ABSTRACT:
In order to cut soft concrete before it has completely hardened, or about 12 to 18 hours after finishing, a rotating cutting blade and its drive motor are mounted on a wheeled support platform. The blade extends through a slot in the platform, and also through a skid plate depending from the platform, in order to cut the concrete below the skid plate. The slot and the skid plate are sized to support the concrete as it is being cut and to inhibit cracking and chipping of the concrete during cutting. The slot preferably has as little space as possible between the sides of the slot and the adjacent sides of the cutting blade. An extendable handle allows the device to be used beyond the physical reach of the operator.
