Changing 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 ensure that the oil
drains completely.
3. Disengage the PTO, set the parking brake, lower the
attachment lift, stop the engine, and remove the
ignition key.
4. Open the hood.
Caution
Components under the hood will be hot if the
tractor has been running. If you touch hot
components you may be burned.
Allow the tractor to cool before performing
maintenance or touching components under the
hood.
5. Place a pan below the oil drain.
6. Open the drain by turning it counterclockwise 1/8 turn
and pulling out on it (Fig. 27).
