  • Publication number: 20090107100
    Abstract: A swing cylinder such as those used to offset an agricultural implement may experience larges forces as it reaches the ends of its travel. A cushioning system to mitigate these forces comprises a piston with wear rings engaged thereto. The wear rings block off a usual passageway for the hydraulic fluid to flow, and provide their own, much smaller passageway. The flow of hydraulic fluid is thereby restricted in the neighborhood of the extremes of piston travel. An additional aspect of the invention is that the wear rings are pushed out of their position blocking the passageway when hydraulic fluid pressure is applied to move the piston away from the extreme position, thereby completely removing the restriction to flow in that direction.

The sweeper comprises a housing having a transversely extending sweeping brush rotatably mounted in a generally horizontal surface engaging configuration adjacent a bin structure for collection of the sweepings. The brush is directly driven by the surface engaging wheels through a frictional engagement between one or both of the wheels and expandable drive capstans coaxially affixed to the brush. A tow frame is pivotally mounted to the housing at the forward end, which frame is adapted for releasable coupling to the towing vehicle. Means are provided for controlling the pivotal angularity between the tow frame and the housing which provides selectivity in adjusting the degree of interengagement or nonengagement between the brush and the swept surface.
