower and rearward to lift. Implement movement will be proportional to lever travel. An adjustable stop (3) is provided to enable the lever to be returned to the required working position. 1 2 3 32 Draft Control Operation Figure 33 Draft control is most suitable for mounted or semi--mounted implements operating in the ground. Changes in the working depth or changes in soil resistance will cause draft loading on the implement to increase or decrease. When starting work, fully open the Response control valve and move the Position control lever (2) fully forward. Lower the implement in to the work using Draft control lever (1). Push the lever forward to increase the draft loading. Pull rearwards to reduce the draft loading. Forward movement of the Draft control lever will increase the implement depth and rearward movement will reduce the depth. Once set, tractor hydraulic system will automatically adjust the implement depth to maintain an even pull on the tractor and minimise wheel slip 1 2 33 SECTION 3 -- FIELD OPERATION 3--25 Sensitivity Control Figure 38 To adjust the sensitivity of hydraulic system when working in Draft control, levers (1) needs to be adjusted. UP -- Reduces sensitivity DOWN -- Increases sensitivity 1 38 Response Control Figure 39 The response control knob (1) varies the speed of drop of the lower links. CLOCKWISE rotation -- Increases speed of drop ANTICLOCKWISE rotation -- Decreases speed of drop IMPORTANT: To lock implements in transport position when driving on road, fully raise Position control lever (2) Figure 31 and screw in (rotate clockwise) knob (1) Figure 39. 1 39 Locking wedge Figure 40 During transportation locking wedge (1) must be positioned correctly in the slot (should be in disengaged position by means of locking lever) otherwise draft sensing system will be affected. However, during draft control operations, it should be removed from the slot. • To discharge the oil from external cylinder move the draft lever down the quadrant. 1 40 SECTION 3 -- FIELD OPERATION 3--26 Diverter Valve and External Supply Port Figure 41 The Diverter valve (1) is used to divert oil,normally flowing to the lift cylinder of the 3 point linkage, to the external supply port. A single cylinder can be connected to this external port and be operated by the draft control lever. -- Connect the port (2) to the single acting cylinder. -- For safety , fully lower the lift arms by putting down both draft and position control levers, to relieve any pressure in the system. -- Screw in completely the Diverter valve (1) in order to block the passage to hydraulic lift cylinder. -- To activate the external cylinder slowly move the draft lever up the quadrant. Lifting will start when draft lever reaches at approx. 186 mm of quadrant. -- To stop the movement of external cylinder move the draft lever a little forward to find the neutral position. -- To discharge the oil from external cylinder move the draft lever down the quadrant. NOTE: Keep Diverter valve (1) fully open during tractor hydraulic lift operations. 1 2 41 SECTION 3 -- FIELD OPERATION 3--27 TRACK ADJUSTMENTS Front Wheel Track Adjustment -- 2 Wheel Drive Figure 42 The front axle consists of a hollow centre beam(1) with a telescopic section (2) at each end. Seven holes at 50 mm intervals are provided in the telescopic sections for adjustment purposes. Adjustment of the front wheel track width is effected by extending both ends of the axle equally. To extend the axle, apply the hand brake and place blocks at the front and rear of the rear wheels. Jack up the front axle and place on axle stands. Remove the securing bolts (3) securing the left--hand telescopic section to the centre beam. Repeat the same for the right--hand side of the axle. 2 1 3 42 Track Rod -- Hydrostatic Steering (Right side -- illustrated) (if fitted) Figure 43 The tie rod located behind the axle must be disengaged to permit adjustment of the axle. The tie rod is telescopic and consists of a central hollow tube with a solid extendible section at each end. Remove the locating bolt (1) from both ends of the tie rod. The position for the setting of Hydrostatic steering cylinder will also change respectively. Reset the left and right axle telescopic sections, passing the securing bolts through the centre beam and telescopic sections, as indicated in Figure 42, see chart. 1 43 Figure 44 The track control rod is adjustable and consists of a central, hollow tube with a solid extendible section at each end. The left--hand end of the track control rod has a number of notches (1) at 50 mm intervals. A locating bolt (2) passes through a clamp and one of the notches in the solid section and locks the track rod assembly at the desired length. Additionally, the right--hand end of the track rod is threaded (3) to provide fine adjustment of toe--in. Remove the locating bolt (2) from the left--hand end of the track rod. This will permit the track rod to extend or retract freely. 2 1 44 SECTION 3 -- FIELD OPERATION 3--30 Front Wheel Toe--in Figure 48 After resetting the track width, the front wheel toe--in may require adjustment. For correct operation, the front wheels should be parallel or toe--in slightly. To measure the toe in proceed as follows: IMPORTANT: Incorrect toe--in setting may result in abnormal wear of front tyres. Measure the distance(1) between the wheel rims at hub height at the front of the wheels. Rotate both front wheels 180 and check the measurements again, this time at the rear of the wheels (2). This will eliminate wheel rim run--out errors. The correct toe--in setting is 0 -- 5 mm, i.e. the measurement taken at the front of the rims should be the same as the rear or be smaller by up to 5 mm. Should it be necessary to adjust the front wheel toe--in, proceed as follows: 48 Figure 49 Remove the nut (1) at the right end of the track control rod and withdraw track control rod from arm (2). Loosen the bolt (3) and rotate the threaded end to shorten or lengthen track rod assembly until the toe--in is correct. Tighten all bolts/nuts securely. WARNING Owners should ensure that all steering components are maintained in a satisfactory condition to ensure safe operation and in accordance with legal requirements. 3 1 2 49 3-- 31 A D F C B E 50 Rear Wheel Track Adjustment Figure 50 Tractor wheels are very heavy. Handle with care and ensure, when stored, they can not topple and cause injury. Rear wheel track adjustment is effected by changing the wheel rim relative to the centre disc, the rim and/or the disc relative to the axle hub or by interchanging the rear wheels. The sectioned drawings shown in the table illustrate the wheel rim and disc positions viewed from rear of the tractor relative to the hub at various track width settings. Track width (the distance between the centre of the tyres ) are nominal and may vary by as much as 13 mm. IMPORTANT: When interchanging left and right wheel assemblies, ensure the ‘V’ of the tyre tread remains pointing in the direction of forward travel of tractor for better grip. NOTE: With certain options and/or tyre sizes narrower track settings may not be possible due to minimal clearance between tyres and fenders or equipment. When refitting or adjusting a wheel, tighten the bolts to the following torques recheck after driving the tractor for 200m, after 1 hour and 8 hrs operation and thereafter at the 50 hour intervals: Rear disc to hub bolts 320 Nm Rear disc to rim nuts 235 Nm Never operate the tractor with loose wheel rim or disc. Always tighten nuts to the specified torque and at the recommended intervals.

This means that ballast may have to beadded or removed tomaintain the best tractor performance. Proper ballast will greatly improve tractor operation and ride. The amount of ballast required is effected by • Weight of tractor • Soil and Traction condition • Type of implement fully--mounted, semi--mounted or trailed. • Working speed. • Tractor horsepower load • Type and size of tyres • Tyre Pressure Do not usemore ballast than needed. Excess ballast should be removed when it is not required. Too little Ballast • Rough ride • Excessive wheel slip • Power loss • Tyre wear • Excessive fuel consumption • Lower productivity Too much Ballast • Higher maintenance costs • Increased driveline wear • Power loss • Increased soil compaction • Excessive fuel consumption • Lower productivity For maximum tractor performance in heavy draft conditions weight should be added to the tractor in the form of liquid ballast, cast iron weights or combination of both. Front end ballast may be required for stability and steering control when weight is transfered from the front to the rear wheels as the implement is raised by the tractor three--point linkage. When a rear mounted implement is raised to the transport position, the weight on the front wheels should be at least 20% of total tractor weight. Add front--end ballast as required, for stability during operation and transport. Ballasting of the front end may not always provide adequate stability if the tractor is operated at high speed on rough ground. Reduce tractor speed and be cautious under these conditions. When using front mounted equipment, it may be necessary to add weight to the rear wheels to maintain traction and stability. IMPORTANT: Only sufficient weight should be added to provide traction and stability. Adding more weight than necessary results in unnecessary loads being put on the tractor and higher fuel consumption. When adding weight adhere to the maximum tyre capacity loading stated in the tables at the end of this Section, Page 3--36. If further information or assistance is required on tractor weighing consult your Authorised Dealer. WARNING If proper stability cannot be achieved within the following weighting limitations, reduce the load on tractor until stability is restored SECTION 3 -- FIELD OPERATION 3--35 TYRE INFLATION Upon receiving your tractor, check the air pressure in the tyres and recheck every 50 hours or weekly. Refer below table for tyre pressure for normal operation. Operation Front Kg/cm2 Rear Kg/cm2 (psi) (psi) Field 2.2 (32) 0.8--1.1 (10--16) Haulage 2.2 (32) 1.1--1.8 (16--26) Refer to ‘TYRE PRESSURE AND LOAD’ tables on page 3--36 for more details. When checking tyre pressures, inspect the tyres for damaged tread and side walls. Incorrect pressure will lead to early tyre failure. Do not exceed the load for the pressures listed. Do not over or under inflate the tyre. DANGER Inflating or servicing tyres can be dangerous. Whenever possible, trained personnel should be called in to service or install tyres. In any event, to avoid the possiblity of serious or fatal injury, follow the safety precautions below • Do not inflate steering tyres above the manufaturer’s maximum pressure shown on the tyre or beyond the maximum shown in the Tyre Pressure and Load tables if the tyre is not marked with the maximum pressure. • Do not inflate a tyre that has been run flat or seriously under--inflated until it has been inspected for damage by a qualified person. • Torque wheel bolts to specification after re--installing thewheel. Check nut tightness daily until torque stabilises. • Refer to ‘TRACTOR BALLASTING’ section, page 3--32 before adding ballast to the tyres. • Ensure the jack is placed on a firm, level surface. • Ensure the jack has adequate capacity of lifting your tractor. • Use jack stands or other suitable blocking to support the tractor while repairing tyres. • Do not put any part of your body under the tractor or start the enginewhile the tractor is on the jack. • Never hit a tyre or rim with a hammer. • Ensure the rim is clean and free of rust or damage. Do not weld, braze, otherwise repair or use a damaged rim. • Do not inflate a tyre unless the rim is mounted on the tractor or is secured so that it will notmove if the tyre or rim should suddenly fail.

For haulage service, it is recommended that the tyre be inflated to the maximum pressure stipulated in the table. The above chart is for guidance only. For exact information regarding inflation pressures and loads for your particular tyres, consult your Authorised Dealer. SECTION 3 -- FIELD OPERATION 3--37 NOTES SECTION 4 -- LUBRICATION AND MAINTENANCE 4--3 FUEL REQUIREMENTS The quality of fuel used is an important factor for dependable performance and satisfactory engine life. Fuels must be clean, well--refined and non--corrosive to fuel system parts. Be sure to use fuel of a known quality from a reputable supplier. Use Number 2--D in temperatures above --7C (20F) Use Number 1--D in temperatures below --7C (20F) To obtain optimum combustion andminimum engine wear, the fuel selected for use should conform to the application and property requirements outlined in the following chart. DIESEL FUEL SELECTION CHART General fuel Classification Final Boiling Point (Max) Cetane Rating (Min) Sulphur Content (Max) No. 1--D 288C (550F) 45* 0.3% No. 2--D 357C (675F) 45 0.5% *When continually operating at low temperatures or high altitude, a minimum cetane rating of 45 is required. NOTE:When long periods of idiling or cold weather conditions below 0C(32F) are encountered or when continuously operating at an altitude above 5,000 ft. (1500 m) use Number 1--D fuel. Using diesel fuel with sulphur content above 0.5% requires more frequent oil and filter changes as noted in the maintenance schedule. The use of diesel fuel with a sulphur content above 1.3% is not recommended. For the best fuel economy, use Number 2--D fuel whenever temperatures allow. Do not use Number 2--D fuel at temperatures below --7C (20F). The cold temperatures will cause the fuel to thicken, which may prevent the engine from running (If this happens, contact your authorised New Holland dealer.) To be sure that a fuel meets the required properties, enlist the aid of a reputable fuel oil supplier. The responsibility for clean fuel lies with the fuel supplier as well as the fuel user. SECTION 4 -- LUBRICATION AND MAINTENANCE 4--4 FUEL STORAGE Take the following precautions to ensure that the stored fuel is kept free of dirt, water and other contaminants. 1. Store the fuel in black iron tanks, not galvanised tanks, as the zinc coating will react with the fuel and form compounds that will contaminate the injection pump and injectors. 2. Install bulk storage tanks away from direct sunlight Fig. 1. Keep the tank slightly tilted fig. 2 so that the sediments will settle away from the outlet pipe. 1 3. To facilitate moisture and sediment removal provide a drain plug at the lowest point at the end opposite the outlet pipe. 4. If fuel is not filtered from the storage tank, put a funnel with a fine mesh screen in the fuel tank filler neck when refuelling. 5. Arrange fuel purchase so summer grade fuels are not held over & used in winter. 2 FILLING THE FUEL TANK Clean the area around the fuel filler cap to prevent dirt from entering tank and contaminating the fuel. Remove the cap and place in a clean area during refuelling. After filling the tank, replace and tighten the fuel cap. Important:Always replace a lost or damaged cap with a genuine, original equipment replacement cap. Fuel Tank Capacity -- 62 Litres SECTION 4 -- LUBRICATION AND MAINTENANCE 4--5 GUARDS To gain access to perform inspection, lubrication and maintenance operations, the hood and certain access panelsmay need to beopened and removed. Access panels Figure 3 To gain access to air cleaner, battery & radiator slide the lock (1) to right and with the help of handle (2) raise the hood. 1 12 3 Figure 4 Tomaintain thehood in the raisedposition,a gas strut (1) is provided underside the hood ensuring access to the radiator cap(2) and air cleaner (3). 1 2 3 4 SECTION 4 -- LUBRICATION AND MAINTENANCE 4--8 OPERATION 3 Clean Air Pre--Cleaner ( If Fitted) Figure 8 The function of the pre--cleaner is to remove chaff, straw and the larger airborne material before the air passes to the air cleaner itself. Loosen the clamp (1) and remove the pre--cleaner (2). Clean and dry the complete pre--cleaner assembly and re--install. 2 1 8 OPERATION 4 Clean Air Cleaner Oil Bowl Figure 9 The oil bath air cleaner should be checked daily, or more often when working in extremely dusty conditions. The function of Air Cleaner is to remove impurities from the air but at the same time allow sufficient volume of air to enter the engine, to ensure complete burning of the fuel. The air cleaner will only fulfil this function if it is correctly and regularly maintained. A poorly maintained air cleaner means loss of power, excessive fuel consumption and a reduction in engine life. Release the four over centre catches to loosen the grip on the air cleaner bowl (1). Remove the bowl assembly and gauzefilter (2). Visually check the condition and level of oil in the inner cup of the bowl. If there is sediment collected, drain the oil and clean the inner cup and bowl with cloth and re--fill to the level mark. Do not fill above the level mark. 2 1 9 SECTION 4 -- LUBRICATION AND MAINTENANCE 4--9 OPERATION 5 Hydrostatic Steering Oil Level (If Power Steering fitted) Figure 10 Check the oil level through the transparent reservoir (1). Top up, as required. Ensure that the breather in the cap is completely clean. 1 10 OPERATION 6 Drain Water from Fuel Filter Figure 11 Important:Before loosening or disconnecting any part of the fuel injection system, thoroughly clean the area to be worked on to prevent contamination. Open the drain plugs on the primary and secondary filters by loosening the knobs (1). Allow the contaminated fuel to drain until clean fuel runs out. Catch the fuel in a suitable container and dispose off properly. Close both drain plugs. NOTE: Don’t close the fuel tank tap to avoid air lock in the system during this operation 1 11 Water Separator (If fitted) Figure 12 This is providedas anextra safety to the fuel supplied to engine.

The battery electrolyte level should be between min and max. lines provided on battery container. If necessary, top up with distiled or de--mineralised water until the level is correct. Do not overfill. Never use tap water or water from rain barrel or other source. To prevent the formation of corrosion, the terminals should be cleaned and smeared with petroleum jelly (Vaseline) only, no grease should be applied. Important:In the event that battery is severely discharged, such that the terminal voltage is below 7 volts, recovery will require a special charging procedure, Contact your Authorised New Holland Dealer. 25 OPERATION 15 Front Axle Housing Oil Level (for 4WD models only) Figure 26 Check the oil level as follows: -- Park the tractor on a level surface; -- Remove the plug (1). Some oil should flow out of the plug hole. If necessary, top up via plug hole (1) until the oil overflows. NOTE: For oil grades, see the lubrication chart. 26 SECTION 4 -- LUBRICATION AND MAINTENANCE 4--18 Important:Inspection of Outer Element Examine the element for damage by placing a light inside the element. see Figure 33 Discard the element if pin pricks of light can be seen or if there are areas where the paper appears thin. Check the element material for bunching; the metal casing for distortion and the rubber gasket for damage. Discard the filter element if it is damaged. Clean the inside of the air cleaner housing using a damp, lint--free cloth on a probe. Do not damage the inner filter element. Ensure that the inner end of the housing is clean and smooth, to ensure a good seating for the rubber seal on the element. 33 Install the cleaned outer element or new outer element by gently pushing it inside the housing in clockwise direction. While fitting back the cover make sure that the dust cup/ejector (2) facing downward Fig. 27 Check all the air intake hoses,for damages and replaceas necessary.Checkclamps for tightness. Replacement of inner element The inner element to be removed only at the time of replacement.It should never be cleaned.The inner element should be replaced after 3 outer element replacements,or,every, 2700hrs.whichever, is earlier Follow the similar instruction of removing & fitting outer element from casing to replace inner element. NOTE: Do not wash tractor when engine is running as water entry will damage the filters. Operation no 17 Change Fuel Filter (Primary) Figure 34 & 35 To replace the fuel filter elements proceed as follows: 1. Clean the filter assembly externally. 2. Loosen the bleed screw (1). 3. Unscrew the primary fuel filter (2) and discard 4. Clean the filter mounting surface. Apply a thin film of clean oil on the new oil filter sealing ring and install the filter. Turn until the sealing ring contacts the mounting surface, then tighten an additional 3/4 to 1 full turn. Do not over tighten. 5. With the bleed screw loose, prime the fuel system with the help of hand prime, Figure 35 6. Start the engine and ensure no fuel is leaking. 1 2 34 2 35 SECTION 4 -- LUBRICATION AND MAINTENANCE 4--19 Operation 18 Fuel Feed pump Filter Figure 36 Themain purpose of this strainer (1) is to protect the fuel feed pump. It has a comparatively course element. This element is contained in an easily removable bowl and should be cleaned. When reassembled, make sure that a good joint is made between the top of the bowl and filter body as any leakage of air here may cause air locks in the fuel system. 1 36 SECTION 4 -- LUBRICATION AND MAINTENANCE 4--20 OPERATION 19 Hydrostatic Steering Oil Filter (If Power Steering fitted) Figure 37 Clean hydrostatic steering filter with diesel fuel or petrol and dry before installing. Refill the reservoir with oil up to the top of the filler neck. Replace the cap. With the engine running, bleed the system by turning the steering wheel from lock to lock several times. Top up the reservoir, as required. Use only Genuine New Holland Transmission Oil 37 OPERATION 20 Change Engine Oil Figure 38 & 39 Warm the engine to operating temperature. Stop the engine, remove the drain plug (1), Figure 38 and collect the oil in a suitable container. Replace thedrain plugand refill the enginewith clean oil through the filler cap (1), Figure 39 & 40 (according to models). Ensure that the tractor is parked on level ground. Run the engine for a minute or so, to circulate the oil, then stop the engine. Wait for a short period to allow the oil to drain back, to sump, then check the oil level by means of the dipstick. Add clean oil, as necessary, until the oil level is between max. and min marks on the dipstick. NOTE: Do not fill above the UPPER MARK OF dipstick. Excessive oil will burn off creating smoke within a short time and give a false impression of oil consumption. Do not operate the enginewith oil level below the the lower mark. Important:Use only Genuine Engine Oil. NOTE: Always change engine oil filter, when changing engine oil. WARNING Be careful to avoid contact with hot engine oil. If the engine oil is extremely hot, allow it to cool to a moderately warm temperature before proceeding. 1 38 1 39 1 40
