Adjusting The Lift Arms - Toro 30821 Operator's Manual

Adjusting the Lift Arms

1. Start the engine, raise the decks, and check to make sure
that the clearance between each lift arm and the floor
plate bracket is .18–.32 in. (5–8 mm) (Fig. 10). If the
clearance is not in this range, back off the stop bolts
(Fig. 11) and adjust the cylinder to attain clearance. To
adjust the cylinder, back off the jam nut on the cylinder
(Fig. 12), remove the pin from the rod end, and rotate
the clevis. Install the pin and check the clearance.
Repeat the procedure if required. Tighten the clevis jam
nut.

2. Check to make sure that the clearance between each lift
arm and stop bolt is 0.005–0.040 in. (0.13–1.02 mm)
(Fig. 11). If the clearance is not in this range, adjust the
stop bolts to attain clearance.

3. Start the engine, raise the decks, and check to make sure
that the clearance between the wear strap on the top of
the rear cutting unit wear bar and the bumper strap is
0.02–0.10 in. (0.51–2.54 mm) (Fig. 13). If the clearance
is not in this range, adjust the rear cylinder to attain
clearance. To adjust the cylinder, lower the cutting units
and back off the jam nut on the cylinder (Fig. 14).
Grasp the cylinder rod close to the nut with a pliers and
rag and rotate the rod. Raise the cutting units and check
the clearance. Repeat the procedure if required. Tighten
the clevis jam nut.
Note: If the rear lift arm "clunks" during transport,
clearance can be reduced.
