Abstract: A machine and method for collecting rocks in fields and then for dumping these rocks in a row for easier pickup or for storage. The machine includes one or more rock collectors for receiving rocks along with soil, smaller rocks and field debris that may accompany the rocks, and for screening out soil, field debris and smaller rocks that are small enough to pass through gaps between the grates of the rock collectors. The machine also includes rock lifter plates that assist the lifting of rocks from the field up onto the rock collectors for screening and collection. A further embodiment of the machine includes a rock collector unloader mechanism for raising the rock collectors thereby unloading the collected rocks roughly in rows. These rows may be formed off the field, or picked up more easily by hand or with a conventional row-collecting rock picker, and then removed from the field.

Abstract: A ground raking attachment for bucket-equipped tractor includes a toothed, cylindrical rotor which works the soil and at the same time rakes the ground free of rocks, refuse, roots, sticks and other debris which is transferred to the tractor bucket by the action of the rotor.

Abstract: A wheel mounted pull type chassis includes a side hitch bar for securement to a tractor or the like. A reel assembly is journalled for rotation and is situated transversely at the front of the chassis and picks up rocks, stones, dirt, etc. and deposits same on an upwardly and rearwardly inclining slotted apron with the teeth of the pick up bars at the reel passing through the apron teeth and depositing the picked up material into a screening wheel journalled for rotation about a generally horizontal but inclined longitudinal axis so that the wheel is tipped rearwardly from the vertical. The periphery of the wheel is slotted. It is supported upon a pair of spaced apart support wheels one wheel of which is driven and which engage a track around the outer periphery of the wheel. Three equidistantly spaced rear support wheels engage the rear of the periphery of the wheel for added support.

Abstract: A root picker includes a main frame supporting within it a triangular picker frame pivoted on the main frame at one apex with a lower and rearwardly positioned apex supporting a picker roller which is rotated to pick stones from the ground. A conveyor chain supporting transverse bars with outwardly extending teeth is pivotally mounted adjacent the third apex of the frame upwardly and rearwardly of the picker roller so that the chain turns around an axis at a position alongside the picker roller to lift rocks between the conveyor chain and the picker roller onto a surface which leads up to a bucket. The frame pivots to lift the conveyor chain and the picker roller away from the ground and also the conveyor chain is pivotal relative to the frame to increase the spacing between the chain and the picker roller. Rotating sweep drums are positioned forwardly and outwardly of the frame to pick and sweep rocks into the picker roller.

Abstract: A ground-raking attachment adapts bucket-equipped tractors for raking a ground surface free of rocks, refuse, roots, sticks and other debris. The attachment includes a frame and means for pivotally mounting the frame on a tractor bucket. The frame mounts at least one pair of motor driven, rotatable shafts mounting a plurality of rake teeth arranged for raking debris from the ground and progressively advancing it into the bucket. A frame drive is connected to the bucket for angularly adjusting it to selected positions relative to the ground.

Abstract: A beach cleaning apparatus comprises a forward assembly operatively connected to a trailer member, the forward assembly having a body portion rollably supported on a pair of spaced wheels and adapted for connection to a towing vehicle. A vertical member rotatable about a vertical axis extends upwardly from the body portion and has a rearwardly extending lever arm assembly pivotably secured thereto for movement about a horizontal axis. A winch on the forward assembly is connected to the lever arm assembly for effecting pivotal movement thereof. The free ends of the lever arm assembly are connected to the forward end of the trailer member, which consists of a rectangular container having a bed which comprises an interchangeable screen member adjacent its forward end and an interchangeable ground engaging blade member extending outwardly of the forward end.
