Adjusting the Cutting-Unit
Counterbalance
Rear Cutting Units
CAUTION
The springs are under tension and could
cause personal injury.
Use caution when adjusting the springs.
You can 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.
You 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).
Note:
To remove all counterbalance force, position
the long leg of the torsion spring below the capscrew,
washer, spacer, and locknut.
1.
Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off
the engine, and remove the key.
2.
Insert a tube or similar object over the long leg
of the spring, and lift the spring leg to relieve
pressure on the spacer (
).
Note:
Have another person help by lifting and
lowering the spring leg.
