Abstract
A hydraulically actuated endgate is presented which places a panel directly in front of the beaters of a manure spreader. The endgate retains all of the manure within the spreader box until the spreading site is reached. The panel is hinged mounted along its top edge to a generally U-shaped structural member. The central portion of the U-shaped member spans the box just in front of the beater. The legs of the U-shaped member are of equal length and extend forward along the sides of the spreader. The very ends are pivotally attached to the box, one on the left, the other on the right. A hydraulic piston attached to an arm secured to one of the pivot points makes it possible to move the structural member upward through an arc of about 100 degrees, then back down to the rest position.
