Clutch Disassembly

If the clutch run-in procedure, (See

“Clutch Run-In”

page 25), indicated that one or more of the friction disks did

not slip, the clutch must be disassembled to separate the

friction discs.

Refer to Figure 5-2:

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.

Inspection

Inspect all parts for excessive wear and condition. Clean

all parts that do not require replacement.The original

friction disk thickness is 1/8" and should be replaced if

the thickness falls below 3/32". If the clutch have been

slipped to the point of “smoking”, the friction disks may be

damaged and should be replaced. Heat build-up may

also affect the yoke joints.

Clutch Assembly

Refer to Figure 5-2:

Reassemble each friction disk (#4) next to the metal plate

it was separated from. Make certain all bushing are

replaced in the same location as when removed. Install

bolts (#3) through end plates and intermediate plates as

shown. Place springs (#2) over the bolts and secure with

nuts (#1).

Refer to Figure 5-3:

Progressively tighten each spring retainer bolt until

correct spring height (“A” dimension) is reached.

Clutch Disassembly

Figure 5-2

IMPORTANT: Refer to Figure 5-3.

Be Sure to

measure and record length (“A”) of each clutch

spring before disassembling clutch.

Cutter Blade Maintenance

DANGER

To avoid serious injury or death:

•

Always disconnect driveline from power take-off shaft

before servicing underside of cutter. The tractor can be

started with power take-off engaged.

•

Always secure equipment with solid, non-concrete supports

before working under it. Never go under equipment

supported by concrete blocks or hydraulics. Concrete can

break, hydraulic lines can burst, and/or hydraulic controls

can be actuated even when power to hydraulics is off.

WARNING

To avoid serious injury or death:

•

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

at high speeds.

•

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 new Land Pride blades

to assure safety.

Always inspect cutting blades before each use. Make

certain they are properly installed and are in good

working condition. Replace any blade that is damaged,

worn, bent, or excessively nicked. Never try to straighten

a bent blade! Small nicks can be ground out when

sharpening.
Remove cutting blades and sharpen or replace as

follows:
1. Place tractor gear selector in park and/or set brakes,

shut engine off, and remove ignition key.

30559

A = Measured length of each spring
before disassembling slip clutch.

Use 1 3/32" for “A” dimension if
measurements were not taken.

IMPORTANT:

Only replace cutting blades in pairs

with genuine OEM blades. Replacing single blades

can result in an out-of-balance condition that will

contribute to premature bearing wear/breakage and/

or structural cracks in gearbox and/or deck.
