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.
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.
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.
