摘要: A mower, preferably having a plurality of mower drums rotatable about respective vertical axes and spaced transversely apart upon a support beam, is connected to the elevatable three-point hitch structure of a tractor by a linkage allowing vertical displacement of the mower in one angular position of the beam with respect to the hinge assembly so that the mower drums may follow the contours of the ground. The junction between the frame and the hinge assembly is provided with abutment or stop selectively positionable to retain the attachment device, in an elevated position without supporting the frame on the ground to facilitate reattachment of the mower to the tractor.
