Claims12
A system for treating a ground surface, comprising:
- a frame for transporting over a ground surface;
- an aeration apparatus coupled to the frame, the aeration apparatus comprising a plurality of aeration tines that form aeration pockets in the ground surface when driven to penetrate the ground surface;
- and
- a flexible roller system coupled to the frame and including a first roller having a first generally rigid cylindrical surface, a second roller having a second generally cylindrical surface, a flexible axle member extending through the first and second rollers such that the first roller is positioned proximate the second roller,
- a first constant force spring having a first end connected to the frame and a second end connected to the flexible axle member proximate a first free end of the flexible axle member, a second constant force spring having a third end connected to the frame and a fourth end connected to the flexible axle member proximate a second free end of the flexible axle member, and an intermediate constant force spring having a fifth end connected to the frame and a sixth end connected to the flexible axle member at a position intermediate the first and second rollers.

A system for treating a ground surface, comprising:
- a frame for transporting over a ground surface;
- a soil treatment apparatus coupled to the frame such that the soil treatment apparatus penetrates the ground surface when the frame is transported over the ground surface;
- and
- a flexible roller system coupled to the frame and including:
- a first roller having a first generally cylindrical surface extending between first and second roller ends;
- a second roller having a second generally cylindrical surface extending between third and fourth roller ends;
- a flexible axle member extending through the first and second rollers such that the second roller end is positioned proximate the third roller end;
- a first constant force spring having a first end connected to the frame and a second end connected to the flexible axle member proximate the first roller end;
- and a second constant force spring having a third end connected to the frame and fourth end connected to the flexible axle member proximate both of the second and third roller ends.
