WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure all hydraulic fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
• Keep your body and hands away from pin
hole leaks or nozzles that eject high pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic leaks.
• Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
• Get immediate medical help if fluid is injected
into skin.
Changing the Counterbalance
Settings
During different times of the mowing season or when turf
conditions vary, the amount of counterbalance (upward lift)
required on the cutting decks can be changed to meet the
conditions.
1. Position the machine on a level surface, lower the
cutting decks, stop the engine, engage the parking
brake, and remove the key from the ignition switch.
2. Unlatch and remove the access panel from the side of
the control arm.
3. Locate the two capped counterbalance jumper wires
inside the compartment (Figure 55).

4. With the key in the OFF position, remove the cap from
jumper wires and plug the wires together (Figure 56).
2. Wire cap
5. Turn the key to the RUN position but DO NOT start
the machine.
6. The current counterbalance setting will flash on the
diagnostic light. The system allows for 3 settings. The
machine is set at the factory in position 2.
7. The counterbalance setting is changed by using the
Raise-Lower Joystick. To change the counterbalance
setting proceed as follows:
•
Moving the joystick forward to the lower position
and releasing it will lower the counterbalance
setting, thus increasing the effective weight of each
cutting deck in the turf
•
Moving the joystick rearward to the raise position
and releasing it will increase the counterbalance
setting, thus decreasing the effective weight of each
cutting deck in the turf
•
After the joystick is released, the diagnostic light
will flash the new counterbalance setting (1, 2, or 3).
8. When the desired setting is attained, rotate the key to
the Off position.
9. Unplug the jumper wires, install the cap on the wires
and put the wires back into the compartment.
10. Replace and latch the access cover.
Note: The machine cannot be operated while in the
counterbalance adjustment mode. Once the adjustment
has been completed, move the machine to a test area
and operate the machine with the new setting. The
new counterbalanced setting may change the effective
height of cut.
Hydraulic System Test Ports
Use the hydraulic system test ports to test the pressure in
the hydraulic circuits. Contact your local Toro distributor for
assistance.
