ABSTRACT:
A control mechanism for operably controlling three functions of the loader mechanism on a tractor-loader is disclosed wherein a longitudinal, fore and aft movement of the control lever effects operation of one function, while a transverse movement of the control lever effects operation of a second function, and a rotational movement of the control lever about the axis thereof controls the third function of the loader mechanism. The control lever includes an elongated inner member affixed to a plate being supported from the frame by a universal joint permitting pivotal movement of the plate in the transverse and longitudinal directions in response to a corresponding manipulation of the control lever. The control lever also includes an elongated tubular member rotatably mounted on the inner member and connected to an additional linkage to translate rotational movement of the elongated tubular member into linear motion for controlling operation of an auxiliary device on the loader mechanism.
