Test Procedure
Groundsmaster 360
16225SL Rev C
Perform the PTO pressure valve test if you identify a PTO engagement problem.
This test determines if the PTO pressure valve in the transmission is operating
correctly.
1. Ensure that the hydraulic fluid is at normal operating temperature.
Before opening the hydraulic system, operate all the hydraulic
controls to release system pressure and avoid injury from the
pressurized hydraulic fluid; refer to
Hydraulic System (page
g036034
2. Park the machine on a level surface, lower the cutting deck, shut off the
engine, and set the parking brake.
3. Read all Warning, Cautions, and precautions listed at the beginning of this
section.
4. Clean the transmission area around the pressure valve test port
Note: If the machine is equipped with optional speed reduction kit, a
hydraulic fitting and hose for the kit is connected to the transmission pressure
valve test port. For testing the PTO pressure valve, disconnect the hydraulic
hose and remove the fitting from the transmission port. Install a cap in the
speed reduction kit hose. Then, install the pressure gauge and proceed with
remaining steps of test. When the PTO pressure valve testing is completed,
install the fitting to the transmission port, remove the cap from the hydraulic
hose, and connect the hose to the fitting.
5. Remove the plug from the pressure valve test port
