material and automatic lifting by the
pick-up.
1.2.7 General Technical Data
• Road driving is permitted only when the bale chamber
is empty and closed.
• Permissible top speed: 40 km/h / 30 km/h
• For machines which have no brakes, the pulling
tractor's tare weight must correspond with the
permitted operating specifications, or at least have a
weight which corresponds with the baler's tare weight.
• For machines which have an operating permit, follow
the conditions contained therein!
• When operating the baler in the field, a supporting
load of 600 kg (on the ring hitch) should not be
exceeded.
• Switch off the electrical operating control when driving
on roads!
The tailgate must only be operated if
the baler is attached correctly to the
tractor. If this is not respected there is a
risk of tipping to the rear.
