HITCHING AND UNHITCHING THE SECOND TRAILER

A second trailer may only be hitched if it is a machine built on a dual axle chassis and if it

fulfils all requirements specified in section 1. Hitching the second trailer to the tractor - trailer

unit requires experience in driving an agricultural tractor with a trailer. While hitching the

second trailer, it is recommended to use the help of another person to guide the tractor

driver.

DANGER

When hitching, there must be nobody between the trailers. Person assisting in hitching
the machines should stand outside the area of danger and be visible to the tractor driver
at all times.

Hitching the second trailer

ATTENTION

Only double axle trailers may be hitched to the trailer.

Do NOT connect a second trailer with maximum total weight exceeding 18 000 kg.

Position the tractor with the first trailer hitched directly in front of the second

trailer's drawbar.

Immobilise the second trailer with parking brake.

Remove pin from the hitch of the first trailer.

If the trailer is equipped with automatic rear hitch, lift the pin by the

handle (3) - figure(4.2).

Adjust the height of the drawbar of the second trailer in such a manner to

enable coupling the machines.
