Claim:
A material removing device for removing an overlaid material from a substrate material, said material removing device comprising: (a) a frame, (b) a power source, (c) a cutting reel including (i) a shaft rotatably mounted to said frame and mechanically associated with said power source for powered rotation, (ii) support members fixed to said shaft and (iii) blade members and bumper members fixed to said support members and arranged in an alternating spaced fashion, said blade members presenting cutting edges set at a cutting diameter for cutting said overlaid material, said bumper members presenting generally smooth non-cutting surfaces set at a bumper diameter which is generally equal to or greater than said cutting diameter, whereby when said cutting reel is rotated, said blade members cut and remove said overlaid material while said bumper members contact said substrate surface and thereby prevent damaging contact between said cutting edges of said blade members and said substrate surface.
