Abstract
A rotary brush assembly that is mounted to a traction vehicle, such as a skid steer type vehicle. The brush assembly is allowed to move relative to the traction vehicle within three degrees of freedom including yaw, roll, and up and down linear motion. The degrees of freedom reduce brush wear and facilitate more effective cleaning over uneven surfaces. Up and down linear motion is accommodated by a linear sliding joint. The sliding joint is further equipped with markings that indicate to the operator where, in the range of up and down motion, the brush is located. The brush assembly is also equipped with a mounting mechanism that translates motion of a skid steered vehicle implement arm joint into yaw motion of the brush. This eliminates the need for additional hydraulic cylinders or controls to actuate yaw motion.
