Abstract: A locking system for attaching a threshing and/or separating element to a mounting lug on a rotor of a threshing system of an agricultural combine, including a single bolt attachment with multiple points of contact between the element and the lug created by a convex portion extending from an inner surface of the threshing and/or separating element cooperatively engaged in a recessed portion of the mounting lug. The locking system resists loading conditions generated when the crop mat engages the element, prevents radially outward movement of the threshing and/or separating element relative to the mounting lug, and reduces the stress on the mounting hardware during harvesting operations.

Abstract: A cart for draining, filtering and recycling oil or similar viscous fluids from vehicles comprising a wheel mounted fluid receiving chamber having a front to rear slope, handle means for positioning the open chamber beneath a vehicle, vertically disposed baffle plates positioned within the chamber to reduce movement of the fluid collected therein, drain means connected to the rear of the fluid receiving chamber and in fluid communication with a pump and filter means mounted alongside the chamber which provides pumping and filtering of the collected fluid to remove particles entrained therein and reintroduction of the filtered fluid back into the vehicle.
