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 (6), which through
intersecting axis gear (7) 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 (8).
