Maintenance and Lubrication
Maintenance
Proper servicing and adjustment is the key to the long life
of any farm implement. With careful and systematic in-
spection, you can avoid costly maintenance, time and re-
pair.
For safety reasons, each maintenance operation must be
performed wiht tractor PTO disengaged, the cutter low-
ered completely to the ground or on safely supported
blocking, tractor engine shut off and ignition key removed.
1.
After using your cutter for several hours, check all
bolts to be sure they are tight.
2.
After transporting your cutter for several hours, check
all wheel lugs, bolts and nuts to be sure they are tight.
Always maintain proper air pressure in the tires.
Service Cutting Blades
1.
Both blades on each dishpan should be sharpened at
the same angle as the original cutting edge and must
be replaced or reground at the same time to maintain
proper balance in the cutting unit.
IMPORTANT: Replace blades with genuine Land Pride
blades only. If one blade is to be replaced, the mating
blade {on the same carrier} must also be replaced.
2.
Both blades on each dishpan should weigh the same af-
ter sharpening.
3.
When replacing or sharpening the cutter blades, exam-
ine bolts and hardware for excessive wear and replace if
necessary.
a.
Torque blade bolt lock nut to 450 ft. pounds. An ex-
tended cheater bar may be required to achieve
proper torque.
b.
Carefully check the cutting edges of the blades in re-
lation to the blade carrier rotation diagram below to
ensure correct blade placement.
!
CAUTION!
Installation of the longer blades on the wing decks will cause an
immediate operating hazard.
NOTE: Check tightness of bolts periodically, using
the “Torque Values Chart” on 24 as a guide.
NOTE: Do not remove any more material than nec-
essary when sharpening blades.
4.
Blade Dishpan Replacement:
Dishpan nut on gearbox output shafts should be torqued
to 450 foot/pounds and cotter pin installed in nut with legs
securely bent around nut.
Skid Shoe Service & Replacement
The center deck skid shoes should be checked periodical-
ly for wear and replaced is necessary. Order center deck
skid shoe Land Pride part #312-218H. No adjustment is
required.
!
CAUTION!
Skid shoe replacement must be done with the deck raised to the
transport position and securely blocked. Engage parking brake,
shut off tractor, remove key and disengage PTO before adjusting
or replacing these parts.
!
WARNING!
Excessive wear on skids may cause inadequate operation of cut-
ter and create a safety hazard!
The wing deck skid shoes should be checked periodically
for wear. Excessive leading edge wear can be repaired by
interchanging the LH wing skid with the RH wing skid. If
both leading edges have been worn down, order skid shoe
Land Pride part # 312-446H.
