Abstract
A haymaking machine having a frame supporting at least one raking wheel equipped with tool-carrying arms controlled during work. The raking wheel is rotatable about a support pin which carries a control cam and which is free in rotation in relation to the frame during work. The support pin is connected to at least one support which is offset in relation to the support pin in the direction of movement of the machine, with the support being stationary in relation to its connection to the support pin in the horizontal plane. The support thus assures a continuous predetermined orientation of the support pin and of control cam as a function of the direction of movement to permit formation of well-formed and regular windrows during movements of the haymaking machine both in a straight line or around curves or turns.
