Abstract
The invention relates to a rotary mower driven from below. According to the invention, the upper part of a beam (4) comprises, in the vicinity of cutting elements (5, 7) which rotate in a high plane of rotation, a bulge (30, 32) the upper face of which is at least approximately planar and extends at least approximately parallel to the plane of rotation. The bulges (30, 32) cover at least approximately the space of the upper face of the beam (4) located under the cutting tool support (51, 71) of the high cutting elements (5, 7), and in part at least approximately the space of the upper face of the beam (4) not swept by the cutting tools (9) of the neighboring low cutting elements (6, 8).
Claims16
A rotary mower adapted to be moved in a work direction during use, said rotary mower comprising:
- (a) a beam having an upper face;
- (b) at least one first cutting element extending above said beam, said at least one first cutting element being connected to an upwardly directed shaft having a longitudinal axis, said upwardly directed shaft being guided in rotation on said beam, said at least one first cutting element being made up of a cutting tool support provided with cutting tools rotating in a first plane of rotation;
- (c) at least one second cutting element extending above said beam and located adjacent to said at least one first cutting element, said at least one second cutting element being connected to an upwardly directed shaft having a longitudinal axis, said upwardly directed shaft being guided in rotation on said beam, said at least one second cutting element being made up of a cutting tool support provided with cutting tools rotating in a second plane of rotation, said second plane of rotation being lower than said first plane of rotation during use of said rotary mower, the volume swept by said cutting tools associated with said at least one second cutting element partially overlapping the volume swept by said cutting tools associated with said at least one first cutting element;
- (d) drive means for driving a first one of said cutting elements in rotation;
- and
- (e) transmitting means for transmitting the drive from said first one of said cutting elements to the second one of said cutting elements to drive said second one of said cutting elements in rotation, said transmitting means being able to be desynchronized;
- (f) said upper face of said beam comprising in the vicinity of said at least one first cutting element a bulge having an upper face, said upper face of said bulge being at least approximately planar and extending at least approximately parallel to said first plane of rotation of said at least one first cutting element, said bulge covering:
- (i) at least approximately the space of said upper face of said beam located under said cutting tool support associated with said at least one first cutting element and
- (ii) in part at least the space of said upper face of said beam not swept by said cutting tools of said at least one second cutting element.
