Hydraulic Brakes

(see Parts Manual section: Hydraulic Brakes)

(see Operator Manual section: Brake Operation)

Refer to Figure 118

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.
