Protected Drivelines

WARNING

!

To avoid serious injury or death:  

Always follow “Tractor Shutdown Procedure” provided in 
this manual before dismounting the tractor.

Cutter drive components are protected from shock loads 
by either a two plate friction clutch or a shear bolt. The 
shear bolt is designed to shear off when the blade 
impacts objects that the cutter is not designed to cut 
through. Avoid shear bolt failure by engaging the power 
take-off slowly at low engine rpm. Replace shear bolt & 
nylock nut with genuine Land Pride part numbers only. 
See available part numbers below. For installation 
instructions, refer to 

“Install Driveline” 

on page 13.

Clutch Run-In

Figure 4-3

Clutch Run-In

The clutch must be capable of slippage during operation 
to protect gearbox, driveline and other drivetrain parts. 
Friction clutches should be “Run-in” prior to initial 
operation and after long periods of inactivity. To protect 
driveline and gearbox, repeat “Run-In” instructions at the 
beginning of each season and when moisture and/or 
condensation seizes the inner friction plates.

Refer to Figure 4-3:

1.

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

2.

Carefully loosen each of the 8 spring retainer nuts by 
exactly 2 revolutions. It will be necessary to hold the 
hex end of the retainer bolt in order to count the exact 
number of revolutions.

3.

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

4.

Inspect the 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 disc and plate are still aligned. 

5.

Tighten each of the 8 spring retainer nuts on the 
clutch housing exactly 2 revolutions to restore the 
clutch to the original setting pressure.

6.

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

“Clutch Assembly”

 

to adjust for 

proper spring length.

Clutch Disassembly

Refer to Figure 4-4:

To disassemble the clutch, first remove the spring 
retainer nuts (#1), springs (#2), and bolts (#3) from the 
assembly. Each friction disc (#4) must then be separated 
from the metal surface adjacent to it. Inspect all parts for 
excessive wear and condition. Clean all parts that do not 
require replacement.

Clutch Disassembly

Figure 4-4

Inspection

Inspect all parts for excessive wear and condition. Clean 
all parts that do not require replacement.The original 
friction disc thickness is 1/8" (3 mm) and should be 
replaced if the thickness falls below 3/32" (2.4 mm). If the 
clutches have been slipped to the point of “smoking”, the 
friction discs may be damaged and should be replaced. 
Heat build-up may also affect the yoke joints. 

Clutch Assembly

Refer to Figure 4-4:

Reassemble each friction disc (#4) next to the metal plate 
it was separated from. Make certain the bushing is 
positioned as shown. Install bolts (#3) through the end 
plates and intermediate plates as shown. Place 
springs (#2) over the bolts and secure with nuts (#1).

IMPORTANT: 

If clutch run-in procedure indicated 

that one or more friction disks did not slip, the clutch 
must be disassembled to separate the friction discs.
