<p>The mechanism is for working e.g. on a gravel tennis court (4). It comprises a vehicle with wheels (2, 3) to move over the court surface and carrying a number of tools including a set of brushes (16), a roller (11) on a transverse axle (10), and one or more rotatable cutting or raking tools (15) operated by drive means (5). The drive unit may also drive the wheels (2, 3). The tools may be adjustable (12, 17, 18, 10) relative to the surface (4). The drive unit may contain a hydraulic pump to operate the adjusting means and tools. The drive unit may be reversible. The tools may be arranged as two sets, symmetric relative to the roller.</p> |
