A tennis court preparation device for collection of scraped-off tennis court surface material, said tennis court preparation device being towable in the direction of travel across a to-be-prepared tennis court by means of a traction vehicle, comprising:

• at least one collection bin which is delimited, laterally and in the rear area when viewed in the direction of travel, by at least one side wall, said at least one side wall being slideable by an edge on the scraped-off tennis court, the collection bin being open in the front area when viewed in the direction of travel, so that scraped-off material arranged in front of the collection bin when viewed in the direction of travel can be collected in the collection bin,
• at least one coupling element for coupling to a traction vehicle, and
• at least one bar element connected to the collection bin, said rod element, when viewed in the direction of travel, extending forward beyond the collection bin to at least the coupling device, wherein, with the aid of the bar element, the collection bin is tiltable so that said edge of said at least one side wall in the rear area does not contact the to-be-prepared tennis court anymore.

A coupling device for coupling a tennis court preparation device to a traction vehicle which can be driven across a tennis court to be prepared, comprising:

• a frame element adapted to be fastened to a traction vehicle,
