Caution
Before starting pressure measurement, make
sure that there are no people around the
machine.
Important
Use a pressure gauge and hydraulic hose
which can withstand the pressure of 28 MPa
(285.52 kgf/cm
2
) (4,060.91 psi) or more.
The reverse-side measurement port is
located in the rear cross-valve of the main
vehicle.
Follow the steps below to install the
pressure gauge for high pressure
measurements.
Remove the G1-port screw of the cross-
valve with a 3/8 hex key.

Apply resistance on the frame part using a
sling, etc. so that the main vehicle will not
reverse.
Note:
Keep the sling away from #1 mower unit.

Make sure that the parking brake is applied.
Start the engine, and rev it up to the
maximum rpm.
Release the parking brake.
Depress the reverse pedal, and it is normal
if the pressure becomes 24.5 MPa (250.25
kgf/cm
2
) (3,553.30 psi) with the tires locked
without slipping.
