Abstract
A machine for removing the top foliage of sugar beets having a frame with longitudinal side walls and a longitudinal center beam carrying three gear boxes. Rotor assemblies drivably connected to opposite sides of the gear boxes are rotatably mounted on the side walls. A PTO drive is connected to a main drive shaft located above the center beam. A chain and sprocket speed reducer surrounds the main beam and transmits power from the main drive shaft to drive shafts connected to the first and second gear boxes. The chain and sprocket speed reducer is located within a housing mounted on the main beam. The main beam extends through the housing. Each rotor has a cylindrical member carrying a splined sleeve that is mounted on a splined hub connected to an output shaft of a gear box. A bearing assembly mounts the outer end of each cylindrical member to a side wall. A plurality of flail carrying assemblies having flexible rubber flails are mounted on each cylindrical member. The first and second rotor assemblies are driven in the forward direction of movement of the machine. The third or last rotor assembly is driven in an opposite direction and functions to clear the foliage from the rows of beets and remove the foliage from the back side of the beets. Ground engaging wheels are mounted on a transverse beam. Links pivotally mount the transverse beam to the side walls. Crank arms connected to a transverse shaft are controlled with a hydraulic motor to change the elevation of the machine relative to the ground engaging wheels thereby adjusting the working height of the flails.
