Adjusting the Counterbalance
Pressure
The counterbalance test port is used to test the pressure in
the counterbalance circuit (
). The recommended
counterbalance pressure is 2,241 kPa (325 psi). To adjust
the counterbalance pressure, loosen the locknut, rotate the
adjusting screw (
) clockwise to increase the pressure,
or counterclockwise to decrease the pressure and tighten the
locknut. The engine must be running, the deck lowered and
in the float position to check the pressure.
Note:
The caster wheels of all 3 mower decks should remain
on the ground when adjusting the counterbalance and with
counterbalance applied.
