3-point linkage frame (1) enables attachment of the mower to tractor’s 3-point linkage. Drive from
tractor’s rpm is transmitted through intersecting axis gear (3) on PTO shaft (7), which through
intersecting axis gear (8) drives the cutterbar (4). On the cutterbar, there are discs with two knives
each. Hydraulic cylinder (2) is used to adjust the mower to working position. It is supplied from outer
hydraulics of the tractor. Main frame, on which the cutterbar is situated, is supported by the springs
(9). There are also swath discs (5) mounted on the main frame.
