Changing Engine Oil
NOTE : Depending on the engine model found on your
tractor, it may be necessary to remove the tractor’s side
panel in order to replace the oil filter (if so equipped).
1. Pop open the protective cap on the end of the oil
drain valve to expose the drain port. See Figure 20.
2. Remove the oil fill cap/ dipstick from the oil fill tube.
3. Push the oil drain hose (packed with this manual)
onto the oil drain port. Route the opposite end of the
hose into an appropriate oil collection container with
a capacity great enough to collect the used oil.
4. After the oil has finished draining, push the oil drain
valve back in, rotate it clockwise to lock the valve
closed and re-cap the end of the oil drain valve to
keep debris from entering the drain port.
5. Service the oil filter (if so equipped) as instructed in
the separate Engine Operator/Owner Manual packed
with your unit.
Perform the above steps in the opposite order after oil
has finished draining.
6. Refill the engine with new motor oil as instructed in
the Engine Operator/Owner Manual packed with your
unit.
