TOW BAR

The tow bar is vertically adjustable with
the hydraulic system lifting mechanism
within the whole range of the stroke. The
tow bar may only be coupled to those
agricultural implements that load it per-

The admissible vertical load is 5 kN for
the simple version of the tow bar, and
8 kN for doubled (reinforced) version of
the tow bar.
For the operation with the tow
bar, remove the multi-stage hitch
