Checking the Oil Level
Note: Check the oil when the engine is cold.
1. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Clean around the oil dipstick (Fig. 37) so dirt cannot
fall into the filler hole and damage the engine.
4. Pull the oil dipstick and wipe the metal end clean
(Fig. 37).
5. Slide the oil dipstick fully into the filler tube. Pull the
dipstick out and look at the metal end (Fig. 37). If oil
level is low, slowly pour only enough oil into the filler
tube to raise the level to the full mark.
Important 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 Oil
1. Start the engine and let it run five minutes. This warms
the oil so it drains better.
2. Park the machine so that the drain side is slightly
lower than the opposite side to assure the oil drains
completely. Disengage the power take off (PTO), set
the parking brake, and turn the ignition key to off.
Remove the key.
3. Place a pan below the oil drain. Rotate the oil drain
valve to allow the oil to drain (Fig. 38).

4. When the oil has drained completely, close the drain
valve.
Note: Dispose of the used oil at a certified recycling
center.
5. Slowly pour approximately 80% of the specified oil
into the filler cap (Fig. 37). Refer to Servicing the
Engine Oil, page 32.
6. Check the oil level; refer to Checking the Oil Level,
page 32.
7. Slowly add additional oil to bring it to the full mark.
