Abstract
An apparatus for the removal of flooring is described. The apparatus is powered by an internal combustion engine which moves a series of crawlers. A blade is attached to a blade-holder which is situated on the front of the flooring remover. The blade is moved up and down by oil cylinders powered by an oil pump, thereby changing the angle of the blade to the floor. In addition, the blade is moved forward and backward rapidly by means of a driving shaft. The operator controls the apparatus from a seat mounted on the main body of the apparatus.
