<p>A crop mowing apparatus wherein one or more mowing units (l0, ll) are mounted in a generally side-by-side relation on an elongate frame or support (l2) which extends in a direction which is transverse to the intended direction of traverse of the apparatus over a crop which is to be cut and wherein one or more further mowing units (2l) are mounted on a further elongate frame or support (l7) which is adapted at one end (l9) to be connected to a tractor and which is pivotally connected at its other end (l8) to one end of said first mentioned elongate frame or support (l2), the or each further mowing unit being slidable along said further elongate frame or support (l7) and being connected by means of a link (23) to the first elongate frame or support (l2) whereby pivotal movement of said two frames or supports (l2, l7) relative to each other will result in said further mowing unit or units (2l) sliding along the further frame or support (l7) to effect a variation in the relative configuration of the mowing units and corresponding adjustment in the overall width of the apparatus.</p> |
