[B] Unload Valve Linkage
When starting from a stopped position on a slope
(the brake pedal (1) is not depressed), due to residual
pressure in the HST circuit, shifting to the neutral
position cannot always be fully achieved.
This time, to eliminate this problem, an unload valve
is employed in the travel circuit.
When the brake pedal (1) is depressed, the unload
valve opens and the residual pressure in the travel circuit
is relieved the orifice.
