3.
Start tractor and engage PTO drive for 2-3 seconds
to permit slippage of the 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.
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
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 on page 24 to adjust spring length.
Clutch Assembly and Disassembly
Disassembly
Refer to Figure 5-3:
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
Refer to Figure 5-4:
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).
Refer to Figure 5-4:
Progressively tighten each spring retainer bolt until
correct spring height “A” dimension is obtained.
IMPORTANT: Refer to Figure 5-4.
measure and record length (âAâ) of each clutchÂ
spring before disassembling clutch.

!
WARNING
Excessive wear on skid shoes can damage side panels, causeÂ
inadequate operation of cutter, and create a safety hazard.Â
Always replace skid shoes at the first sign of wearing thin.
There are skid shoes mounted on the cutter sides. CheckÂ
both skid shoes for wear and replace if necessary. OrderÂ
only genuine Land Pride parts from your local Land PrideÂ
dealer.
1.
Remove 3/8" hex whiz nuts (#3), 3/8" plow bolts (#2),Â
and skid shoe (#1) as shown.Â
2.
Plow bolts should be checked for wear and replacedÂ
if necessary.
3.
Attach new skid shoe (#1) to cutter with existingÂ
3/8" plow bolts (#2) and secure with 3/8" hex whizÂ
nuts. Tighten to the correct torque.
4.
Repeat on opposite side.
