Brushing device and method

Brushing apparatus comprising:

• a motor vehicle;
• a tool-holder means carried by the motor vehicle;
• means for raising and lowering the tool-holder means relative to the motor vehicle;
• an assembly removably mounted on the tool-holder means and including container means pivotally mounted relative to the tool-holder means about a first horizontal axis and having an opening into which material to be brushed is deposited during a brushing operation and through which material within the container means is discharged when emptying the container means, brush means rotatable about a second horizontal axis, support means mounting the brush means on said container means for free swinging movement relative to the container about a third axis, and drive means for rotating the brush means;
• container operator means controlled from and carried by the motor vehicle for pivoting the container means about the first horizontal axis between a brushing position and a container-emptying position;
• said brush means having a center of gravity relative to the third axis such that the brush means lies adjacent to the container opening in the brushing position of the container means, and is spaced from the container opening to expose the opening in the container-emptying position.
