Forward
When the HST pedal (10) is stepped on and in forward, so the variable swashplate (6) is tilted by the servo piston
(8) and regulator valve (11) as shown in figure above.
As the pump cylinder block (5) rotates with the input shaft (3), oil is forced out of pump port A at high pressure. As
pressure oil enters motor port D, the pistons, which align with port D, are pushed against the thrust plate and slide
down inclined surface.
Then the output shaft (21) rotates with the motor cylinder block (20). This drives the machine forward and the angle
of pump swashplate determines the output shaft speed.
As the motor cylinder block continues to rotate, oil is forced out of motor port C at low pressure and returns to the
pump port B.
