Abstract: A mowing device for the treatment of vegetations is adapted for the attachment to a carrier and for the connection to a drive unit. The mowing device includes a frame, on which mowing spindles are mounted which are provided on one side with mowing blades and on the opposite side with distributing elements for the connection to transmission members. On the frame, a transmission mechanism for driving the mowing spindles is further positioned. The mowing spindles are arranged in two mutually parallel rows, defined by longitudinal lines, located in a mutual distance separation. The mowing spindles of each row are interconnected by means of the transmission members. The centers of the mowing spindles of the first row on a line are located in a mutual spacing. The centres of the mowing spindles of the second row on the line are located in the mutual spacing.

Abstract: Travelling device (20) particularly for self-propelled mower comprises a frame (1) provided with several identical travelling units (21) arranged on its circumference. Each travelling unit (21) comprises a flexibly suspended travelling wheel 92) rotating on its horizontal and vertical axes. A motor unit (3) with a driving shaft (13) is arranged on said frame (1) for driving a working device and said travelling wheels (2). Said travelling wheels (2) are arranged in said travelling units (21) turnably on vertical axis in an unlimited angular range of 360°.
