4.
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 disc and plate are still aligned. A clutch that 
has not slipped must be disassembled to separate 
the friction disc plates. See “Clutch Assembly and 
Disassembly” 
on page 24.
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 
cutting and periodically each week. An additional set 
of scribe marks can be added to check for slippage. 
See Figure 5-4 to adjust spring length.
Clutch Assembly and Disassembly
Disassembly
See IMPORTANT NOTE above before disassembling 
clutch. After measuring and recording each spring length, 
remove spring retainer nuts (#1), springs (#2), and bolts 
(#3). Each friction disc (#4) must then be separated from 
the metal surface adjacent to it. Refer to the Parts Manual 
for a detailed parts breakdown.
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" (3.2mm) and should be 
replaced if thickness falls below 3/64" (1.1mm). If 
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. 
Assembly
Reassemble each friction disc (#4) next to the metal plate 
it was separated from. Install bolts (#3) through the end 
plates and intermediate plates as shown. Place springs 
(#2) over bolts (#3) and secure with nuts (#1). 
Progressively tighten each spring retainer bolt until 
correct spring height “A” dimension is obtained.

Skid Shoe Maintenance
!
WARNING
There are skid shoes mounted on the cutter sides. Check 
both skid shoes for wear and replace if necessary. Order 
only genuine Land Pride parts from your local Land Pride 
dealer.
1.
Remove 3/8" hex whiz nuts (#3), 3/8" plow bolts (#2), 
and skid shoe (#1) as shown. 
2.
Plow bolts should be checked for wear and replaced 
if necessary.
3.
Attach new skid shoe (#1) to cutter with existing 
3/8" plow bolts (#2) and secure with 3/8" hex whiz 
nuts. Tighten to the correct torque.
4.
Repeat on opposite side.
