Trailer
Several factors affect the compatibility of a trailer.
The type of trailer that can be connected to the tractor depends, among other
things, on:
•
The braking power of the tractor.
•
Whether the trailer has brakes.
•
How much of the trailer weight is on the hitch.
•
Whether the trailer has one or more axles.
The total trailer weight is the load added to the empty trailer weight.
When loading the hitch, at least 20% of the tractor weight has to be on the front
wheels.
The maximum allowed wheel or hitch loading must not be exceeded.

Trailer air pressure brakes
When towing a trailer, you can increase the braking power with trailer air
pressure brakes.
The trailer air pressure brake system (extra equipment) is controlled by the
tractor brakes. The trailer brakes operate also when using the parking brake.

1. Brake line coupling with yellow cover
2. Pressurised air quick coupling
3. Brake line coupling with black cover
4. Container line coupling with red cover
On a two-hose system, the trailer is connected to two couplings:
•
Container line with a red cover
•
Brake line coupling with a yellow cover
On one-hose systems, the trailer is connected to the brake line coupling with a
black cover.
The Duo-Matic system has only one coupling to connect.
WARNING: If the pick-up hitch is worn out or otherwise damaged so
that the drawbar eye can come off the pick-up hitch, the hook must be
replaced.
