3.11 WHEELS STEERING LOCK SYSTEM

The trailer is equipped, as a standard, with a rear steering axle, passively steered. The axle
design allows for smoother cornering and easier maneuvering on marshy terrain, which
reduces machine tire wear. When reversing, the axle hubs must be locked, otherwise the
trailer will tend to turn uncontrollably to the left or right.
The axle can be locked by a single-line hydraulic system as shown in Figure (3.13). Before
driving backwards, extend the hydraulic steering lock cylinders (1) using the tractor distributor
lever.
The hydraulic connector of the turning lock system is marked with blue caps, as indicated on
the sticker (5).
