Brake Hook-Up (Option)
Two drill braking (trailer braking) systems are available:
• Dual-line air system (Figure 8), and
• Single-line hydraulic system (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.
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 (record tractor behaviour
on page 52).
Also understand and implement 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.
Air Brake Hook-Up (Option)
