Grass or green area aerating device, has roller with two discs connected by six tie rods for tightening discs in sandwich between two nuts, and six pegs mounted each one on common shaft to produce curvilinear shaped aeration cavities
The device has a roller with two discs (1) connected by six tie rods (5) having threaded ends for tightening the discs in sandwich between two nuts. Six pegs (3) are mounted each on a common pivoting shaft (4) to produce curvilinear shaped aeration cavities. The rotation of the roller generates the penetration of the pegs, slightly oblique, with progressive depression until its maximum. Vertical axis of the pegs is in superposition with a vertical axis Y of a point (9).
