Checking the Oil Level
1. Park the tractor on a level surface.
2. Disengage the blades (PTO).
3. Set the parking brake.
4. Stop the engine and wait for all moving parts to stop.
5. Remove the ignition key.
6. Open the hood.
7. Clean around the oil dipstick (Fig. 18) so that dirt
cannot fall into the filler hole and damage the engine.

8. Unscrew the oil dipstick and wipe the metal end clean
(Fig. 18).
9. Screw the oil dipstick fully onto the filler tube (Fig. 18).
10. Unscrew the dipstick again and look at the metal end. If
the oil level is low, slowly pour only enough oil into the
filler tube to raise the level to the Full mark on the
dipstick.
11. Start the engine and let it idle for 30 seconds.
12. Stop the engine and wait for 30 seconds.
13. Check the oil level again and add oil if necessary.
Important Do not overfill the crankcase with oil and
run the engine; engine damage may result.
Changing the Oil
1. Start the engine and let it run for 5 minutes.
Note: This warms the oil so that it drains better.
2. Park the tractor so that the drain side is slightly lower
than the other side to ensure that the oil drains
completely.
3. Disengage the blades (PTO).
4. Set the parking brake.
5. Stop the engine and wait for all moving parts to stop.
6. Remove the ignition key.
7. Open the hood.
