Figure 1-15 Sequence of Operation - BRAKE-ON

Sequence of Operation, BRAKE-ON

The directional control valve spool is spring centered to
neutral. In this position, the motor work ports are open to
the tractor reservoir and pump standby supply pressure
is blocked. Pilot control pressure is available at the logic

control manifold and the control lever. There is no pressure
on the control lines which are open to the tractor reservoir.
Similarly, there is no pressure in the load sense line as it
is vented back to the tractor reservoir through an orifi ce.
