Pre-Maintenance
Procedures
Important:
The fasteners on the covers of this
machine are designed to remain on the cover
after removal. Loosen all the fasteners on each
cover a few turns so that the cover is loose but
still attached, then go back and loosen them
until the cover comes free. This prevents you
from accidentally stripping the bolts free of the
retainers.

Maintenance Safety

•
Before adjusting, cleaning, repairing, or leaving
the machine, do the following:
– Park the machine on a level surface.
– Move the throttle switch to the low-idle position.
– Disengage the cutting units.
– Lower the cutting units.
– Ensure that the traction is in neutral.
– Engage the parking brake.
– Shut off the engine and remove the key.
– Wait for all moving parts to stop.
– Allow machine components to cool before
performing maintenance.
•
If the cutting units are in the transport position, use
the positive mechanical lock (if available) before
you leave the machine unattended.
•
If possible, do not perform maintenance while the
engine is running. Keep away from moving parts.
•
Use jack stands to support the machine or
components when required.
•
Carefully release pressure from components with
stored energy.

Lubrication

Greasing the Bearings and
Bushings
Service Interval: Every 50 hours (more often in dirty
or dusty conditions and after every
washing).
The machine has grease fittings that you must
lubricate regularly with No. 2 lithium grease. Lubricate
more often in dirty or dusty conditions because dirt
can get into the bearings and bushings and cause
accelerated wear.
1. Wipe the grease fittings clean so that foreign
matter cannot be forced into the bearing or
bushing.
2. Pump grease into the fittings.
3. Wipe off excess grease.
Note:
Improper wash-down procedures can
negatively affect bearing life. Do not wash down
the machine when it is still hot and avoid directing
high-pressure or high-volume spray at the bearings
or seals.
Servicing the Mower-Deck
Gearbox Lubricant
The gear box is designed to operate with SAE
EP90W gear lube. Although the gearbox comes
from the factory with lubricant, check the level of the
lubricant in the cutting unit before operating it and as
recommended in the
(page 32).
Checking the Mower-Deck
Gearbox Lubricant
Service Interval: Every 150 hours
1. Position the machine and mower deck on a level
surface.
2. Lower the mower deck to the 2.5 cm (1 inch)
height of cut.
3. Disengage the PTO, move the motion-control
levers to the N
engage the parking brake.
