The power required for the disc milling cutters becomes a trailer. But it depends entirely on the power source of the speed of the milling disc and the amount and tractor taken by a cardan shaft 16. The power source for the weight of the tools such as conveyor belts from each cutting edge of the milling disc comes from a milled earth, whether it flies into the trailer zinmotor on the trailer. The two discs or in front of it falls on the lawn. 55 milling cutters are driven in such a way that they rotate in the sel-The object underlying the invention is ben the sense of rotation as the wheels 7 rotate.

By actuating this output, the disk milling cutters 8 can be solved in the device of the invention in that the counter-clockwise ⁶ ° dea ground is lowered or the circumferential disk milling cutters removed from it are brought together again. The side milling cutters 8 are equipped with shovel work with knives 18 trailing in the milling slots. The shovel knives 18 promote clearing spurs over the surface of the humus soil to promote the excavated earth to the trailing clearing, where they are lukewarm spurs 19 along on both sides of the side milling cutters.

C? The clearing chains expediently run in cages, which sit on runners that press down the humus soil on both sides of the milling slots. 1. Device for creating a surface By assigning the Räumspome to the drainage on existing lawns, with 5 disc milling cutters and the subsequent georaneten of the vehicles driving across the square (Zugma- conveying means will be a very clean production of the machines with trailer) with revolving cutting guards. Because the output milling cutter Drainage slots in the humus soil milled earth into the receptacle of a second cutting and the milled earth is required in a vehicle driving on it, is a con (ang container discharge, thereby ensuring continuous work progress, as em draws that the counterclockwise stop to uncouple a filled trailer rotating disc milling cutter (8) the earth is dispensable. cooperation with in the milling slots (9) after- Another embodiment of the invention is in progress Räumspornen (19) indicated on the upper claim. area of the humus soil (6) promote where it is 15 In the drawing is schematic and partially in a preferred embodiment of a clearing cut running on both sides of the side milling cutter (8) chains (21) falls that show a transport connection to the device according to the invention and a transverse conveyor belt (25, J 2), explained in more detail below. that shows the earth in the receptacle of one since borrowed second vehicle (13) traveling along, ao Fig. 1 shows a section through a lawn sports field tet. with rear view of the device,
