Abstract
A damping spring assembly particularly but not exclusively useful for damping the motion of rake wheels in agricultural wheel rakes. The damping spring includes a pair of extended U-bolts and a coil compression spring. The extended U-bolts are connected to spring holder bushings which bear on the ends of the coil compression spring. As the coil compression spring is compressed, a constrained resilient damping rod located within the extended shafts of the extended U-bolts is likewise compressed in length and expands in diameter to bear against the extended shafts of the extended U-bolts, thus providing a damping action to prevent snapping back of the damping spring.
