ABSTRACT:
A brushing machine for grapevines is disclosed made up of rotating brushes supported on a frame that is supported on a tractor. Each brushing mechanism has several brushes with radially extending bristles rotatably supported on a vertically and horizontally adjustable frame. The brushes are individually driven and pass along both sides of a grape trellis. The frame supporting the axles of the brushes may be swung to adjust the angle of the brushes to the ground for any particular tractor speed, so that as the tractor moves forward and the brushes rotate, the resultant motion relative to the trellis of the tips of the brush straws is in a vertical direction.
