Abstract: Apparatus for the moving and spreading of loose materials, such as dirt. A frame attaches to the three point hitch on a tractor. A bucket is rotatably attached to the frame, and a blade is attached to the frame and positioned within the bucket so as to substantially span the height and width of the bucket interior. In a first position, the bottom wall of the bucket is positioned substantially horizontally. The tractor moves so as to insert the open mouth of the bucket into a quantity of loose material, then raises the bucket and moves to a desired location. The bucket is lowered so that drag members on the bucket contact the ground; forward movement of the tractor causes the bucket to rotate, creating an opening between the bucket and the blade and causing the loose material to flow out of the bucket onto the ground.

Abstract: A handling apparatus is provided that attaches to a three-point hitch of a farm implement/tractor. The apparatus allows for engaging multiple bales in a field while the tractor is driven in a forward direction. The bales are engaged while they are disposed beside the tractor such that they are in view of the operator. Once bales are engaged, the apparatus allows for rotating the bales from a position beside the tractor to a position behind the tractor. This allows, inter alia, the tractor to pass through openings (e.g., gates or doors) while carrying multiple bales.

Abstract: A bale mover is disclosed which includes a frame having a hitch mounted thereon which may be attached to the three-point hitch of the tractor or to the front end of a front-end loader mounted on the tractor.

The support deck (13) includes a cross conveyor (21) for discharging the bale (B) laterally for stock feeding.

Abstract: Methods for operating robotic devices (i.e., “robots”) that employ adaptive behavior relative to neighboring robots and external (e.g., environmental) conditions. Each robot is capable of receiving, processing, and acting on one or more multi-device primitive commands that describe a task the robot will perform in response to other robots and the external conditions. The commands facilitate a distributed command and control structure, relieving a central apparatus or operator from the need to monitor the progress of each robot. This virtually eliminates the corresponding constraint on the maximum number of robots that can be deployed to perform a task (e.g., data collection, mapping, searching). By increasing the number of robots, the efficiency in completing the task is also increased.

According to the invention means are provided that for a pendulous movement to the right the lower right hydraulic cylinder and the upper left hydraulic cylinder extend synchronously and the lower left hydraulic cylinder and the upper right hydraulic cylinder are retracted synchronously. For a pendulous movement to the left the hydraulic cylinders operate in the opposite direction.

Abstract: A multi-purpose log-handling tool for attachment to the three-point hitch of a tractor or other vehicle includes a boom and an inverted U-shaped frame containing a number of apertures to which accessory tools may be attached.

The apertures are preferably longitudinally arranged along a flange affixed to the bottom of the boom. Multiple apertures permit the simultaneous use of more than one tool, which might include logging tongs, chains, or winches. A flexible assembly for coupling the boom to the hydraulic piston accommodates for skewing action as a log is dragged and thereby reduces potential for damage to the log-handling tool.

The rest surface is movable so as to enable placement of the hay bale's center of gravity on the vehicle.

Abstract: A multi-purpose log-handling tool for attachment to the three-point hitch of a tractor or other vehicle includes a boom and an inverted U-shaped frame containing a number of apertures to which accessory tools may be attached. The boom and the frame are connected to the tractor and at one of the apertures to permit the outer end of the boom to be lowered and raised by an operator controlling one or more hydraulic pistons.
