4. If installed, remove the rear roller brush drive shield
from the gear box.
IMPORTANT: Groomer gear boxes installed on the
left side of the cutting unit use a left hand thread.
Turn the input shaft (rear roller brush drive shaft)
clockwise to remove the gear box. Groomer gear
boxes installed on the right side of the cutting unit
use a right hand thread. Turn the input shaft coun-
terclockwise to remove the gear box.
5. Install a 5/16–18 X 5/8 inch square head set screw
(Toro p/n 1--803022) in the end of the drive shaft and
tighten to 13 N·m (120 in--lb); refer to Fig. 3.

adjustment rod at the front of the groomer gear box. Dis-

7. Tip up the cutting unit to access the bottom of the reel
to remove the drive shaft assembly.
8. Insert a long--handled pry bar (3/8 x 12 inch with
screwdriver handle recommended) through the bottom
of the cutting unit. The pry bar should pass between the
top of the reel shaft and the backs of the reel blades so
that the reel will not move.
IMPORTANT: To avoid grinding the reel, do not con-
tact the cutting edge of any blade with the pry bar as
this may damage the cutting edge and/or cause a
high blade.
9. Move the pry bar against the weld side of the reel
support plate closest to the groomer gear box.
IMPORTANT: You must use a 6--point socket with a
heavy wall to remove the gear box from the reel. Do
not use an impact wrench. Groomer gear boxes in-
stalled on the left side of the cutting unit use a left
hand thread; turn the drive shaft in correct direction
to remove the gear box.
10.Rest the handle of the pry bar against the front roller
and turn the drive shaft in correct direction to loosen it
from the reel. Continue to unscrew the drive shaft and
remove the gear box from the cutting unit.

aged during removal:
A. Remove the drain/fill plug and drain the oil from
the gear box.

the gear box cover assembly and driven gear. Re-
move and discard the cover gasket.
