1. Wipe each nipple clean first.
2. Pump grease into the steering linkage, front axle pivot, front wheel spindles (2WD only), power steering cylinder, the clutch and brake pedal shaft and the 3-point linkage until fresh grease just shows.
3. Wipe off the surplus.

Tools: Grease gun

1. Run the engine until it is just warm, stop it and take the key out. Chock the wheels.
2. Put the tray under the sump, take out the drain plug and let the oil run out, then refit the plug.
3. Unscrew the old oil filter. Take care, as oil will run out of it.
4. Smear a little clean engine oil on the rubber seal of the new filter. Screw it on until the seal just touches, then turn it a further three-quarters of a turn by hand.
5. Fill with oil to the dipstick mark. Start the engine, check the filter and plug for leaks, stop it and top up. The level drops a little once a new filter is fitted.

Tools: Drain tray (10 L), Socket for the drain plug, Oil filter strap wrench, Funnel

1. Make sure there is fuel in the tank. Turn the fuel shut-off valve to C (closed).
2. Take off the sediment bowl. Turn the shut-off valve to O and let fuel flow until only clean fuel, no water, comes from the filter base.
3. Close the valve, refit the bowl, open the valve again and bleed the fuel system.

Tools: Small container, Rags

1. Push down on the air cleaner cover and turn it anticlockwise to take it off. Pull out the outer element.
2. Blow compressed air, under 30 psi, from the inside of the element to the outside. Keep the nozzle away from the paper.
3. Hold a light inside the element. Replace it if you see any leaks in the paper or damage to the end seals.
4. Wipe dirt out of the canister, refit the element and fit the cover.

Tools: Compressed air line (under 30 psi), Torch

1. Turn the fuel shut-off valve to C (closed). Unscrew the retaining nut and take off the sediment bowl.
2. Open the valve briefly so fuel flows until it runs clear, then close it.
3. Fit the new element, check the two O-rings, fit the spring between the element and the bowl, and refit the bowl.
4. Open the shut-off valve to O. Bleed the fuel system: open the bleed screw on the fuel pump until air-free fuel flows, close it, set full throttle and turn the engine over for a few seconds.

Tools: Small container, Rags

1. Warm the oil by working the tractor, but let it cool so it is not scalding hot. Oil drains best warm.
2. Take out the filler plug and the drain plugs (transmission and rear axle) and let all the oil drain. Refit the plugs.
3. Unscrew the old hydraulic filter (and the HST filter on HST models). Smear a little oil on the new seal, screw on until it touches, then three-quarters of a turn more by hand.
4. Fill with the specified oil to the correct level on the dipstick, refit the dipstick and filler plug.
5. Run the engine, check the filter for leaks, stop it and recheck the level.

1. Take out the drain plug and drain the oil while it is still warm. Refit the plug.
2. Take out the dipstick or filler plug and fill with the specified oil.
3. Refit the dipstick or plug and check for leaks.

Tools: Drain tray, Socket for the drain plug, Funnel

1. Detach the clutch assembly as the handbook shows, then take out the check plug and drain the oil.
2. Fill through the check plug hole with the specified oil. It is full when the oil is level with the bottom of the check plug opening.
3. Refit the check plug and the clutch assembly.

Tools: Drain tray, Spanner for the check plug

1. Warm the oil a little, then take out the drain plug and drain the oil. Refit the plug.
2. Turn the filter and reservoir assembly anticlockwise to take it off. Smear a little oil on the new seal and tighten it until the seal touches, then three-quarters of a turn more.
3. Take out the filler plug or dipstick and fill the reservoir with the specified oil. Refit it.

1. Take off the cover and the outer element to reach the inner element.
2. Pull out the old inner element and wipe the canister clean. Check the seals of the new element.
3. Push the new inner element into the canister, refit the outer element over it and fit the cover.
