Cutter Blades
Always inspect cutting blades before each use. Make
certain they are properly installed and in good working
condition. Never try to straighten a bent blade. Small
nicks can be ground out when sharpening. For any blade
that is damaged, worn, bent, or excessively nicked,
replace with genuine Land Pride blades only. Refer to
page 49 and page 49 when ordering Land Pride
replacement blade components.
DANGER
!
To avoid serious injury or death:
•
Always disconnect driveline from the tractor before
servicing the drivetrain and components powered by the
drivetrain. A person can become entangled in the drivetrain
if the tractor is started and the power take-off is 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.
•
Wait for blades to come to a complete stop before accessing
blade bolts through blade bolt access hole.
•
Wear eye protection and gloves while inspecting, removing,
sharpening, and replacing a blade.

IMPORTANT:
Cutting blades must be replaced in
mating pairs. Not replacing both blades will result in
an out-of-balance condition that will contribute to
premature bearing breakdown on the spindle hub
and create structural cracks in the cutter housing.
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" (3 mm) and should be
replaced if thickness falls below 3/64" (1 mm). If clutches
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.
Assembly
Reassemble each friction disk (#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 the bolts and secure with nuts (#1).
Refer to Figure 5-7:
Progressively tighten each spring retainer bolt until
correct spring height “A” is reached.
