Abstract: A novel beet harvesting machine is disclosed having a rectangular frame with a front yoke and longitudinal and transverse support beams and being pulled by a tractor at the yoke for harvesting and delivering beets into a truck. The beet harvesting machine of the present invention utilizes hydraulic motors for powering the flailing of the dug beets rearwardly into the machine, the conveying of the flailed beets further rearwardly in the machine, the delivering of the beets laterally and the elevating of the beets upwardly and into the truck. The reservoir for the hydraulic fluid is integral with and disposed in the center of one of the longitudinal and transverse beams. A pump is provided for delivering the fluid from the reservoir and into the hydraulic motors of the present invention. A cooler for dissipating heat in the fluid is further provided.
