INTRODUCTION
•
PTO clutch valve on the main body of the PTO clutch
as of the hydraulic wet multi-disc type can be turned
ON and OFF by the PTO switch control to discon-
nect and connect power to PTO.

If the PTO clutch is turned ON, auto or manual mode
can be selected. In case the PTO switch is turned
“auto” PTO power is automatically disconnected
when locating the hydraulic lift arm at up position
and in case the PTO switch is turned “manual” PTO
power is connected regardless of the position of
the hydraulic lift arm, as structured as convenient
for application according to the work conditions.
