Service Brake Operation:
If optional brakes are installed and connected, the
hydraulic/hydraulic or air/hydraulic systems automatically
work in conjunction with the tractor’s own brakes.
Application and release of tractor brakes during tractor
motion applies and releases the service brake system on
the drill.
Know Your Tractor Systems:
Application of tractor Parking and/or Emergency brakes may
or may not operate the drill service brake system, depending
on the design of the tractor systems.
Consult your tractor manual for details on when remote
brake ports are engaged and released.
Refer to Figure 119
Single-Line Hydraulic Brake Operation
In this system, a single hydraulic line
from the tractor
operates a de-intensifier cylinder on the drill, which is
coupled to the drill master cylinder . The drill 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.
