Abstract:
1. A concrete finishing trowel comprising: (A) a frame; (B) a motor that is mounted on said frame and that has a rotatable output; (C) an operator controlled guide handle that that extends rearwardly from the frame along a line that at least generally laterally bisects said frame; and; (D) a rotor that includes a plurality of blades which are rotatable about a downwardly extending rotational axis that is located on said line and that is at least approximately centered on the frame, wherein said trowel is dynamically balanced such that forces transmitted to the handle upon rotation of the blades in contact with a surface to be finished are substantially reduced when compared to a non-dynamically balanced trowel, wherein said trowel has a center of gravity that is offset longitudinally behind the rotational axis of the rotor and laterally to the right of said line when viewed from behind the trowel.
