BLADE SERVICING

BLADE REMOVAL (Figure 7)

2.Lockwasher

3.Blade beam

4.Blade

5.Blade bolt

Figure 7. Blade Installation

Disconnect driveline from tractor PTO.

It is necessary to gain access to bottom side of cutter for blade removal. Raise cutter and block securely.

Align crossbar (3) with blade access hole in the cutter deck. Remove nut (1) and lockwasher (2) then carefully drive bolt (5) out of crossbar.

IMPORTANT

If blade bolt (5) is seized in blade beam and extreme force will be required to remove it, support blade beam from below to prevent gearbox damage.

Rotate blade beam (3) and repeat for opposite blade. Always replace or sharpen both blades at the same

time.

Inspect blade bolt (5) for nicks or gouges; replace if any are found. Insert bolt through blade. Blade should swivel on bolt. Determine cause if it does not and correct.

Align blade beam (3) with blade access hole in the cut- ter frame. Apply a liberal coating of Never Seez® or equivalent to blade bolt and blade beam hole. Make sure blade is offset away from cutter.

IMPORTANT

Blade beam rotation is counter-clockwise when looking down on cutter. Be sure to install blade cut- ting edge to lead in counter-clockwise rotation.

Never Seez is a registered trademark of the

Never Seez Corporation.

Insert blade bolt (5) through blade, align key on blade bolt with keyway in blade beam and push blade bolt through blade beam. Insert lockwasher (2) and nut (1) through blade access hole in the cutter deck, install on bolt (5) and tighten to 350 lbs.-ft.

Repeat for opposite blade.

BLADE SHARPENING

IMPORTANT

When sharpening blades, grind each blade the same amount to maintain balance. Replace blades in pairs. Unbalanced blades will cause excessive vibra- tion which can damage gearbox bearings. Vibration may also cause structural cracks to cutter.

Sharpen both blades at the same time to maintain bal- ance. Follow original sharpening pattern. Do not sharpen blade to a razor edge, but leave at least a 1/16” blunt edge. Do not sharpen back side of blade.

SHEAR BOLT REPLACEMENT

IMPORTANT

Always use approved 1/2” NC x 3” grade 2 shear bolt as a replacement part. Using a hardened bolt or shear pin may result in damage to driveline or gearbox.

Remove driveline shield bell. (Refer to page 19 for instructions.)

Make sure the input shaft of the gearbox is greased. This reduces the chance of the PTO shaft yoke from galling to the input gearbox shaft if the shear bolt should break.

Rotate driveline to align holes in yoke and shaft. Install shear bolt and secure with locknut. Replace driveline shield bell.

W ARNING!

FAILURE TO USE CORRECT SIZE SHEAR BOLT MAY CAUSE PERSONAL INJURY OR DEATH.

W ARNING!

FAILURE TO INSTALL RETAINING CLIP WILL ALLOW DRIVELINE TO SWING FREELY IF BOLT IS SHEARED CAUSING POSSIBLE INJURY OR DEATH.
