Latest Patents
One of Yarbrough's latest patents is the "Feed reverser for a combine header." This invention provides a supplementary header drive that allows the header components to operate in reverse. This feature is particularly useful for clearing blockages of crop material in the platform auger or feederhouse conveyor. The drive is powered by a hydraulic motor and is selectively connected to the header drive system through a hydraulically actuated clutch. The design ensures that the clutch engages before the hydraulic motor begins to rotate, enhancing operational efficiency.
Another significant patent is the "Chaff spreading arrangement for a combine." This invention funnels chaff discharged from the cleaning shoe towards a pneumatic conveyor, which transfers it to a rear-mounted straw chopper. By mixing the lighter chaff material with heavier straw, this arrangement helps to spread the chaff more widely and uniformly. The upward intake at the conveyor inlet aerodynamically screens out heavier materials, allowing them to fall to the ground.
