| Zusammenfassung: | 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. |
