Abstract
A hay-gathering machine for pulling windrows of hay, turning the hay over, and scattering it, having a rake-wheel comprising a plurality of tine-carriers radially directed outwards from an almost vertically-pointed swivel pin, wherein the tine-carriers at their outer ends are provided with rake-tines. At the end of each tine-carrier, which is directed toward the swivel pin of the rake-wheel, there is attached at least one control lever, which, for the pulling of windrows, is connected with a first open control channel in a tensional or a form-locking, or in a purely form-locking manner. The tensional or form-locking connection of the control lever with the first open control channel is made by means of a spring or the like, while the purely form-locking engagement of the control lever into the first control channel is made by means of cooperation of the roller on the control lever with a guide way which is parallel to the first control channel. By means of a second control channel, which is displaceable in longitudinal direction to or around the swivel pin of the rake-wheel, the tines on the tine-carriers are changed into a fixed position almost vertical to the ground.
