ABSTRACT:
More specifically, the invention includes a single lever control mechanism for controlling the operation of hydraulic cylinders and including a control housing, a manually operable lever, and a support member housed in the control housing and having a supporting surface. The single lever control mechanism also includes a pivot member rigidly connected to the lower end of the lever and supported on the supporting surface of the support member for rocking movement from a neutral position in a first pivotal direction and in a second pivotal direction transverse to the first direction. The control mechanism also includes a first cable attached to one side of the pivot member and being adapted to be operably connected to a first hydraulic cylinder for actuating that hydraulic cylinder in response to pivotal movement of the lever and the pivot member in the first direction. The control member also includes a second cable attached to another side of the pivot member, transverse to the one side of the pivot member, and being adapted to be operably connected to a second hydraulic cylinder for actuating that hydraulic cylinder in response to pivotal movement of the lever and the pivot member in the second direction.
