Adjusting the Lift-Arm Counterbalance
Rear Cutting Units
CAUTION
The springs are under tension, and adjusting them could result in minor or moderate
personal injury.
Use caution when adjusting the springs.
Adjust the amount of counterbalance force applied to the rear cutting-units to help
compensate for different turf conditions, and to maintain a uniform height of cut in rough
conditions or in areas of thatch buildup.
Adjust counterbalance force of each torsion spring to 1 of 4 settings. Each increment
increases or decreases the counterbalance force on the cutting unit by 2.3 kg (5 lb). You can
position the springs at the back side of the first spring actuator to remove all counterbalance
(fourth position).
Note: To remove all counterbalance force, position the long leg of the torsion spring above
the shouldered stud.
1. Park the machine on a level surface, lower the cutting units, shut off the engine, engage
the parking brake, and remove the key.

2. Insert the long end of the counterbalance
spring
into a tube or similar object, and
pivot the spring around the shouldered stud
to the desired position.
3. Repeat step 2 for the other counterbalance
spring.
