Drive System
Maintenance
Checking the Torque of the
Wheel Nuts
Service Interval: After the first 8 hours
Every 200 hours
Park the machine on a level surface, lower the cutting units,
engage the parking brake, shut off the engine, and remove
the key.
WARNING
Failure to maintain proper torque of the wheel nuts
could result in failure or loss of a wheel and may
result in personal injury.
Torque the front and rear wheel nuts to 115 to
136 N∙m (85 to 100 ft-lb) after 1 to 4 hours of
operation and again after 8 hours of operation.
Torque the wheel nuts every 200 hours thereafter.
Note: The front wheel nuts are 1/2–20 UNF. The rear wheel
nuts are M12 x 1.6-6H (metric).
Checking the Planetary Gear
Drive Oil
Service Interval: Every 400 hours
Check the oil level after every 400 hours of operation. Use
high-quality SAE 85W-140 gear lube as a replacement.
1. Park the machine on a level surface, lower the cutting
units, engage the parking brake, shut off the engine,
and remove the key.
2. Position the wheel so that 1 check plug
the 12 o'clock position and the other is at the 3 o'clock
position.

3. Remove the plug at the 3 o'clock position
Note: The oil level should be at the bottom of the
hole.
4. If the oil level is low, remove the plug at the 12 o'clock
position and add oil until it begins to flow out of the
hole at the 3 o'clock position.
5. Install both plugs.
6. Repeat steps 2 through
gear assembly.
Changing the Planetary Gear
Drive Oil
Service Interval: After the first 200 hours
Every 800 hours (or yearly, whichever comes first).
Change the oil initially after first 200 hours of operation.
Thereafter, change the oil every 800 hours, or yearly,
whichever occurs first. Use a high-quality SAE 85W-140 gear
lube as a replacement.
1. Park the machine on a level surface, lower the cutting
units, engage the parking brake, shut off the engine,
and remove the key.
2. Position a wheel so that 1 of the check plugs is at the
lowest (6 o'clock) position

3. Place a drain pan under the planetary hub, remove the
plug, and allow the oil to drain.
4. Place a drain pan under the brake housing, remove the
drain plug, and allow the oil to drain
