Abstract: An oversleeve for preventing crop material from wrapping around an agricultural implement shaft. The oversleeve is disposed over the implement shaft and affixed to a stripper pan so it does not rotate with the shaft. The oversleeve is preferably made of a polymer composite material. Removal of dirt between the shaft and oversleeve is effected by a helical groove arranged so the dirt is driven to the ends of the oversleeve.

Abstract: Two mower-conditioner lugged rollers provided with a four-gear timing system that allows the rollers to separate while still maintaining the timing.

Abstract: An apparatus to maintain optimum engine speed and cutter wheel speed to maintain peak power output of the engine and peak flywheel effect of the stump cutter wheel and method for maintaining optimum engine speed. The stump cutter has a rotating cutting wheel powered by an engine, and the cutter is mounted to be moved laterally. The mounting includes a boom and at least a first hydraulic cylinder for urging the boom to move along the path of travel over the surface of a stump. The hydraulic cylinder is activated by a hydraulic circuit which includes a source of pressurized hydraulic fluid. A pressure hydraulic line connects the source of hydraulic fluid to a first port of the hydraulic cylinder and a return line is connected to a second port of the hydraulic cylinder. A valve diverts a portion of flow from the pressure line to the return line or to a sump. The valve is shiftable between at least a first and a second position.

Abstract: A stump cutter having a frame including a movable boom and an engine mounted on the frame. The drive engine includes a rotating output shaft and cutter drivably attached to a rotatable cutter shaft disposed on the boom. A drive transmitting shaft is provided for connecting the output shaft and the cutter wheel shaft. A coupler is provided for connecting the first end of the shaft to the engine output shaft and a second coupler is provided for connecting the second end of the shaft to the cutter shaft.
