Manual Extract – Oil Flow
Oil is sucked into the charge pump through the a-port and pass through the HST filter. Then oil passes through the b-port and fed into the HST. Then oil is supplied to the main circuit of the HST as charge oil by means of the charge relief valve.
Oil from the b-port passes through the c-port and is supplied to the Hi-Lo solenoid valve. When the Hi-Lo solenoid valve is switched, the Hi-Lo spool is switched by the oil pressure of the main circuit of the HST. When the Hi-Lo solenoid valve is switched “ON”, the Hi-Lo spool is activated by the oil pressure of the main circuit of the HST.

When the Hi-Lo solenoid valve is switched “OFF”, the Hi-Lo spool is activated by the charge pressure. When the Hi-Lo spool is switched “ON”, oil on the high-pressure side (forward or backward) passes through the spool (pressure selector) and flows to the piston H (9).

Oil from the hydraulic pump is fed to the c-port of the regulator valve. The regulator valve sets the pressure of the PTO valve and proportional valve.
Oil from the regulator valve is guided to the servo piston by the motion of the proportional valve. The proportional valve is controlled by the operation of the HST pedal.
Oil from the regulator valve is supplied to the PTO valve and power steering controller.
