The counterbalance springs help balance the cutting units to
allow equal amounts of weight (down pressure) to be
distributed to each end of the cutting unit. The springs also
transfer weight from the cutting units to the traction unit
therefore, increasing traction.
The following are recommended settings for the
counterbalance springs. Minor changes may be required to
achieve optimum performance for your turf conditions. The
weight, at each end of the cutting unit, can be checked
easily with a spring scale.
• Increasing the spring tension reduces the weight on
inboard end of the cutting unit and increases the
weight on the outboard end.
• Decreasing the spring tension increases the weight on
the inboard end of the cutting unit and reduces the
weight on outboard end.

1. Hook the spring into the third hole from the top on the
inboard side of both front cutting unit lift tabs and on
the rear cutting unit lift tab (Fig. 12).
Note: Selecting the #4 hole position (increasing the spring
tension) will reduce the weight on the inboard end of the
cutting unit, increase the weight on the outboard end of the
cutting unit, and increase traction. Selecting the #2 hole
position has the opposite affect.

2. Secure the other end of the spring to the appropriate
hole (see below) on the front and rear counterbalance
arms (Fig. 13 & 14) with the spring shackle, clevis pin,
and cotter pin.
• Fourth hole from the top for 5 blade reels
• Third hole from the top for 8 blade reels
• Top hole for reels with baskets
Note: On the rear counterbalance spring, install the vinyl
cover over the spring before installing.
Note: Increasing the spring tension will reduce the weight
on the inboard end of the cutting unit, increase the weight
on the outboard end of the cutting unit, and increase
traction. Decreasing the spring tension has the opposite
affect.

3. Insert the breaker bar into the square hole in the
counterbalance arm and pivot the arm back to its
original position, aligning the mounting holes.
4. Secure the bottom of the counterbalance arm to the
frame with the capscrew and nut previously removed.
Tighten the top capscrew (Fig. 13).
5. To tension the counterbalance springs, proceed as
follows:
A. Remove the cotter pin and clevis pin securing the
spring shackle to the counterbalance arm. Do not
remove the other clevis pin.
B. Move the shackle up or down on the counterbalance
arm until it is aligned with the desired hole on the
arm. Install the clevis pin and cotter pin.
