The aluminum and stainless steel Har-Tru Gator Rake tine system lightly sweeps and grooms the surface of the court spreading the clay evenly. The rake helps prevent the buildup of clay and keeps moisture at an optimal level. These rakes are the perfect tool for indoor courts and HydroCourts. The tines are more aggressive that the steel bristle brooms.The tine system is composed of stainless steel rods and comes with adjustable tine cartridges that move in half inch increments. They can be easily adjusted as the tines wear. The rake tine cartridges can be easily replaced and are user friendly. Additional weight up to 150 pounds can be added to the top of the rake for scarifying the hard areas of the court, regenrating loose sliding material. Special weight towers (msut be purchased separately) can be added for that purpose.
