NOTE: The groomer drive is located on the opposite
side of the cutting unit from the cutting reel motor. Figure

the left side of the cutting unit.
Disassembly (Fig. 6)
1. Park machine on a clean and level surface, lower
cutting units completely to the ground, stop engine, en-
gage parking brake and remove key from the ignition
switch.
2. To prevent unexpected reel motor operation, discon-
nect motors from the electrical power supply by unplug-
ging the 48 VDC battery disconnect (see 48 VDC
Battery Disconnect in the General Information section of
this chapter).
NOTE: If cutting unit is equipped with powered rear roll-
er brush, removal of roller brush components will be
necessary to replace groomer drive belt (see Rear
Roller Brush (Optional) in the Service and Repairs sec-
tion of Chapter 7 - Cutting Units).
NOTE: When removing groomer cover, groomer
weight does not have to be removed from cover.
3. Remove two (2) flange nuts that secure groomer
cover, then remove cover.
4. Remove groomer drive belt tension by pivoting idler
plate and pulley using a wrench on pulley nut. Slip
groomer drive belt off pulleys. Carefully release idler
plate and pulley.
5. As needed, remove drive pulley (item 5), driven pul-
ley (item 12) and idler pulley (item 10) using Figure 6 as
a guide.
NOTE: See Groomer Plate Assembly in this section for
information on removing and installing groomer plate
(item 21), pivot hub (item 22) or idler plate (item 23).
Assembly (Fig. 6)
1. If idler pulley (item 10) was removed, make sure that
bearings are in good condition before installing pulley.
Slide pulley assembly onto idler plate shaft and secure
with flange nut. Torque flange nut from 75 to 90 in- lb
(8.5 to 10.1 N- m).
NOTE: To prevent groomer shaft from turning when
installing driven pulley, use wrench on groomer shaft
flats.
2. If driven pulley (item 10) was removed, make sure
that spacer and washer(s) are on groomer shaft. Apply
antiseize lubricant to splines of drive pulley, slide pulley
onto groomer shaft and secure with flange nut. Torque
flange nut from 27 to 33 ft- lb (37 to 44 N- m).

NOTE: To prevent cutting reel from turning when instal-
ling drive pulley, block cutting reel with piece of wood.
3. If drive pulley (item 5) was removed, apply antiseize
lubricant to key slot in shaft. Place square key into shaft
slot. Slide drive pulley onto shaft and secure with flange
head screw. Torque screw from 27 to 33 ft- lb (37 to 44
N- m).
4. Check pulley alignment by laying a straight edge
along the outer face of the drive pulley (Fig. 7). Drive and
driven pulleys should be in line within 0.030" (0.76 mm).
If necessary, align pulleys by removing driven pulley and
installing or removing washer(s) (item 13 in Figure 6) be-
tween pulley and pulley spacer. Do not use idler pulley
to check pulley alignment.
5. Install drive belt to drive pulley, idler pulley and driven
pulley observing correct belt routing (Fig. 7). Make sure
that groomer drive belt is above idler pulley after belt in-
stallation and also that the ribs on drive belt are seated
in grooves in each pulley.
6. Install groomer cover and secure with two (2) flange
nuts.
7. Plug the 48 VDC battery disconnect back in before
operating the machine.
