that the oil sent from the hydraulic pump may become the

hydrostatic transmission.

 PTO Clutch “Engaged”
When the PTO clutch lever is set at the “Engaged”
position, the PTO clutch valve (6) rotates and form the oil
line to the PTO clutch pack.
Oil entering the clutch pack pushes the clutch piston

 PTO Clutch “Disengaged”
When the PTO clutch lever is set at the
“Disengaged” position, the PTO clutch valve (6) rotates
and close the oil passage to the PTO clutch pack. The
oil in the PTO clutch pack drained into the transmission
case (5). Thus the clutch piston (2) is pushed back by
the spring (9).
When the piston (2) is pushed back, the piston push
to the brake pressure plate (1) so as to stop the rotation
and drag of the PTO shaft (4).
