CHANGING TO FORWARD OR REVERSE ROTATION

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 deg. 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.

To change direction of cuttershaft rotation for the rear mover, three left hand 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.

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 existin g kn ive s, re mo ve an d disc ar d th es e pin s an d ins tall new kniv es using new

pins. Figure ASM-FL-0047

FOR FORWARD ROTATION: On the right wing and rear 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 rear unit, all knife pins must be installed with their heads

facing toward the cuttershaft pulley. On the left wing, and rear un it, the head s of th e knife pin s must fa ce away

from the cuttershaft pulley.
