TURNING INTERLOCK HYDRAULIC SYSTEM
The trailer can be delivered with a passively
steered rear steering axle. Axle design
enables easier cornering and easier ma-
noeuvring on marshy terrain, due to which
there is less tyre wear on machine. The
steering arms must be locked when re-
versing, otherwise the trailer will tend to
turn uncontrollably to the left or right when
reversing.
The axle steering lock is enabled by the
2-line hydraulic system shown in figure

The steering lock is controlled from the
tractor cabin with the lever of the ex-
ternal selective control valve in the tractor.
Locking and releasing the lock takes place
by extending or retracting the hydraulic
cylinder piston rod (1). Hydraulic lines (2)
to connect with the tractor are equipped
with quick couplings - plugs (3) and se-
cured with plugs (4).
