The hydraulic system of the Groundsmaster 360 machine includes a solenoid
valve coil that is used to engage the PTO drive
valve coil is energized, hydraulic flow is directed to operate the PTO system.
The Toro Electronic Controller (TEC) provides current to the PTO solenoid valve
coil based on the position of several input switches.
Note: Do not remove the solenoid from the cartridge valve for testing.
1. Before you disconnect the PTO solenoid valve coil, test the solenoid and its
circuit wiring as TEC outputs with the InfoCenter display; refer to
InfoCenter Display for Troubleshooting (page
2. Raise the operator seat to get access to the PTO solenoid valve coil.
3. Ensure that the key switch is in the O
electrical connector from the solenoid valve coil.
Note: Before taking the small resistance readings with a digital multimeter,
short the multimeter test leads together. The multimeter displays a small
resistance value (usually 0.5 ohms or less). This resistance is because of the
internal resistance of the multimeter and test leads. Subtract this value from
the measured value of the solenoid coil that you are testing.
4. Measure the resistance between the 2 solenoid coil connector terminals of
the solenoid coil.
Note: The resistance of the solenoid coil must be approximately 7.5 ohms.
5. If the solenoid coil requires replacement; refer to
(page 5–104).
6. After you complete the testing, connect the wire harness connector to the
solenoid coil.
7. Lower and secure the operator seat.
