ABSTRACT:
A motor powered rotary trowel employs a plurality of radially arranged trowel blades which can be adjustably tilted on their support arms in either direction and are mounted on a drive shaft which can be driven in either direction thereby enabling the weight of the trowel to be selectively supported on the edges on one side or the other of the trowel blades. In an alternative embodiment, selected parts of the trowel are arranged to fold to facilitate transport.
