A second belt conveyor is operable for conveying bulk materials upwardly and over another side of the cart. The dual unload system is automatically operable in a first mode operating the first belt conveyor and the unloading conveyor for conveying the bulk materials away from the cart, and in a second mode operating the second belt conveyor for conveying the bulk materials over the side of the cart.

The control of an apparatus within a grain holding device for feeding grain to an unloader conveyor operable for conveying the grain from the holding device, includes sensing a predetermined condition or conditions representative of capacity of the unloader conveyor for receiving grain, and adaptively controlling the apparatus for feeding grain to the unloader conveyor in advantageous varying manners responsive to the conditions, including to delay initiation of feeding until the receiving capacity is increased, and to match the grain feed to the capacity. The automatic control can be overridden, to allow user control of unloader speed, and can be configured to allow cleanout of the unloader conveyor.

The rear wheel drive assist includes a fluid operated drive motor coupled to the rear wheels of the machine, a diverter valve having a first position at which fluid flow is delivered from the pump to the work tool motor and a second position at which fluid flow is delivered from the pump to the drive motor, and a controller being configured to control the diverter valve to engage the rear wheel drive assist. The machine may be operated by engaging the pump and work tool motor, and then actuating the diverter valve to the second position to divert flow from the work tool motor to the drive motor.

A grain cart grain discharge including a pivotable discharge chute having a first position to discharge grain from a first side of a grain cart and a second position to discharge grain from an opposite side of the cart. The discharge chute is movably mounted on a guide and pivotable about the central axis of a grain supply auger mounted at the bottom of a grain hopper. A discharge head rotatably located on an end of the discharge chute opposite the supply auger and a control located on a vehicle, the control controlling the movement of the chute from the first position to the second position and controlling a rotational position of the discharge head without leaving the cab of the vehicle.

A flowable material delivering vehicle in combination with a material dispensing system including a fixed conveyor extending continuously from a position located adjacent a vehicle container outlet aperture to a position located adjacent a vehicle cab front end. A dispensing adapter is attached to the vehicle for receiving a portion of the flowable material when the latter emanates from the fixed conveyor. In one embodiment, the dispensing adapter includes a pivotable conveyor pivotally attached to the vehicle and a configuring mechanism. The configuring mechanism allows the pivotable conveyor to pivot between a stowed configuration wherein it lies in a generally proximal and parallel relationship relative to an edge of the vehicle and a working configuration wherein the pivotable conveyor extends away from the vehicle so as to allow discharging of the flowable material away from the vehicle. In another embodiment, the dispensing adapter includes a dispensing chute defining a chute inlet end positioned adjacent the fixed conveyor discharge section, a laterally and downwardly extending chute body and a chute outlet end positioned laterally relative to the vehicle.

A method and system are disclosed for moving and placing in hard to reach locations granular and other particulate material such as sand, gravel, earth and similar materials. The system includes an improved augar for moving the material and an improved rotary airlock mechanism designed to withstand the abrasive action of the particulate material and at the same time move the material several hundred feet through a flexible conduit for placement in a pre-designated location. A system and apparatus is also disclosed for transporting on one vehicle all of the devices needed at a remote site for operation the particulate placement system, including a front loader.

The chassis provides a hollow vertical frame connected to a floating extraction unit and two platforms which are formed by several panels transversally aligned to each side of an unloading pipe, which feeds a folding unloading tube. Between the extraction unit and the vertical frame, it is provided a spring unit and a hydraulic cylinder, both modifiers of the height. The extraction unit is formed by a central worm and two lateral worms, hydraulically adjustable in height, and two sweeping units. Each sweeping unit is connected to a plate over which there is supply for deviating the grain. Under it, there are settled the pipes of the hydraulic circuit, a scrapper of the inner wall of the silo-bag connected to the front edge of such plate, shaped as a flexible laminar body. Furthermore, it has an box bearing at least one floating brush, which bristles exceed the lower edge of the plate and they are in permanent contact with the ground of the silo-bag. The lateral worms provide a varying handhole of the opening and closing angles.

A hydraulic actuator assembly comprises a pair of hydraulic actuators having cylinders, pistons, and piston rods that are ganged together for extension of their respective piston rods in longitudinally opposite directions wherein at least one of the actuators comprises an anti-rotation mechanism that prevents rotation of the actuator assembly about its longitudinal axis. The anti-rotation mechanism comprises an axial anti-rotation rod rigidly attached to a cylinder having a non-circular cross-section slidably complementary to a non-circular aperture in a hollow piston rod. The piston rod can travel longitudinally along the anti-rotation rod, but is prevented from rotating by the non-circular cross-section.

A pivoting boot is disclosed for attachment to the unloading auger tube of combine harvesters, and serves as both a grain saving dam against unwanted grain spillage, and a directable spout. The boot permits evenly unloading grain onto, or completely filling, transportation vehicles or storage containers, without having to change the combine position, once it is staged for unloading.

An agricultural wagon for moving particulate material from within the wagon to a separate storage vessel is provided. The wagon includes a bin defined by walls. The wagon may also include one or two augers, such as a floor and lift auger for moving the material from within the bin to the storage vessel. The lift auger is movable relative to the storage bin such that it can dispense the material via a hood from either the left or right sides of the bin, such as at either the left or right and front corners of the bin. A mechanism including actuators and a guide can aid in moving the auger to the desired side for dispensing. The lift auger can further be folded in front of the bin when in a transport configuration, such as traveling on a road.

A control assembly provides autonomous control of various functions of a grain cart and/or provides guidance to an operator of the grain cart during the unloading of a grain cart. The control assembly collects input from one or more sensors including a speed sensor to monitor speed of a PTO that drives the unloading auger of the grain cart, a height sensor that measures the height of material discharged from the grain cart into a receptacle such as a grain truck, and/or a boundary sensors that measure lateral position of the grain cart relative to the receptacle or grain truck. Based on the input, the control assembly may vary the position of the discharge gate of the grain cart, or provide guidance to the operator to steer and position the grain cart relative to an adjacent grain truck.
