Abstract
The mower comprises at least two mowing groups 6, each of the at least two mowing groups 6 being composed of a cutting bar 8 equipped with cutting elements, the cutting bars 8 being connected to one another by a joint 9 and the mowing groups 6 being connected to the chassis 1 by a suspension device 12, 20, 18; 12, 20, 39. The suspension device 12, 20, 18; 12, 20, 39 comprises an intermediate structure 12 movably connected to the chassis 1 by a connecting device 18; 20, 39. Each one of the at least two mowing groups 6 is connected to the intermediate structure 12 by a joint 16 having an axis at least approximately perpendicular to the vertical plane containing the longitudinal axis of the corresponding cutting bar 8. The joints 16 are capable of movement in the direction crosswise to the direction of work 25 in relation to the intermediate structure 12.
