conditions are extremely dusty or sandy.
Oil Type: Detergent oil (API service SF, SG, SH, or SJ)
Crankcase Capacity: 58 ounces (1.7 liter) with the filter

Checking the Engine Oil Level
1. Park the machine on a level surface.
2. Disengage the PTO and set the parking brake.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Clean around the oil dipstick (Fig. 31) so that dirt
cannot fall into the filler hole and damage the engine.

5. Unscrew the oil dipstick and wipe the end clean
(Fig. 31).
6. Slide the oil dipstick fully into the filler tube, but do
not thread it onto the tube (Fig. 31).
7. Pull the dipstick out and look at the end. If the 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 and
run the engine; engine damage can result.
Changing the Oil
1. Start the engine and let it run 5 minutes. This warms the
oil so that 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 and set the parking brake.
4. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
5. Slide the drain hose over the oil drain valve.
6. Place a pan below the drain hose.
7. Rotate oil drain valve to allow oil to drain (Fig. 32).

8. When oil has drained completely, close the drain valve.
9. Remove the drain hose (Fig. 32).
Note: Dispose of the used oil at a recycling center.
10. Slowly pour approximately 80% of the specified oil
(refer to Service Interval/Specification on page 30) into
the filler cap (Fig. 31).
11. Check the oil level; refer to Checking the Engine Oil
Level on page 30.
12. Slowly add the additional oil to bring it to the Full
mark.
