2.6 AUXILIARY CONTROL VALVE (IF EQUIPPED)

A double acting detent type control valve is used. When
the control valve operating lever is moved to the imple-
ment cylinder actuating position, the spool is moved
and the oil from the pump port flows through A or B,
causing the implement cylinder to operate.
The return oil from the implement cylinder flows out of
the port A or B and returns to the transmission case.
This detent type valve can be used for the hydraulic
motor which needs to be supplied with the hydraulic
pressure continuously. However, if this valve is oper-
ated unintentionally or unnecessarily with the imple-
ment detached, the main relief valve opens which leads
to power loss and system damage due to overheated
hydralic oil.
