Lock valve

The lock valve is installed between the HST

charge pump and work equipment PPC valve.

As the work equipment lock lever is set to the

"Lock" position, this valve, in conjunction with

the work equipment lock lever, cuts off the oil

of the PPC circuit to disable the work equip-

ment operation.
