Abstract
A machine for pulling weeds from rows having crops, as sugar beets. The machine has a transverse tool bar carrying a hitch. The hitch connects the tool bar to a tractor. A plurality of weed-pulling units are mounted on the tool bar. Each weed pulling unit has a pair of engaging pneumatic tires that are driven in opposite directions with a hydraulic motor. A pair of gauge and guide wheels connected to the tool bar locate the tool bar and weed pulling wheels above the surface of the ground so that the engaging rotating pneumatic tires will pull weeds from the rows of crops.
