Adjusting the Counterbalance
Pressure
The counterbalance test port is used to test the
pressure in the counterbalance circuit (
The recommended counterbalance pressure is
2241 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 and
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.
