Soil pitting and damming implement and process

A tractor drawn soil pitting and damming implement, comprising:

• a frame adapted for attachment behind a tractor in transverse orientation thereto:
• a series of cultivator shanks transversely spaced along the frame;
• a shaft mounted to the frame behind the cultivator shanks for free rotation about a transverse axis in relation to the tractor;
• spider wheels affixed to the shaft for rotation therewith behind and substantially aligned with the cultivator shanks, having arms extending substantially radially outward to ends;
• individual blades mounted to each of the spider wheel arm ends for successive engagement along the ground as the spider wheels rotate in response to motion of the tractor;
• wherein the arms of the spider wheel are equiangularly spaced to position the blades angularly apart such that each blade may engage and penetrate the ground behind a cultivator shank to form a series of longitudinally spaced pits therein in response to forward motion of the tractor;
• wherein each blade includes a ground penetrating cutting edge and parallel planar front and back faces, the back face lying in a radial plane passing through the transverse axis to lift and deposit soil rearward of the pits, forming mounds of soil directly behind the pits;
• wherein the spider wheels are angularly offset from one another about the shaft axis in succession along the shaft such that the shaft will transfer maximum weight of the spider wheels, shaft and blades carried above the ground surface to a minimum number of blades engaging the ground surface at any given time.
