A concrete trowel includes a frame, a drive assembly including an electric motor mounted on the frame having an output shaft extending from the motor defining a drive axis, a guide handle extending from the frame for controlling the trowel, a battery pack for supplying electrical power to the motor, and a rotor including a plurality of blades, the rotor rotatably coupled to the drive assembly for rotating about a rotational axis that is coaxial with the drive axis.

Concrete trowel

A concrete trowel includes a frame, a drive assembly including a motor mounted on the frame and a drive hub configured to receive torque from the motor, a rotor rotatable about a rotational axis and including a plurality of blades, wherein the rotor includes an attachment portion that is received within a receiving portion of the drive hub, and a quick-change coupling for selectively attaching the rotor and the drive hub for co-rotation therewith. The quick-change coupling includes a spring that imparts a spring force on the attachment portion of the rotor and wherein the spring remains on the drive hub when the attachment portion of the rotor is removed from the quick-change coupling.
