WARNING: Before performing any maintenance or repairs, disengage PTO, move shift lever into neutral position, set parking brake, stop engine and remove key to prevent unintended starting.

Engine

Refer to the engine manufacturer’s Operator/Owner Manual for engine maintenance instructions.

Check engine oil level before each use as instructed in the engine manufacturer’s Operator/Owner Manual packed with your unit. Follow the instructions carefully.

Changing Engine Oil

NOTE: Depending on the engine model found on your tractor, it may be necessary to remove the tractor’s side panel in order to replace the oil filter (if so equipped).

Changing Engine Oil

For draining oil from the engine’s crankcase of select model tractors, a plastic oil drain sleeve is packed with this Operator’s Manual. To drain the oil, proceed as follows:

Unscrew the oil fill cap and remove the dipstick from the oil fill tube.

Snap the small end of oil drain sleeve onto the oil sump. See Figure 20.
