2.4 OPERATION CONTROL
2.4.1 NEUTRAL (HST PEDAL: STOP)
When the swash plate control lever is at neutral position,
the sliding surface of the swash plate will have vertical
position against piston. Then the cylinder block rotates
with input shaft but the piston stroke becomes zero.
Accordingly, the output shaft does not rotate because
the pump does not discharge oil and the motor does
not rotate.
