A material handling implement includes side and wall panels composed of an impact resistant structure having low frictional resistance to the sliding movement of material therefrom. The panels are resistant to the organic acids and salts commonly found in manure and incur minimal moisture buildup on their surfaces. The preferred embodiment of the panel includes a plywood sheet encased within and bonded to fiberglass reinforced polyester sheets.

Manure spreader box

A manure spreader having an upwardly opening box-like structure with a beater mechanism at its open rear end through which material may be reduced and thrown from that end. The conveying mechanism provided in the box-like structure for moving materials to the rear beater mechanism is composed of a fore-and-aft shiftable floor extension that is supported on a fixed floor of the box-like structure. The floor extension carries a transverse vertical push-off wall supported to shift fore-and-aft on the extension. In a fully extended position, the floor extension is at the front end of the spreader box and the push-off wall is on the front end of the extension. Manure or material in the box is pushed into the beater mechanism through hydraulic power which first shifts the floor extension rearwardly and in overlying rear position with respect to the fixed floor so that the rear edge of the floor extension is closely adjacent the beater mechanism. After the floor extension moves to its rear position, the hydraulic power then operates to move the push-off to a rear position so as to move the remaining material into the beater mechanism.

Manure spreader

A material unloader having a conveyor and a distributing unit includes a control assembly operative from the tractor or towing vehicle by a single hydraulic control. A jaw clutch is provided for engaging and disengaging the distributing unit drive and the power shaft. A variable speed pulley assembly is operable to engage and disengage the conveyor drive and power shaft and to vary the speed of the conveyor over a wide range of values. The jaw clutch and variable speed pulley assembly are simultaneously controlled by a cam operated shifter assembly. The cam is mounted on a control shaft along with a pawl and ratchet mechanism indexed by a hydraulic cylinder to sequentially establish various combinations of conveyor and distributing unit drive conditions, including a condition wherein the distributing unit is disengaged and the conveyor is operating at a relatively high speed for fast cleanout of the unloader.
