Driveline Protection

!CAUTION!

Engage parking brake, disengage PTO, shut off tractor, and remove key before working on or around the driveline and/or slip clutch.

!CAUTION!

Slip clutches that have been in use or have been slipped for only two or three seconds during run-in may be too hot to touch. Allow a hot clutch to cool before working on it.

Drive components are protected from shock loads with a friction slip clutch. The clutch must be capable of slippage during operation to protect the gearbox, driveline and other drive train parts.

Friction clutches should be “run-in” prior to initial operation and after long periods of inactivity to remove any oxidation that may have accumulated on the friction surfaces. Repeat “run-in” instructions at the beginning of each season and when moisture and/or condensation seizes the inner friction plates.

Refer to Figure 5-8 to determine which friction clutch your mower has. Follow “run-in” instructions on the following pages for your specific clutch type.

Type A Clutches

Clutch Run-In

Refer to Figure 5-9 (View - A):

1.Using a pencil or other marker, scribe a line across the exposed edges of the clutch plates and friction disks.

2.Tighten all 4 nuts uniformly until spring load is low enough that the clutch slips freely with PTO engaged.

3.Make sure the area is clear of all bystanders and machine is safe to operate.

4.Start tractor and engage PTO for 2-3 seconds to permit slippage of clutch surfaces. Disengage PTO, then re-engage a second time for 2-3 seconds. Disengage PTO, shut off tractor and remove key. Wait for all components to stop before dismounting from tractor.

5.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” below.

Refer to Figure 5-9 (View - B):

6.If no two marks on the friction disk and plate are still aligned, Turn all 4 nuts fully back.

7.Allow clutch to cool to ambient temperature before operating again. Clutch is now ready for use.

8.The clutch should be checked during the first hour of cutting and periodically each week. An additional set of scribe marks can be added to check for slippage.

Clutch Disassembly, Inspection & Assembly

If clutch run-in procedure above indicates that one or more of the friction disks did not slip, then the clutch must be disassembled into separate friction disks.

IMPORTANT: Before proceeding, secure clutch firmly in a vise or other clamping device to prevent injury.
