An articulated rake assembly attachable to an excavating vehicle having a bucket. The rake assembly has a rake mechanism adapted and constructed to retain material having a certain size. A reciprocating mechanism operationally connects the rake mechanism to the bucket of the vehicle, and is adapted and constructed to selectively reciprocate the rake mechanism with respect to the bucket, thereby selectively retaining material. The rake mechanism configurable to have either or both a push orientation and a gather orientation.

An agricultural rock collection and rock rowing machine and method is disclosed 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. The rock collector unloader mechanism may be attached to a trailer frame portion of the machine, the trailer frame serving to pull the rock collectors when the trailer frame is attached to a tractor or suitable pulling machine.

A self-propelled stall cleaning apparatus has a frame assembly, a pair of drive wheels, a motor attached to the assembly for driving the drive wheels and a motor driven collector head. The collector head has a pivoting fork with tines for collecting manure and debris. The fork picks up the manure and debris and tosses it onto a sifting conveyor. The sifting conveyor separates the manure from the bedding and delivers the manure to a lift conveyor which drops the manure into a collection bin. The collection bin is moveable from a stowed position to a dumping position and then back to a stowed position.

The stalk eliminator chops stalks, uproots stalks, and re-chops stalks. The apparatus includes a front stalk chopper on a rotating cylinder with angularly attached blades. A plow tool attaches to the apparatus and provides a subsoiler wing behind and under the front stalk chopper. A rear stalk chopper on a rotating cylinder with angularly attached blades follows the plow tool.

A stalk puller to be used with or without a mower/shredder utilizes a pair of independently mounted discs converging along their lower edge to grasp and pull stalks from the ground as the stalk puller is moved down the row by a prime mover. At least one of the discs is urged against the other by a spring such that the associated disc may allow rocks and debris to pass between the discs without damage. The spring mounting reduces adjustments due to normal wear as well as damage from debris.

An object-collection system is disclosed. The system including a vehicle connected to a bucket, a camera connected to the vehicle, and an object picking assembly configured to pick up objects off of ground. The system further includes a processor that obtains object information for identified objects, guides the object-collection system over a target geographical area toward the identified objects based on the object information, captures images of the ground relative to the object picker as the object-collection system is guided towards the identified objects, identifies a target object in the images, tracks movement of the target object across the images as the object-collection system is guided towards the identified objects, and employs the tracked movement of the target object to instruct the object picker to pick up the target object.
