1 Introduction 1.1 General Information 67077 Excess-width machines In case of excess-width self-propelled working machines (width exceeding 3 m across tyres), an indi- vidual operating permit based on an individual expert's opinion, a special approval according to § 70, sect. 1 of the German Regulations Authorising the Use of Vehicles for Road Traffic and a special approval according to § 29 of the German Regulations Authoris- ing the Use of Vehicles for Road Traffic must be carried along. All conditions and notes specified there must be observed.
Especially the information regarding the marking of excess-width road vehicles must be com- plied with (two red/white marker boards each at the front and rear, two amber flashing warning beacons). The granting of the special approval and permits is subject to different regulations in every Federal State. Information can usually be obtained from your road traffic authorities in charge. Additional weights Self-propelled machines with rear axle steering and fit- ted with front attachments approved by CLAAS must be equipped with additional weights on the rear axle when driving on public roads.
This is required in order to prevent the machine from lifting off at the rear when braking and on slopes and to maintain the steering function. The required additional weights can be made up of implements, rear axle weights and liquid filling in the rear axle tyres. Depending on the type of front attachment and the equipment fitted to the machine, the rear of the self- propelled machine must be ballasted. Detailed information on this matter can be obtained from CLAAS.
Modifications to the machine When parts of the machine whose condition is pre- scribed are subsequently modified or installed, the operation of which may endanger other road users, the Operating permit (individual operating permit) and the special approval expire. To obtain a new individual operating permit, it is neces- sary to present the machine to the responsible technical inspection agency (TUEV, DEKRA) in order to prepare an individual expert's opinion according to § 19 of the German Regulations Authorising the Use of Vehicles for Road Traffic. If you are in any doubt as to whether this situation applies in your case, please contact CLAAS as the manufacturers.
