Adjusting the Counterbalance
Pressure
No Parts Required
Procedure
For best performance, the cutting unit bounce on
uneven turf is minimal and it does not ride heavily over
flat terrain. If scalping occurs or the cut is uneven from
side to side, there may be too much weight on the deck
and the weight may have to be transferred to the traction
unit: i.e. increased counterbalance pressure.
By contrast, if too much weight is transferred to the
traction unit, the deck will bounce excessively and the
cut will be uneven. If the cutting unit does not perform
properly, adjust the counterbalance pressure as follows:
1. Ensure the parking brake is set, the PTO switch is
in OFF position and the lift lever is in the FLOAT
position.
2. Connect a pressure gauge to the test port behind the
right lift cylinder (Figure 12).
