Exmark Premium Hydro Oil is recommended.
Refer to the chart for an acceptable alternative:
Hydro Oil
Exmark Premium Hydro
Oil (Preferred)
Mobil 1 15W50
Torque plugs to 180 in-lb (244 N-m). Continue to
add Exmark Premium Hydro Oil until it reaches
the FULL COLD line on the expansion reservoir.
6. 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 unit 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.
7. Start engine and move throttle control ahead to
1/2 throttle position. Disengage parking brake.
WARNING
Engine must be running and drive wheels
must be turning so motion control adjustment
can be performed. Contact with moving parts
or hot surfaces may cause personal injury.
Keep fingers, hands, and clothing clear of
rotating components and hot surfaces.
A. With the engine running, slowly move the
directional control in both forward and
reverse directions (5 to 6 times). Check the oil
level, and add oil as required after stopping
the engine.
B. It may be necessary to repeat step A. until all
the air is completely purged from the system.
When the transaxle operates at normal noise
levels and moves smoothly forward and
reverse at normal speeds, then the transaxle
is considered purged.

Note: Do Not change the hydraulic system oil
(except for what can be drained when changing filter),
unless it is felt the oil has been contaminated or been
extremely hot.
Changing oil unnecessarily could damage hydraulic
system by introducing contaminants into the system.
