7. Loosen filter 1/2 turn and allow a small amount
of oil to leak from the oil filter (this allows air to
be purged from the oil filter and supply hose from
the hydraulic reservoir). Turn filter clockwise
until rubber seal contacts the filter adapter. Then
tighten the filter an additional 2/3 to 3/4 turn.
8. Raise the rear of machine up and support with
jack stands (or equivalent support) just high
enough to allow drive wheels to turn freely.
CAUTION
Raising the mower for service or maintenance
relying solely on mechanical or hydraulic
jacks could be dangerous. The mechanical or
hydraulic jacks may not be enough support
or may malfunction allowing the unit to fall,
which could cause injury.

Do Not rely solely on mechanical or hydraulic
jacks for support. Use adequate jack stands
or equivalent support.
9. Start engine and move throttle control ahead to
full throttle position. Move motion control levers
inward (together) and move both levers forward
with equal pressure, and run for one minute. Shut
down the machine, allow the hydros to cool and
recheck oil level.
If either drive wheel does not rotate, one or both
of the charge pumps (located on the top of the
main pump as shown in Figure 25) may have lost
their "prime". Refer to Hydraulic System Air
Purge section.
