A header transport steering system is provided that allows the tongue of the header transport to pivot and translates the movement of the tongue to all of the wheels of the header transport. Front steering linkages are coupled to the tongue, and are configured to oscillate front wheels in response to rotation of the tongue. Walking tandem beams are connected to the frame and are configured to rotate in height with respect to the frame.

A device detects a trigger to dispense a product at a dispense point using a tool operably coupled to a tractor. In response to detecting the trigger, the device determines a delay time between commanding the tool to dispense the product and the product actually being dispensed, and determines a release point based on operating parameters of the tractor, the release point being a point at which the tractor is predicted to be an amount of time away from the dispense point equal to the delay time. The device determines that the tractor has reached the release point, and commands the tool to dispense the product, where the product reaches the dispense point based on the delay time.

An articulated tractor comprises a front frame, a rear frame articulated to the front frame by a central articulation, and a pivotable hitch carried by one of the front frame and the rear frame. The hitch is pivoted during steering. Front wheels are offset from the rear part of the tractor.

The present invention relates to mobile machinery such as an agricultural tractor comprising a three-point hitch for the connection and use of working implements cultivating or excavating the earth and other duties involved in the industry of farming or grading excavation. The disclosed invention modifies and improves the conventional three-point hitch in use today. The disclosed invention modifies the three-point hitch by adding extending and retracting implement-actuators attachable to the existing bottom-lift-arms, therefore supplanting, but still using the existing bottom-lift-arms on the three-point hitch. The implement-actuators assist the implement in correcting the implements centerline when the tractor centerline is off a predetermined centerline path. In addition, the extending of the implement-actuators proportionally, inversely and simultaneously can correct the pivot point of the implement to match the pivot point of the tractor while the tractor performs turns during the working use of the implement.

An agricultural mower system includes: a towing vehicle including an engine and a tongue coupler and defining a towing centerline; a mower including a frame carrying cutters and pivotably coupled to a tongue that is pivotably coupled to the tongue coupler, the frame defining a mower centerline that is offset from the towing centerline, the tongue defining a towing angle with respect to the towing centerline and a mower angle with respect to the mower centerline; a mower angle actuator coupled to the tongue and the frame; and a controller configured to: determine the towing angle has changed by a change amount relative to a defined towing angle; determine a turn compensation amount for the mower angle as a function of the change amount and a constant; and output a compensation signal to cause the mower angle actuator to adjust the mower angle by the determined turn compensation amount.

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.

An implement guidance module is provided for positioning a drawn implement as the implement is pulled by a vehicle traveling along a desired path of movement, the vehicle having a connection point for receiving a hitch. The module includes a module main frame having a first end configured for connection to the vehicle connection point, and a second end configured for connection to the implement, the main frame having a longitudinal axis, and having a pivot mount connected to the second end with an implement mounting plate pivoting relative to the module main frame about a pivot axis perpendicular to the longitudinal axis. A vehicle mounting plate defines the first end of the module main frame, and the implement mounting plate defines the second end of the module main frame.

Systems and methods are provided for controlling operation of an agricultural vehicle-implement combination. An orientation of the vehicle, the implement and/or the vehicle-implement combination is used to determine whether an adjustment in a lateral position of the implement is required. An actuator mechanism is provided for controlling the lateral position of the implement in accordance with any determined adjustment.

An implement operating apparatus has a U-shaped drive frame supported on drive wheels, each pivotally mounted about a vertical wheel pivot axis. A steering control selectively pivots each drive wheel. A power source is connected through a drive control to rotate the drive wheels in either direction. First and second implements are configured to perform implement operations and to rest on the ground and when the drive frame is maneuvered to an implement loading position with respect to each implement, the implement is connectable to the drive frame and movable to an operating position supported by the drive frame. When the implement is in the operating position, the steering and drive controls are operative to move and steer the drive frame and implement along a first travel path or a second travel path oriented generally perpendicular to the first travel path.

A yaw rate is sensed on a towing vehicle that is towing an air seeder. The sensed yaw rate is used to predict a future yaw rate on a planting implement of the air seeder. An application rate of material is varied across the application implement based upon the predicted yaw rate across the implement.
