Checking the Engine Oil Level

the neutral locked position and set the parking brake.

(Fig. 36).

Do not overfill the crankcase with oil
because the engine may be damaged. Do not run engine
with oil below the low mark because the engine may be
damaged.
Changing the Engine Oil
Note: A hose was included in loose parts. Use this hose to
direct the engine oil into the drain pan. The hose may be
cut to a desired length.
1. Start the engine and let it run five minutes. This warms
the oil so it drains better.
2. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Clean around the oil dipstick (Fig. 36) so dirt cannot
fall into engine.
5. Place the hose onto oil drain valve to direct oil into
drain pan (Fig. 37).
