Abstract
A pair of centrifugally movable shoes are pivotally mounted to a mower blade support. Drive bands are supported by the respective shoes and are positioned so as to be engageable with a source of rotational movement whereby such movement is translated to the blade by the bands, the shoes and the blade support. A brake band selectively engages the shoes to decelerate them thereby braking the blade. Additionally, engagement of the brake band with the shoes moves the latter in opposition to the centrifugal force applied to the shoes during rotation. This results in the drive bands being moved out of engagement with the rotational source.
