  • Patent number: 4974400
    Abstract: A control linkage for use on a tractor to control hydraulic implements associated therewith is disclosed wherein a control lever controlling the raising and lowering of the header forming a part of an implement mounted on a tractor is provided with a control device detachably connected thereto and engageable with a second control lever operably controlling the speed of a hydraulic motor powering the components of the implement attached to the tractor. The control device automatically moves the control lever for the speed of the hydraulic motor to a slow position whenever the header lift control lever is moved to effect a raising of the header relative to the ground. The speed control lever is spring-loaded toward the fast position so that a return of the header lift control lever to lower the header into an operating position will result in an automatic return of the speed control lever to a fast position.
