Maintenance
Proper servicing and adjustment is the key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly down time and repair.
Check all bolts after using unit for several hours to be
sure they are tight. Replace any worn, damaged, or
illegible safety labels by obtaining new labels from your
Land Pride Dealer.
The parts on your cutter have been specially designed
and should only be replaced with genuine Land Pride
parts. Do not alter the cutter in a way which will adversely
affects its performance.
Cutter Blade Maintenance
!
DANGER
Always disconnect main driveline from tractor PTO before
servicing underside of cutter. PTO can be engaged if tractor is
started causing in damage to cutter, 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 bent, out of balance,
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.
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.
IMPORTANT: Replace cutting blades with genuine
Land Pride blades only. Blades must be replaced in
mating pairs. Not replacing both blades will result in
an out-of-balance condition that could contribute to
premature bearing wear/breakage and/or structural
cracks in gearbox and/or deck.
Remove cutting blades and sharpen or replace as
follows:
1.
Place skid steer in park and/or set brakes, shut
engine off and remove ignition key.
2.
Always disconnect hydraulics from Skid Steer and
secure cutter deck in the up position with solid
supports before servicing underside of cutter.
3.
Refer to Figure 5-1: Remove access cover.
4.
Refer to Figure 5-2: Rotate blade bolt (#1) until in
alignment with access hole.
5.
Unscrew locknut (#6) to remove cutting blade (#3).
Blade bolt (#1) is keyed and will not turn freely.
6.
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 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 cutting edge so end of blade
remains square to cutting edge and not rounded.
e. Do not sharpen back side of blade.
f. Both blades should weigh the same with not more
than 1 1/2 oz. difference. Unbalanced blades will
cause excessive vibration which can damage
gearbox bearings and create structural cracks.
7.
Refer to Figure 5-1: Carefully check cutting edges of
blades in relation to blade carrier rotation to ensure
correct blade placement. Blade rotation is clockwise
with cutting edge leading. Airfoil (lift) must be
oriented towards the top of the deck.
