<p>The retractable tractor mower, which is primarily designated for attaching onto a mulcher as a tractor attachment, provides apart from the known performance of automatic retracting from obstacles also the trailing of the cutting blades at a predefined distance from the earth surface regardless its configuration accompanied by minimum additional friction and also manual control of the lateral movements of the cutting blades during mowing directly from the operating seat of the driver or his assistant. On the mower according to the invention, the operating element (9) is controlled past the retractable lever (13) and parallel to element (14), which is operated by the tractor driver or his assistant directly manually from their workplace, this means the driver's seat or anywhere else, preferably via valve (15), and on the rear side on the chassis (1) there is in the transverse direction on a vertical axis (16) a freely rotating bracket (17) which reaches beyond the chassis (1) and where on its free end there is a freely rotating wheel (18), which is adjustable by height regarding the surface (19) or earth structure.</p> |
