Soil aerator

A soil aerator implement for conditioning the surface of the ground while being moved there-over, comprising:

• a rigid frame assembly comprising a downwardly facing concave housing having a pair of oppositely disposed end walls for mounting a front aerator roller and a rear aerator roller jounalled thereon for rolling engagement with the ground surface;
• said rear aerator roller being located behind said front aerator roller in tandem relation relative to the direction of travel of the implement during use thereof;
• said front aerator roller and said rear aerator roller having a plurality of formations that penetrate the ground surface;
• said formations being disposed in selected spaced apart relation circumferentially around and longitudinally along said front aerator roller and said rear aerator roller;
• drive means interconnecting said front aerator roller and said rear aerator roller inter-relating rotation of the same in a predetermined ratio;
• a compaction aerator roller extending from a pair of spaced apart pivot arms pivotally connecting to said rigid frame trailing said aerator roller;
• rear aerator roller depth control hydraulic means for raising and lowering said compaction roller for controlling the depth of said rear aerator roller;
• and
• wherein said rear aerator roller depth control means includes hydraulic means supported by a transverse longitudinal frame member extending between said end walls supporting said hydraulic means pivotally mounted thereon connecting to a coupling extending from a transverse arm support member disposed between said arms supporting said compaction aerator roller.
