CUTTERSHAFT REPLACEMENT
NOTE: It is recommended that cuttershaft bearing and housing assemblies be replaced when replacing
cuttershaft.
1. Place unit on the ground or securely support at a convenient height.
2. Remove cuttershaft bearing and cutter assemblies as outlined in above. After removing both assemblies,
the cuttershaft can be removed and a new one installed. It may be necessary to remove two sets of knives
nearest the drive end of cuttershaft.
3. Install new bearing and housing assemblies as outlined in Image Mnt-FL-0063.
Changing to Forward or Reverse Rotation
WING MOWER
The hydraulic wing motors are dual rotation motors which means they will rotate in either direction depending
on the inlet port used. An arrow on the flat surface of the motor housing at both ports indicate the direction of
rotation. To change rotation, remove the four bolts that mount the manifold block to the motor. Remove the
case drain hose at the motor, but leave it attached in present location at the manifold block. Leave all other
plumbing as presently installed at the manifold block. Remove the two mounting bolts at the motor mounting
plate and rotate the motor 180 degrees. This changes the present inlet port into the outlet port of the motor.
Re-install manifold block but do not change the position. Install case drain hose.
CENTER MOWER
To change direction of cuttershaft rotation for the center mower, three parts are required. A belt guard, an
outboard bearing plate and a idler pulley arm. (Consult parts book for these part numbers). Remove the
cuttershaft and turn 180 deg. remove the gearbox cuttershaft drive pulley and outboard bearing plate, (using
the proper bearing plate) mount the plate to opposite side of mower housing. Remove the four bolts that
mounts the gearbox and rotate gearbox 180 deg. to new position. Install cuttershaft pulley, gearbox output
pulley, idler arm pulley assembly and belt. REPLACE EXISTING BELT GUARD WITH PROPER GUARD.
Replacing Cutter Unit Knives
The cutter knives are attached to the cutter shaft with hardened pin and cotter pins. These pins are supplied
with the knife kit. To remove existing knives, remove and discard these pins and install new knives using new
pins. Mnt-FL-0059.
FOR FORWARD ROTATION: On the right wing and center unit, all knife pins must be installed with their
heads facing away form the cuttershaft pulley. On the left wing, the heads of the knife pins must face the
cuttershaft pulley.
FOR REVERSE ROTATION: On the right wing and center unit, all knife pins must be installed with their heads
facing toward the cuttershaft pulley. On the left wing, the heads of the knife pins must face away from the
cuttershaft pulley.
