Inspect clutch and ensure that the scribed markings
made on the clutch plates have changed position.
Slippage has not occurred if any two marks on the
friction disk and plate are still aligned. A clutch that
has not slipped must be disassembled to separate
the friction disk plates. See “Clutch Disassembly,
Inspection & Assembly” on page 45 below.

Drivelines With Slip Clutches
!
WARNING
!
CAUTION
Friction clutches must be capable of slippage during
operation to protect gearboxes, drivelines, and other
drive train parts. Friction clutches should be “run-in” prior
to initial operation and after periods of inactivity to
remove any oxidation from the friction surfaces. Repeat
“run-in” at the beginning of each season and when
moisture seizes the inner friction plates.

Clutch Types

Refer to Figure 5-9:
Determine which friction clutch your cutter has. Follow
“run-in” instructions for your specific clutch type. Refer to
this page for “Type A Clutches” and page 46 for
“Type B Clutches”.

IMPORTANT: Prior to initial operation and after long
periods of inactivity, slip friction disks to remove
oxidation and moisture. Moisture allows disks to slip
easily. Oxidation can prevent disk from slipping
causing driveline damage. This damage is NOT
covered under the warranty!
