The round baler guarantees the highest performance in forming the souring fodder, hay and straw into compact round bales, it is characterized by reliability and comfort of operation. Formation of bales takes place in press chamber equipped with 17 specially profiled drums. The large number of compressing drums of small diameter ensures a very effective bale compression at low power requirement. The round baler performance depends also on the way the bales are bound. The automatic lubrication of chains increases the operation comfort and the overall machine performance. Operating the machine becomes an game using the pilot box enabling the control of the most of machine functions, including the net binding from the tractor cab. The system signalizes acoustically and optically the overall condition of the machine. The automatic lubrication of the chains with vegetable oil increases the durability of the machine and is ecologically safe.
