Single-Line Hydraulic Brake Operation

Refer to Figure 26

In this system, a single hydraulic line from the tractor

operates a de-intensiﬁer cylinder on the implement,

which is coupled to the implement master cylinder . The

implement brake hydraulic lines are separate from the

tractor’s line.

With the hydraulic/hydraulic system, braking is immedi-

ately available when the tractor hydraulic system is active.

Dual-Line Air/Hydraulic Brake Operation

Refer to Figure 27

In this system, the “supply” (yellow or blue coded) line

charges a reservoir air tank on the implement. The

“service” (red coded) line meters air from the

reservoir to a booster cylinder , which operates the

implement’s hydraulic brake lines .

Service Air Brakes Not Instantly Available:

Prior to movement, wait for the tractor air system to reach full

charge after implement hook-up. Tractor and implement reser-

voir tanks must be pressurized. implement service braking may

not be immediately available upon tractor hook-up with the air/

hydraulic system.
