Abstract

A harrow implement comprises of a tool bar with harrow sections attached in which each section is supported by one or more hydraulic cylinders mounted such that the cylinders force translated through the section provides a substantially constant force to the ground throughout the cylinders travel. A hydraulic pressure control is used such that the hydraulic oil on both sides of each hydraulic cylinder is regulated. The control is operated to vary the pressure differential between sides of the cylinder allowing a continuous range of ground force between zero (sections lifted) and a maximum, transferring tool bar mass to the sections.

Abstract

A towable agricultural implement, having a center frame and two wing frames pivotally coupled on the center frame to move between a field frame position extending laterally outward and a range of transport positions extending generally rearward, further includes a transport wheel on each wing frame that is pivotal about an upright steering axis through a range of wheel positions including a neutral transport wheel position for rolling forwardly. Each transport wheel is pivotal from the neutral transport wheel position in either one of two opposing steering directions under control of a steering actuator through an overall range of greater than 90 degrees. The wheels can be steered in a common direction during transport. A control system can also attempt to maintain a constant angle between the center section and the wings to allow reversing while in transport mode.

Abstract

A control apparatus controls the hydraulic connection between self steering wheels on a trailing vehicle, for example a grain cart, and the hydraulic system of a utility vehicle, for example a tractor, towing the trailing vehicle. An auxiliary circuit on the trailing vehicle forms a continuous loop receiving in series one or more wheel actuators associated with the self steering wheels. A valve arrangement is operable in a locked state or unlocked state in which the continuous loop is isolated from the tractor to prevent or allow a flow of fluid in the continuous loop regardless of the state of the tractor hydraulics. In a manual state, the flow in the loop is dependent upon the tractor hydraulics. In an automatic mode, a controller automatically operates the valve arrangement between the locked and unlocked states dependent upon one or more sensed operating conditions of the trailing vehicle.

Abstract

In a grain cart having an auger fold actuator, a gate actuator, and at least one spout actuator, a grain cart control system has an input device received within an operator cab to generate command signals responsive to operator commands, an electronic controller operatively associated with selected actuators of the grain cart, a valve actuator connected to each valve of the selected actuators of the grain cart, and stored programmable criteria to generate activation signals for the valve actuators in response to the command signals. Each mechanical function that is controlled also has a rotary potentiometer for positional feedback. To actuate any sequence, a joystick will send commands to the controller to activate a sequence. Since the controls according to the present invention are driven by a logic-based controller, various functions can be automated.

Abstract

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.

Abstract

A soil spreading scraper device has a cutting blade to cut soil from the ground and a rotating impeller member for spreading the cut soil as the frame is displaced forwardly. The impeller member includes a main disc body and a plurality of impeller blades on the main disc body which are pivotal relative to the body between a working position in which the blade body extends in a direction of the impeller axis away from the main disc body and a deflected position in which the blade body extends in a circumferential direction of the disc body in a trailing relationship relative to the pivot axis of the blade body. An actuating assembly resists displacement of the blade body into the deflected position until pressure on the paddle exceeds a prescribed holding force. A spring biases the body to return to the working position.

Abstract

A harrow includes plural hydraulic actuators to displace respective working elements between opposing first and second positions. The actuators are connected in series in a phasing relationship to define one or more hydraulic circuits. Each circuit includes a lead actuator mounted in a first orientation to displace the respective working elements in a first direction when extended and a secondary actuator in series with the lead actuator in an opposing second orientation to displace the respective working elements in the first direction when retracted. One of the ports of the secondary actuator is coupled to the same one of the ports of the lead actuator such that all of the working elements are simultaneously displaced in a common direction when supplying hydraulic fluid under pressure to the lead actuator. Additional actuators may be similarly connected in series in alternating orientations with the lead and secondary actuators of each circuit.

Abstract

A soil spreading scraper device comprises a cutting blade for cutting a top layer of soil from the ground, a kicker for throwing the cut soil rearward from the cutting blade, and an impeller member rotatable within a plane of rotation extending upward and rearward from the cutting blade for capturing the soil thrown by the kicker and spreading the cut soil generally radially outward relative to an axis of rotation of the impeller. A gearbox which receives power from a power takeoff of a towing vehicle directly drives the rotation of the impeller member in the preferred embodiment. The blades of the impeller members may include recessed portions adjacent the impeller axis in some embodiments to encourage soil being received in the impeller member even at higher rates of rotation, for example in the range of 250 to 320 RPM.
