<p>An agricultural machine, e.g. a mower-crusher, comprises a frame for connecting same to the lifting hitch of a tractor. The frame is provided with at least one weight relief spring (22) and is dimensioned such that, during operation, the weight relief of the agricultural machine is substantially independent of the position of the frame relative to the lifting hitch, which position is variable within a certain range. Specifically, the weight relief varies maximally 10% in value within a range of maximally 30 DEG , the said range being located in an interval relative to a horizontal plane of from approximately -15 DEG to +30 DEG .</p> |
