Refer to Figure 5-2:
8.
Start by assembling blades without shim (#2). Insert
blade bolt (#1) through blade (#3), dish pan (#4) and
flat washer (#5). Temporarily secure blade with a
used nut (#6). Draw nut up snug. Do not tighten.
9.
Check blade deflection. If deflection is greater than
3/4", remove blade bolt and reassemble as before
except include shim (#2) when reassembling. Select
shim thickness based on deflection. The greater the
deflection, the thicker the shim.
10. Once blade deflection is correct, replace used nut
with new locknut (#6) and torque to 450 ft. lbs.
11. If replacing dishpan (#4), nut on gearbox output shaft
should be torqued to 450 ft-lbs. minimum and
secured with a cotter pin with both cotter pin legs
bent opposite directions around the nut.
Skid Shoe Maintenance
!
WARNING
Excessive wear on skid shoes can damage side panels, cause
inadequate operation of cutter, and create a safety hazard!
Always replace skid shoes at the first sign of wearing thin.
Skid shoes should be inspected at the beginning of each
cutting season and replaced when material thickness is
less than 1/8" at any point. Order only genuine Land
Pride parts from your local Land Pride Dealer.
Refer to Figure 5-3:
Replace skid shoes as follows:
1.
Raise the Rotary Cutter 3" or more off the ground
and place support blocks under the cutter. Make sure
the support blocks are positioned so they will not
interfere with skid shoe installation.
2.
Lower cutter onto the support blocks, place Skid
Steer in park, set park brakes, shut the Skid Steer off
and remove switch key.
3.
Remove 3/8" hex lock nuts (#4), lock washers (#5),
flat washers (#6), 3/8" plow bolts (#3), three skid
shoes (#1) and one skid shoe (#2) from all four deck
corners.
4.
Plow bolts should be checked for wear and replaced
if necessary.
IMPORTANT: Examine blade bolts (#1) and
washers (#3) for excessive wear and replace if worn.
IMPORTANT: Shim (#2) below may or may not be
required. If blade deflection is less than 3/4" without
a shim, then the shim is not required. A shim is
required if blade deflection is greater than 3/4".
IMPORTANT: Locknuts can loose their ability to
lock properly once removed. Always use a used
blade nut or plain nut in steps 8 & 9 below and then
replace used nut with new locknut in step 10.
