Brake Operation (option)
Implement wheel brakes are optional. There are brake
shoe pairs on each of the outside transport wheels. The
shoe pairs are operated by two independent systems:
1. The “service” or “trailer brake” system is controlled
by the tractor. It is connected to the tractor with a
single hydraulic line or two air lines.
2. The implement can be parked by manually placing
chock blocks on either side of the transport tires.

Brake Roll-Away Hazard:
Set manual chock blocks before unhitching implement. Block
tires if brakes are not installed, and for extra safety in case
brake system is tampered with or is not in working order.
Parking jack is not sufficient restraint for a implement parked
on un-level ground. An unsecured implement. could roll away,
causing an accident resulting in death, injury and substantial
property damage.
Both versions of the trailer brake system to the tractor are
spring-release on the implement. Unless the chock blocks are
set, implement service braking is released shortly after
unhitching the implement.
Note: The wheel chock system is not a true emergency
brake system, as there is no safe way to set the
chock blocks when the implement id in motion.
This manual therefore refers to it only for parking.
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 implement.
Know Your Tractor Systems:
Application of tractor Parking and/or Emergency brakes may
or may not operate the implement 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. Note any vari-
ance from general behaviour in the table at right. Make
sure the tractor operator knows when implement brakes
are engaged and released.
Machine Damage Risk:
Make the implement chock block removal part of your trans-
port check-list. The tractor cannot place the chock blocks in
the transport position. Transporting with chock blocks in the
park position will result in tire or chock block damage.
