Latest Patents

One of Harwood's latest patents is the "Switch Actuating Assembly." This invention provides a support means for maintaining the switch in a fixed position relative to the orientations of a movable member. The design includes a motion response element that is operably connected to the movable member, allowing it to move in two directions based on the member's orientation. An actuating member engages the switch to transition it from a first to a second position, utilizing frictional contact with the motion response element.

Another significant patent is the "Combined Depth-Control and Wing-Lift Hydraulic Circuit." This hydraulic circuit is designed for use with farm implements that have a tool bar. It allows for the raising and lowering of the tool bar to control depth effectively. The circuit also includes pivotally connected wings that can be adjusted between horizontal and vertical positions, enhancing the functionality of the implement. This innovative design features a 'wheel-tuck' mechanism that draws wing wheels inward when in a vertical position, optimizing performance.
