Hoses. Make any necessary repairs before using the tractor. Use the lower gears when pulling heavy loads and avoid continuous operation at constant engine speeds. You will save fuel and minimise engine wear by selecting the correct gears for particular operation. Before operating the tractor. ensure that you are thoroughly familiar with the location and operation of the controls. Operating in a high gear under heavy load may cause engine overloading. vi. Perform daily lubrication and maintenance operation in accordance with Section 4. Tyres for damage. Avoid overloading the engine. 3--2 ii. ii. Operating the tractor in a low gear with light load and high engine speed will waste fuel. Pay particular attention and check the following items: i. front wheel drive axle or other components that could be damaged by contacting the chain or by heavy loading. When using a chain. rear tow hitch or the three--point hitch.FIELD OPERATION TOWING THE TRACTOR IMPORTANT: The tractor should only be towed a short distance. IMPORTANT: Do not chain around the four wheel drive shaft. Tow the tractor from the rear using only the drawbar. then the selector control must be in the off position. IMPORTANT: If it is necessary to tow the tractor.SECTION 3 -. observe the following • Only tow a short distance • Keep speed below 5 MPH (8km/h) • If possible. such as out of a building. regardless of the position of the 4WD activation lever. run the engine to provide lubrication to the transmission and power steering. Securely chain the tractor to the transporter. WARNING Do not use cables or rope to tow the tractor. If the cable or rope breaks or slips. Have an operator steer and brake the tractor. Do not tow on roadways or as a method of transport. To avoid damaging the transmission or other components that turn but are not lubricated during towing. it may whip with sufficient force to cause serious injury. 3--3 . all gear levers must be moved to the neutral position before stopping the engine otherwise damage to transmission components may occur during towing. it will drop down instead of flying up. Tow the tractor from the front using the tow pin in the front weights or front support. steering cylinders. The steering is much slower and steering wheel effort is much greater without the engine running. Use the drawbar hanger for a rear tie down point. Use a strong chain when towing the tractor. CARRYING THE TRACTOR ON A TRANSPORTER Transport the tractor with all four wheels on a flat bed trailer or truck. CAUTION Do not tow the tractor faster than 8 Km/h (5MPH). attach the chain with the hook open side facing up. If creeper gears (reduction gear set) are fitted. If the hook slips. NOTE: Four wheel drive will be engaged if the engine is not running. SECTION 3 -- FIELD OPERATION STARTING THE TRACTOR USING JUMP LEADS (BOOSTER CABLES) Figure 1 + -- WARNING Always sit in the driver’s seat to operate the starter. If the key--start switch is by--passed and the tractor has been left in gear, sudden and unexpected movement of the tractor or a tractor runaway may result which could cause serious injury. Wear eye protection when starting the tractor with jump leads or when charging the battery. + -- 1 If it is necessary to use jump leads (booster cables) to start the tractor, use only heavy duty leads (Refer to Figure 1) and proceed as follows: • Connect one end of the red jump lead to the tractor battery positive (+) terminal and the other end to the auxilary battery positive (+) terminal. • Connect one end of the black jump lead to the tractor battery negative (--) terminal and the other end to the auxilliary battery negative (--) terminal. Follow the starting procedure previously described. • When the engine starts allow it to run at idle rpm. Turn on all electrical equipment (lights, etc.) then disconnect the jump leads, negative (black) first then positive (red). This will help protect the alternator from possible damage due to changes in load. IMPORTANT: When using an auxillary battery to start the engine, ensure that the polarity of the jump leads is correct -- positive to positive, negative to negative, otherwise the alternator may be damaged. Only use an auxiiary battery if the tractor batteries are discharged. Excessive amperage (above 1600 cca) may damage the starting motor. In the event of the batteries being severly discharged, such that terminal voltage is below 7 volts, recovery will require a special charging procedure. See your authorised New Holland Dealer. 3--4 SECTION 3 -- FIELD OPERATION 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 1 2 3 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.

When using front mounted equipment. Proper ballast will greatly improve tractor operation and ride.SECTION 3 -. If further information or assistance is required on tractor weighing consult your Authorised Dealer. The amount of ballast required is effected by When a rear mounted implement is raised to the transport position. WARNING If proper stability cannot be achieved within the following weighting limitations. the weight on the front wheels should be at least 20% of total tractor weight. 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 3--32 Add front--end ballast as required. 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. Ballasting of the front end may not always provide adequate stability if the tractor is operated at high speed on rough ground. This means that ballast may have to be added or removed to maintain the best tractor performance. • Tractor horsepower load • Type and size of tyres • Tyre Pressure Do not use more ballast than needed. Reduce tractor speed and be cautious under these conditions. When adding weight adhere to the maximum tyre capacity loading stated in the tables at the end of this Section. reduce the load on tractor until stability is restored . cast iron weights or combination of both.FIELD OPERATION BALLASTING AND TYRES Selecting ballast For maximum tractor performance in heavy draft conditions weight should be added to the tractor in the form of liquid ballast. Adding more weight than necessary results in unnecessary loads being put on the tractor and higher fuel consumption. When tractor horsepower loads vary the optimum weight of the tractor will change. Excess ballast should be removed when it is not required. IMPORTANT: Only sufficient weight should be added to provide traction and stability.
