A swather having a horizontal bar with a device for connection to a towing vehicle and a generally horizontal bar, transverse to the first one, each end of which is associated with a generally vertical member bearing a wheel. The assembly of the transverse bar and the vertical members being associated with generally horizontal long arms directed toward a first end of the first horizontal bar and pivotally connected to the transverse bar or the vertical members, so that the arms, when extended to a working position, provide a V-shaped or Y-shaped configuration. Each arm is equipped with a pivoting wheel with tyre at its end remote from the transverse bar, or distal end, and with wheel rakes. At least the pivoting wheels with tyres are equipped with shock absorbing means capable of attenuating impulsive loads due to impact of the wheels against ground irregularities.
