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.
