Some crops, such as soybeans, grow close to the ground, having a low canopy relative to that of weeds growing interspersed in the crop. A farm implement removes weed growth above the crop canopy. The implement has a chassis with at least three wheels connected to the chassis, a cutting mechanism, mounted at a front end of the chassis, a means for collecting weed growth cut by the cutting mechanism, mounted on the chassis, means for generating and selectively applying rotational torque to at least one of the at least three wheels and means for a user to guide the chassis down the rows in which the crop is grown.
