A transportable farm machine for windrowing products includes a frame which can be connected to a tractor, a rotor mounted to the frame for rotation about a vertical axis, and a plurality of toolholder arms mounted to the rotor such that the tools mounted on the toolholder arms may form the product into windrows during rotation of the rotor. Each of the toolholder arms includes an inside part mounted to the rotor and an outside part to which the tools are mounted and which is conencted to the inside part by a joint about which the outside part can be displaced between a work position and a transport position. The joint includes a first pivot for pivoting the outside part around the longitudinal axis of the inside part, a second pivot for pivoting the outside part about an axis forming a positive angle relative to the axis of the first pivot and a locking device for locking the outside part in the work position. For transport, the outside part is pivoted about the axis of the second pivot to the transport position in which the outside end of the outside part is connected to the joint of an adjacent arm. As a result, the outer periphery of the machine corresponds to a circle lying on the outside ends of the inner parts, and the size of the farm machine is reduced.
