A mower (1) with a mowing aggregate is pivotally connected with a frame (7) for mounting on the lift-suspension of a tractor (8) in order, by a swinging movement, to be movable between a working position outside the track of the tractor and a transport position. In the working position a moment of force may be transferred from the tractor to the mower (1) to lift it as a whole, for instance during turns in the field. To eliminate the risk of a lateral tilting of the tractor the mower comprises at least one support wheel (9, 10) which is pivotal around an upwards directed axis (11, 12) and is suspended for raising and lowering between an inactive raised position, when the mowing aggregate is lowered for a windrowing working position, and an active supporting position, in which the support wheels (9, 10) at least partially carry the weight of the mower (1) in its raised position.
