Adjust Front Lift Arms - Toro Groundsmaster 3500 30807 Service Manual

Adjust Front Lift Arms

1. Park machine on a level surface, fully raise cutting
units, stop engine, engage parking brake, and remove
key from the ignition switch.
IMPORTANT: Keep front cutting units on the lift
arms when performing this adjustment.
2. Make sure clearance between each lift arm and floor
plate bracket is from 0.18 to 0.32 inch (4.6 to 8.1 mm)
(Fig. 4).
3. If the clearance is not in this range, attain proper
clearance as follows:
A. Lower front lift arms, stop engine, engage parking
brake, and remove key from the ignition switch. Back
off stop bolts if reducing the clearance between the
lift arm and the floor plate bracket (Fig. 5).
B. Adjust front hydraulic cylinder by backing off jam
nut on the cylinder, removing the pin from the clevis,
and rotating the clevis (Fig. 6).
C. Install pin to clevis. Fully raise front lift arms and
check clearance. Repeat steps A and B if necessary.
D. Tighten jam nut on the hydraulic cylinder when
clearance is correct.
IMPORTANT: The lack of clearance at the front
stops can damage the lift arms.
4. With the front lift arms fully raised, make sure clear-
ance between each lift arm and stop bolt is from 0.005
to 0.040 inch (0.13 to 1.02 mm). If the clearance is not
in this range, adjust stop bolts as necessary (Fig 5).
