Checking Oil Level
1. Park the machine on a level surface, disengage the
power take off (PTO) and turn the ignition key to
"OFF" to stop the engine. Remove the key.
2. Clean around the oil dipstick (Fig. 36) so dirt cannot
fall into the filler hole and damage the engine.
3. Unscrew the oil dipstick and wipe the metal end clean
(Fig. 36).
4. Slide the oil dipstick fully into the filler tube, do not
thread onto tube (Fig. 36). Pull the dipstick out and
look at the metal end. 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.

Changing/Draining 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. Then disengage the power take off (PTO),
set the parking brake, and turn the ignition key to
"OFF" to stop the engine. Remove the key.
3. Place a pan below the oil drain. Remove the oil drain
cap (Fig. 37).
4. When oil has drained completely, install the drain cap.
Note: Dispose of the used oil at a certified recycling
center.

Oil Level, page 29. Slowly add additional oil to bring
to "FULL" mark on dipstick.
