Abstract
A sweeper including a rotating brush or drum supported by a float arm movably coupled to a bucket. The float arm is coupled to a linkage to movably support the float arm between a retracted position and a forward position. Float arm is supported independently of a hood connected to the bucket and is movable through linkage relative to hood. In an illustrated embodiment, float arm is rotationally coupled to linkage to compensate for height variations and/or provide a mechanism to rotate linkage to move the float arm forward relative to the bucket.
