Abstract
A debris sweeper has a powered rotary brush for sweeping debris, such as aerator cores, from a turf surface into a debris collecting hopper. The brush and hopper are carried on a wheeled tow frame. The hopper is pivotally supported on a pivotal lift frame that moves the hopper between a lower, debris collecting position and an upper, debris dumping position. The lift frame pivots on the tow frame behind an axis of a pair of wheels while the hopper pivots on the lift frame in front of the wheel axis. This ensures that positive weight is kept on the tongue of the tow frame at all times.
