Abstract
A broom assembly for attachment to a vehicle is adapted to rotate a brush having a tubular core. The broom assembly includes a center section, a left side plate, a right side plate, an idle hub on one of the side plates and a drive hub on the other of the side plates. These hubs define a core axis about which the brush is rotated. A first linear actuator is adapted to move the left side plate along an axis that is parallel to the core axis between a left open position and a left closed position, and a second linear actuator is adapted to move the right side plate along an axis that is parallel to the core axis between a right open position and a right closed position. The broom assembly may be operated in a work mode and a maintenance mode.
