PROBLEM TO BE SOLVED: To naturally recover scraped off materials such as roots of turf and earth and sand, etc., taken out of a hole by a turf perforator while perforating the turf without scattering thereof on a perforated turf surface when perforating the turf with the turf perforator. SOLUTION: This turf perforator is capable of filling scraped off materials of each hole part in the interior of each spike 2 of the turf perforator when inserting the spike 2 into the turf in order to bore each hole in the turf. The scraped off materials are successively inserted from the lower part of the spike 2 thereinto and the already inserted scraped off materials in the interior are pushed out of the opened upper part. Each housing box 5 serving as a pan is mounted on the vicinity of the upper part of the spike 2 to house the pushed out and scraped off materials in the housing box 5.
