This abstract is based on an alternate, improvement control method, to assist the drivers who have had, or recently discovered they have hand or finger disabilities and can no longer use our easy grab ball control disc, because it is too difficult for them to pull against some of the low-end spreader models that use very heavy springs to keep the tow-behind spreader center-column-handle-lever in place, each time the slide gate porthole chute is repositioned. This alternate control method consists of two (2) improved, modified control discs, that incorporates (fulcrum pivot mechanics) to be used in the event the operator's hand has arthritis, carpel tunnel, difficulty in closing fingers, fist, or other hand deficiencies, which makes them unable to pull and use our original twine line grab ball control disc, against the heavy force of those springs installed by the manufacturer. These two (2) improved fulcrum-pivot-design controls will make it very easy for the driver to still open and close the slide gate porthole chute from the driver's seat, because they use (fulcrum physics) less force to move a heavier load.
A claim is made for the embodiment improvements of the fulcrum pulley control kit, which is comprised of a round disc with a center groove 6 inch pulley, to wrap, coil, or pull a preferred nylon twine around that can be shortened and lengthen, by rotating the said pulley to a 90 degrees clockwise and counterclockwise rotational movement that the driver uses to change the length of the said twine-line to make it change the position of the slide gate discharge porthole chute, is mounted on the end of the support shaft at the drivers' seat, whereas,
A claim is made for the embodiment improvements of the fulcrum pivot handle and arm control kit, which is comprised of a long handle with a 90 degree (L) shorter arm attached to the straight handle lever, mounted onto the end of the support shaft, located at the drivers' seat, that where attached, will cause the other end of the handle to pivot, with enough “throw” (travel) to move the said twine-line six (6) inches, when pushed or pulled by the driver, with a back and forth movement, applied by the operators hand, will cause the shortening and extending of the said twine, in such a manner, so as to change position of the spreaders handle lever , and overcome the extra pressure applied by the manufacturer's springs, to open and close the slide gate porthole chute, by using fulcrum pivot mechanics, which uses less force to move a heavier load.
