Abstract

See full text

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 the transmission members. The centers of the mowing spindles of the first row on a line are located in a mutual spacing. The centers of the mowing spindles of the second row on the line are located in the mutual spacing. The centers of the mowing spindles of the second row are offset in the direction of the lines by a one-half P/2 of the spacing P with respect to the centers of the mowing spindles of the first row on the line. A connecting line of the center of each mowing spindle of the first row on the line with the center of the immediately adjacent mowing spindle of the second row on the line forms with parallel longitudinal lines an acute angle, for which the following applies: L tg a=P/2 The size of the angle a is in the range from 15° to, 60°. The transmission mechanism for driving the mowing spindles with two transmission devices mounted side by side on the frame and mutually connected. The first transmission device is arranged for the rotation in one rotational direction and is connected via transmission members with the mowing spindles of the first row on the line. The second transmission device is arranged as a reverse device for an optional rotation of the output shaft of the gearbox in both rotational directions, and it is associated via transmission members with the mowing spindles of the second row on the line.
