The suspension system frame (1) is used to connect the mower with the tractor. The main frame (4) is connected piv-
otally with the suspension frame through the central beam (2). The cutting system is made of two operating drums
(7) with blades attached rotationally in their lower part. The drums rest on the stump jumpers (8) when in the operat-
ing position, which adjust to the ground contours.
Changing the position of the mower from the transport position to the operating position and backwards is made pos-
sible through the pivotal connection of the of the suspension system frame with the central beam. The guards and
shield (8) protect the machine operator and other people from any hard object, which might be thrown out from under
by the operating drums (7).
The spring fuse prevents damages of the mower when the cutting system moves onto an obstacle; the operating drums
are powered by the tractor's PTO. The drums along with the blades rotate in opposite directions cutting the forage
and forming it into windrows.
The slip one way clutch allows for free movement of the drums after disengaging the engine and protects the drive
elements from any damage.
