Abstract
A power sweeper has a handle having a first end graspable by a user and a second end, a drive shaft extending along the handle, and a power head coupled to the handle to rotate the drive shaft. A gear box is coupled to the drive shaft adjacent the second end, and a brush is coupled to the gear box for rotation in response to rotation of the drive shaft. The power sweeper includes an axle, and first and second wheels coupled to the axle. A shield is coupled to the gear box and defines an aperture through which the handle extends. The axle is moveable with respect to the shield and the brush to adjust an angle between the handle and the ground surface.
