Clutch Assembly and Disassembly
Disassembly
Refer to Figure 4-3:
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 4-4:
Reassemble each friction disc (#4) next to the metal plate
it was separated from. Install bolts (#3) through end
plates and intermediate plates as shown. Place springs
(#2) over bolts (#3) and secure with nuts (#1).
Refer to Figure 4-4:
Progressively tighten each spring retainer bolt until
correct spring height “A” dimension is obtained.

IMPORTANT: Refer to Figure 4-4. Be Sure to
measure and record length (“A”) of each clutch
spring before disassembling clutch.

Cutter Blade Maintenance
!
DANGER
Always disconnect driveline from tractor PTO shaft before
servicing underside of cutter. If tractor is started with PTO
engaged, the cutter can cause bodily injury or death.
!
DANGER
Always secure cutter deck in the up position with solid
supports before servicing underside of cutter. Never work
under equipment supported by hydraulics. Hydraulics can
drop equipment if controls are actuated or if hydraulic lines
burst. Either situation can drop the cutter instantly even when
power to the hydraulics is shut off.
!
WARNING
Keep blade bolt access hole covered at all times except when
servicing cutter blades. Make sure driveline is disconnected
from the tractor before servicing cutter blades.
!
WARNING
Do not operate cutter with blades that are out-of-balance,
bent, excessively worn, excessively nicked, or with blade bolts
that are excessively worn. Such blades can break loose from
the cutter at high speeds causing serious injury or death.
!
WARNING
Do not attempt to straighten a bent blade or weld on a blade.
Do not attempt to modify a blade such as hard surfacing, heat
treating, cold treating, or by any other method. Always
replace blades with a new Land Pride blade to assure safety.
