CENTER MOWER ASSEMBLY

1. Attach outboard bearing plate to cutterhousing.
FORWARD ROTATION (Bearing plate mounts on left side of cutterhousing.)
a. Secure with 3/8 NC x 7/8 Bolt and nut at front mounting hole. Torque to 35 ft.-lbs. (Typ.)
b. Secure with 3/8 NC x 2-1/4 Bolt, nut, lockwasher, and second nut at rear mounting hole. The Bolt is used as
an anchor for the idler arm spring.
REVERSE ROTATION (Bearing plate mounts on right side of cutterhousing)
a. Secure with 3/8 NC x 2-1/4 Bolt, nut and second nut at front mounting hole. The Bolt is used as an anchor
for the idler arm spring.
b. Secure with 3/8 NC x 7/8 Bolt and nut at rear mounting hole.
2. Install gearbox & extension shaft assembly and PTO shield mounting bracket
a. Remove existing nuts and lockwasher from bearing housing.
NOTE: On forward rotation units, remove only the lower two fasteners.
b. Slide bearing housing Bolt into proper holes in outboard bearing plate.
c. Attach gearbox and mounting bracket to gearbox mounting frame. Secure with 5/8 NC x 1-1/4 Bolt (upper
gearbox feet), and 5/8 NC x 1-1/2 Bolt (lower gearbox feet) and Lockwashers. Torque to 170 ft.-lbs. (Typ.)
d. Secure bearing housing to bearing plate with previously removed fasteners.
IMPORTANT: If extension shaft does not line-up with Gearbox, it may be necessary to shim gearbox mounting
lugs. To accomplish this, insert one gearbox retaining bolt (Figure 15) through the mount plate and into the
gearbox housing. Do not tighten this bolt (it should have at least 1/4" free threads to move in and out).
Assemble the gearbox, shaft, shaft extension tube and the bearing to the bearing retainer plate mounted on the
side sheet. Tighten all fasteners except the one bolt in the gearbox mounting plate. Check the distance
between the gearbox mounting lugs and the mount plate. If required, insert shims from shim kit (P/N 000552)
between gearbox mounting lugs and mounting plate to insure the gearbox pulls up evenly on the mounting
plate.
