3.9 Safety in traffic
Driving on public roads with the towed machine without attached spreading unit is prohibited
(underride protection).
When traveling on public roads and tracks, the tractor with the towed machine and attached spreading
unit must comply with the traffic regulations of the country in which it is operating. The owner and
driver are responsible for compliance with these regulations.
3.9.1 Checks before driving
The check before departure is an important contribution to road safety. Before every trip, check
compliance with the operating conditions, traffic safety, and the regulations of the country of operation.
• Is the admissible overall weight complied with? Observe the admissible towing load and static
load of the trailer unit as well as the admissible axle load.
• Note the permitted brake load, the permitted tire load capacity load, and the permitted tire
pressure.
• Is the machine coupled correctly?
• Can fertilizer be lost while traveling?
○ Observe the filling level of the fertilizer in the hopper.
○ The metering slides must be closed.
○ Switch off the electronic control unit.
• Check the tire pressures and the function of the machine brake system. Observe the admissible
brake load and tire payload.
• Does the brake system setting correspond to the machine's load? See 6.6.7.1 Setting the manual
brake force regulator.
• Is the hopper cover closed and secured against accidental opening?
• Do the lighting and labeling on the machine comply with the national regulations for operation on
public roads? Make sure that warning signs, rear reflectors, and auxiliary lights are correctly
placed.
3.9.2 Road travel with the machine
Handling, steering, and braking performance of the tractor are affected by the towed machine. For
example, an excessive support load of the machine will reduce the weight on the front axle of the
tractor and affect the steering.
• Adapt your driving to the modified driving characteristics.
• When driving, always ensure that there is sufficient visibility. If vision is restricted (e.g., when
reversing), another person is required to direct the driver.
• Observe the admissible maximum speed.
• Avoid sudden turns when driving uphill or downhill or across a slope. The change in the center of
gravity may increase the danger of tipping. Special care is to be particularly applied when driving
on uneven, soft ground (e.g., when entering fields, curbs).
• Passengers are prohibited on the machine during transport and operation.
• If necessary, attach a front weight at the tractor. For further information, please refer to the
operator’s manual of the tractor.
