Reelmaster 3100−D Page 7 − 11 Cutting Units
Adjust Front Lift Arms
1. Park machine on a level surface, lower 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. Raise front lift arms. Make sure clearance between
each lift arm and floor plate bracket is 0.18 to 0.32 inch
(4.6 to 8.1 mm) (Fig. 10).
3. If the clearance is not in this range, attain proper
clearance as follows:
A. Back off stop bolts if reducing the clearance be-
tween the stop bolt and lift arm (Fig. 11).
B. Adjust front hydraulic cylinder by backing off jam
nut on the cylinder, removing the pin from the clevis,
and rotating the clevis (Fig. 12).
C. Install pin to clevis and check clearance. Repeat
steps A and B if necessary.
4. Make sure clearance between each lift arm and stop
bolt is 0.005 to 0.040 inch (0.127 to 1.02 mm). If the
clearance is not in this range, adjust stop bolts as neces-
sary (Fig 11).
IMPORTANT: The lack of clearance at the front
stops can damage the lift arms.
5. Install both front cutting units to the lift arms (see Cut-
ting Unit Removal and Installation).
