Abstract: Carriage (10) attachable to a prime mover (41) for travel over turf or grass wherein the carriage (10) has idler rollers (12, 13 and 14) and a ground aeration mechanism in the form of a support axle (15) having a plurality of slicer blades (16) attached thereto. There is also provided a housing (11) having a hollow interior (33) which houses rollers (12, 13 and 14) and ground aeration mechanism (15 and 16). In use, when carriage (10) travels over turf or grass, both rollers (12, 13 and 14) and the ground aeration mechanism (15 and 16) operate simultaneously to not only roll the grass but also slice it for the purpose of facilitating moisture penetration.
