2. Open the transaxle’s bypass valves (see
Pushing the
Rider by Hand
for the location and function of the bypass
valves), start the engine, release the parking brake, and
slowly move the zero-turn rider’s ground speed control
levers in both forward and reverse directions (5 to 6
times), as air is purged from the unit, the oil level will
drop.
3. Stop the engine and engage the parking brake.
4. Close the transaxle’s bypass valves, start the engine,
release the parking brake, and slowly move the zero-turn
rider’s ground speed control levers in both forward and
reverse directions (5 to 6 times), as air is purged from the
unit, the oil level will drop.
5. Stop the engine. Remove the jack stands from
underneath the machine.
6. Repeat the process detailed above but with the unit's
drive wheels on the ground. The procedure should be
performed in an area free of any objects or bystanders.
It may be necessary to repeat the process detailed above
until all the air is completely purged from the system. When
the transaxles/transmissions operate at normal noise levels
and move smoothly forward and reverse at normal speeds,
then the transaxles/transmissions are considered purged.
Checking Tire Pressures
Tire pressure should be checked periodically, and maintained
at the levels shown in the Specifications chart. Note that
these pressures may differ slightly from the "Max Inflation"
stamped on the side-wall of the tires. The pressures shown
provide proper traction and extend tire life.
Lubrication
Lubricate the unit at the locations shown in Figures 32, 33,
and 34 as well as the following lubrication points:
Grease:
• front caster wheel axles & yokes
• deck lift pivot blocks
• mower deck spindles
• transmission cradle pivot points
Use grease fittings when present. Disassemble parts to apply
grease to moving parts when grease fittings are not installed.
Not all greases are compatible. Red grease (p/n 5022285)
is recommended, automotive-type, high-temperature, lithium
grease may be used when this is not available.
Oil:
• control handle pivots
• seat plate pivots
• deck lift pivots
• discharge chute hinge
Generally, all moving metal parts should be oiled where
contact is made with other parts. Keep oil and grease off belts
and pulleys. Remember to wipe fitting and surfaces clean
both before and after lubrication.
