A tennis court preparation device for scraping tennis court surfaces, which can be pulled across a tennis court in a direction of travel by a traction vehicle, including at least one frame and at least one support device for supporting the frame on the tennis court surface that is to be prepared. At least one coupling system for coupling to a traction vehicle, and at least two main scraper elements connected to the frame, which are linked to each other in such a way that the gap between the two main scraper elements tapers in the direction opposite to the direction of travel, leaving a space between the two main scraper elements at the rear ends of the main scraper elements as seen looking in the direction of travel, so that the scraped-off tennis court surface material is left in a trail formed by the space.
