Abstract
An apparatus for removing at least one surface layer from a floor or the like comprises a machine body having a longitudinal axis, rear weight-bearing guide wheels, and a front weight-bearing wheel. A front weight-bearing scraping apparatus is pivotable with respect to the machine body by a cylinder located between the machine body and the front weight-bearing scraping apparatus. The machine body is thus configurable between a first machine transport position in which the front weight-bearing wheel contacts the surface being scraped and the front weight-bearing scraping apparatus is elevated from the surface being scraped and the longitudinal axis of the machine body is substantially parallel with the horizontal plane of the surface being scraped; and a second surface-scraping position in which the front weight-bearing wheel is elevated from the surface being scraped and the front weight-bearing scraping apparatus contacts the surface being scraped and the longitudinal axis of the machine body is aparallel to the horizontal plane of the surface being scraped.
