Abstract:
A wheel rake having a main frame to which a wheel rake arm is pivoted, an actuating rod is moveable on said main frame for raising and lowering said wheel rake arm through a spring assembly, said spring assembly comprising,a rod connected at one end to said rake arm and having a stop at its opposite end,a sleeve on said rod,a coil spring on said rod between said sleeve and said stop,linkage connecting said sleeve to said actuating rod whereby movement of said actuating rod for lifting said rake wheel places said coil spring in compression, andsaid linkage being pivotally connected between said sleeve and said actuating rod such that said linkage will transmit a tension force, but not a compressive force whereby unintended lifting of said lift arm will not transmit a compressive force to said actuating rod.
