This is the first machine available for maintaining clay tennis courts, it scarifies the surface layer for fast weekly maintenance.
It can dig deeply to the base layer of a clay court to a depth of 30mm, thanks to its array of 104 tilting blades, without disturbing the white lines. The speed of the motor regulates how finely the clay is ground up.
The blades are easily changed and are hardened due to a special treatment of the steel.
The regulator wheel adjusts the depth and therefore the force of impact of the tilting-rotating blades, which cut into the clay surface layer to a greater or lesser depth. The accelerator lever controls the rotation of the four-shaft rotor: the faster it runs, the more it reduces the clay to powder, while if operated at a lower speed, the clay is broken up into tiny clods.
The machine is fitted with a quick-fitting lead-weighted cover to shield the operator from the dirt of the scarified clay, and to spread the built-up excess clay when performing deeper digging operations. Also, a safety handle prevents errors or problems in the event of an emergency: if the operator removes his hand from the handle grip the engine cuts out, the rotor is blocked and the machine stops moving forward.
Finally, the process can be followed up by the Rinoroll machine to consolidate the courts and make them playable immediately after maintenance.
It is powered by a Honda 5.5hp petrol engine.
