Brake Hook-up (Option)
Two drill braking (trailer braking) systems are available:
• Dual-line air system (Figure 8), and
• Single-line hydraulic (Figure 9).
In both systems, the tractor’s trailer brake remote port(s)
operate a hydraulic slave cylinder on the drill.
Tractor trailer braking systems are normally integrated
with the tractor brakes, and operate the trailer brakes
when tractor brakes are used during tractor movement.
The trailer braking system may or may not be integrated
with the tractor parking brake system.
Trailer brakes typically are not automatically engaged
when the tractor transmission is in Park, and may not be
engaged by any tractor Emergency Brake.
Braking Hazards:
Make sure the operator understands when drill brakes are
engaged and when they are released (make a record of tractor
behaviour on page 44).
Also understand and comply with tractor operational
restrictions when trailer brakes are used. For example, it is
generally necessary to inter-tie split brakes, and avoid
differential (steering braking) if trailer brakes are used.
