Checking The Rotor; Checking The Rear-Roller Bearing Adjustment; Checking The Rear-Roller Scraper Wire Tension - Toro LT-F3000 Operator's Manual

Checking the Rotor

Service Interval: Before each use or daily—Check for
any unusual vibration of the rotor.
Every 50 hours—Check for excessive play in
the rotor bearings.
To check for any unusual vibration of the rotor, run
each cutting unit in turn at full engine speed.
Note:
If there is any unusual vibration, check for
damage or excessive wear of the rotor or blades. All
blades need to have a similar level of wear as their
weight affects the balance of the rotor.
Note:
If you cannot resolve the vibration issue,
contact your authorized Toro distributor.
1. Raise and support the cutting unit.
2. Grip the rotor at each end and check for
excessive end play.
Note:
If you detect the rotor has excessive end
play, contact your authorized Toro distributor.
Note:
If the rotor needs to be replaced
or balanced, contact your authorized Toro
distributor.
Checking the Rear-Roller
Bearing Adjustment
Service Interval: Every 50 hours
Important:
Keep the roller bearings on the cutting
units in good adjustment to ensure maximum
working life. Excessive roller-end play causes
premature bearing damage.
1. Grip the roller and move from side to side and
up and down.
2. If there is excessive movement, carefully tighten
the nuts at each end of the roller with the wrench
just enough to remove any end play
Note:
The roller should still rotate freely after
adjustment. Overtightening the nuts could lead
to premature bearing damage.
Note:
Adjust the nuts by an equal amount at
both ends of the roller.
