ABSTRACT:
A machine for scraping a floor covering from a floor has rear drive wheels and a forward blade assembly. Arms which each rotate independently on the frame at one end are connected to the blade assembly which independently rotate on their other ends. Thus, the blade is able to float and follow the contour of the floor even if the wheels and blade are riding on an uneven surface. The pitch and elevation of the blade assembly can be changed individually or simultaneously without inhibiting the floating motion of the blade assembly.
