Removing Blades

(Figure 11)
NOTICE
■
If blade pin (1) is seized in crossbar and extreme
force will be needed to remove it, support crossbar
from below to prevent gearbox damage.
1. Disconnect driveline from tractor PTO.
2. Open blade access cover and align crossbar (3)
with blade access hole in the cutter frame. Remove
nut (5), top blade if installed, and bushing (4) from
blade pin. Drive pin (1) out of crossbar (3).
3. Rotate crossbar (3) and repeat for opposite blade.

Installing Blades

CAUTION
 Your dealer can supply genuine replacement
blades. Substitute blades may not meet original
equipment specifications and may be dangerous.
NOTICE
■
Crossbar rotation viewed from the top of the
cutter, is counter-clockwise for the right gearbox
and clockwise rotation on the left gearbox; the cen-
ter crossbar is counter-clockwise on the 540 rpm
models and clockwise on the 1000 rpm models. Be
sure to install blade cutting edge to lead in correct

NOTE: Always replace or sharpen both blades at the
same time.
1. Inspect blade bolt (1) and bushing (4) for nicks or
gouges. Replace blade bolt if any defects are
found, Always replace lock nut (5) when changing
blades.
2. Insert blade pin (1) through blade (2), align key on
blade pin with keyway in crossbar, and push blade
pin through crossbar.
3. Install upper blade, if using shredder kit, and
bushing (4). Place a few drops of oil on pin and
torque nut to 644 lbs-ft.
4. Repeat steps for opposite side.
NOTE: Blade should be snug but should swivel on
pin without having to exert excessive force. Oper-
ating cutter when blades do not freely swing will
cause excessive vibration.

Sharpening Blades

NOTICE
■
When sharpening blades, grind the same
amount on each blade to maintain balance.
Replace blades in pairs. Unbalanced blades will
cause excessive vibration, which can damage
gearbox bearings. Vibration may also cause struc-
tural cracks to cutter.
1. Sharpen both blades at the same time to maintain
balance. Follow original sharpening pattern.
2. Do not sharpen blade to a razor edge—leave at
least a 1/16" blunt edge.
3. Do not sharpen back side of blade.
