Abstract: This rock picker invention is a towable farm implement which is capable of removing rocks from a farm field. A plurality of buckets scoop up quantities of soil as the rock picker is towed by a tractor. The buckets are mounted on a pair of cables which pass over guide wheels. The cables are forced to move by a power source so that the buckets are forced into, across and out of the ground. The guide wheels are mounted on axles on a conveyor frame which allows the buckets and cables to be lifted to a transport position and which allows the angle of attack between the buckets and the ground surface to be varied. The buckets are equipped with openings and shaped such that soil falls from the buckets when the buckets are lifted. The cables are guided such that the buckets are caused to invert and dump the rocks collected into a hopper. The hopper is equipped with a lifting linkage to allow transfer and disposal of rocks collected.

Abstract: An elongated frame is provided including front and rear ends. The rear end portion of the frame includes rear wheeled transverse axle structure supported from the frame for adjustable angular displacement in a horizontal plane relative to the frame. The front end portion of the frame includes towing structure supported from the frame for adjustable shifting transversely thereof and operative, in conjunction with the adjustable axle structure, to establish an angularly adjusted towed relationship of said elongated frame behind a towing vehicle to which the towing structure is attached. The frame further includes longitudinally extending and traversely facing rake structure.
