Rear Roller - Toro 30821 Service Manual

Rear Roller

Three types of rear rollers have been used on the
Groundsmaster 3500--D. One roller design has sealed
bearings with no grease fittings on the roller shaft. The
second design has grease fittings in the roller shaft
ends. The third design has grease fittings incorporated
into the roller fasteners. Removal and installation of the
rear roller from the cutting deck is the same, regardless
of roller type.
Removal (Fig. 13)
1. Park machine on a level surface, lower cutting units,
stop engine, engage parking brake, and remove key
from the ignition switch.
2. If cutting deck is equipped with roller scraper, re-
move roller scraper from deck.
A. If equipped with early style roller scraper (Fig.
14), loosen one locknut that secures roller scraper
rod to mounting bracket.
B. Remove fasteners securing left and right scraper
rod brackets to roller mounts (Figs. 14 and 15).
C. Remove scraper rod assembly from cutting deck.
3. Remove four (4) mounting screws securing roller
mounts to rear of deck frame. Remove roller mounts and
rear roller assembly from deck frame.
4. Loosen fasteners securing each end of roller to roller
mounts. Remove mounts from roller.
Installation (Fig. 13)
1. Place roller assembly into roller mounts.
2. Install roller and roller mount assembly into rear of
deck frame. Secure assembly to deck frame with flange
head screws.
IMPORTANT: If roller design includes grease fittings in
roller fasteners (items 8 and 9 in Fig. 13), make sure the
grease groove in each roller mount aligns with the
grease hole in each end of the roller shaft. To help align
the groove and hole, there is also an alignment mark on
one end of the roller shaft.
3. Tighten fasteners that secure each end of roller to
roller mounts.
4. If equipped, install scraper rod assembly to roller
mounts. Adjust scraper rod (see Adjust Roller Scraper
in the Adjustments section).
5. If roller design allows greasing, lubricate roller
grease points.
