Changing the Oil
Service Interval:
After the first 5 hours
Every 50 hours Change it more
often under a heavy load or in high
temperatures.
1. Start the engine and let it run for 5 minutes.
Note:
This warms the oil so that it will drain more
easily.
2. Park the tractor so that the left side is slightly lower
than the right side to ensure that the oil drains
completely.
3. Disengage the blade control (PTO).
4. Set the parking brake.
5. Stop the engine, wait for all moving parts to stop, and
remove the key before leaving the operating position.
6. Open the hood.
7. Place a drain pan below the oil drain plug and
remove it (Figure 27).
8. When the oil has drained completely, install the oil
drain plug.
Note:
Dispose of the used oil at a certified recycling
center.
9. Change the oil filter, if necessary. Refer to Changing
the Oil Filter.
10. Slowly pour approximately 80% of the specified
amount of oil into the fill hole (Figure 27). Check the
oil level; refer to 4 and 5 of Checking the Oil Level.
Changing the Oil Filter
Service Interval:
Every 100 hours
Note:
Change the oil filter more frequently when the
operating conditions are extremely dusty or sandy.
1. Drain the oil from the engine; refer to Changing and
Draining the Oil.
