Changing/Draining the Engine Oil
1. Start the engine and let it run for 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, lower the
attachment lift, and turn the ignition key to
"STOP" to stop the engine. Remove the ignition
key.
3. Open the hood.

POTENTIAL HAZARD
Components under the hood will be hot if
the tractor has been running.
WHAT CAN HAPPEN
Touching hot components can cause burns.
HOW TO AVOID THE HAZARD
Allow the tractor to cool before performing
maintenance or touching components
under the hood.
4. Place a pan below the oil drain. Open the drain
by turning it counterclockwise 1/8 turn and
pulling out on it (Fig. 31).
5. When the oil has drained completely, close the
drain by pushing it in and turning it clockwise,
1/8 turn.
Note: Dispose of the used oil at a certified
recycling center.
6. Remove the oil filler cap (Fig. 30) and refill the
engine with a high–quality, API Service SG or
SH engine oil (see viscosity chart).
7. Slowly pour approximately 80% of the specified
amount of oil into the filler tube (Fig. 30). Now
check the oil level; refer to Checking the Engine
Oil Level, page 14. Slowly add additional oil to
bring the oil level to the FULL mark on the
dipstick.
