Maintenance
Proper servicing and adjustment is the key to the long life
of any implement. With careful and systematic
inspection, you can avoid costly maintenance, time and
repair.
After using your cutter for several hours, check all bolts
to be sure they are tight.
Replace any worn, damaged or illegible safety labels by
obtaining new labels from your Land Pride Dealer.
!
DANGER!
Always disconnect main driveline from tractor PTO before
servicing the underside of the cutter deck. Cutter can be
engaged if tractor is started resulting in damage to the cutter,
bodily injury and/or death.
!
WARNING!
Always secure cutter deck in the up position with solid supports
before servicing the underside of the 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.
Service Cutting Blades
6. Always disconnect main driveline from tractor PTO
and secure cutter deck in the up position with solid
supports before servicing the underside of the cutter.
7. 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. Small
nicks can be ground out when sharpening.
8. Both blades should be sharpened at the same angle
as the original cutting edge and must be replaced or
re-ground at the same time to maintain proper
balance in the cutting unit. The following precautions
should be taken when sharpening the blades:
a. Do not remove more material than necessary.
b. Do not heat and pound out a cutting edge.
c. Do not grind blades to a razor edge. Leave a blunt
cutting edge approximately 1/16” thick.
d. Always grind the cutting edge so that the end of the
blade remains square to the cutting edge and not
rounded.
e. Do not sharpen the back side of the blade.
IMPORTANT: Blades must be ordered and replaced
in pairs. Order only genuine Land Pride blades.
Land Pride blades are made of special heat treated
alloy steel. Substitute blades may not meet Land
Pride’s specifications and may be dangerous to
operate.
f. Both blades should weigh the same after
sharpening with not more than 1 oz. difference.
9. Make certain when installing cutter blades that the
blades on one spindle is positioned 90 degrees to the
blades on the other spindle as shown in Figure 4-1.
10. Examine blade bolts for excessive wear and replace if
necessary. To replace blade bolts:
a. Order Land Pride blade bolt part #802-277C and
lock nut #803-170C.
b. Refer to Figure 4-1. Carefully check the cutting
edges of the blades in relation to the blade carrier
rotation to ensure correct blade placement.
c. Torque blade lock nut to 450 ft. pounds. An
extended cheater bar may be required.
