A work machine that has an implement coupled to the frame of the work machine, a first sensor coupled to the implement, a controller, and an implement position system that couples the implement to the frame. The first sensor identifies the orientation of the implement along more than one axis and the controller manipulates the implement position system to reposition the implement relative to the frame based on the orientation of the implement identified by the first sensor.

A hydraulic system for controlling a pair of steerable caster wheels includes a left steering command valve, a right steering command valve, and a rear steering control valve. A supply pressure fluid circuit interconnects a pressure source and the rear steering control valve. A command valve supply fluid circuit interconnects the rear steering control valve with both the right steering command valve and the left steering command valve. A left side steering fluid circuit interconnects a left side actuator and the left steering command valve. A right side steering fluid circuit interconnects a right side actuator and the right steering command valve. A fluidic tie rod fluid circuit interconnects both the left side actuator and the right side actuator with the rear steering control valve. A tank return fluid circuit interconnects the rear steering control valve, the left and right steering command valves, and a tank.

A knotter drive apparatus for a baler includes a knotter gear drive shaft having a drive shaft axis and a shaft outside diameter. A plurality of knotter assemblies are mounted on the knotter gear drive shaft. Each assembly includes a first knotter gear sector including a first sector hub portion and a first sector radial portion. The first sector hub portion includes a central passage at least partly defined in the first sector hub portion for receiving the knotter gear drive shaft. The first sector radial portion extends radially outward from the first sector hub portion relative to the drive shaft axis, and has defined thereon a plurality of intermittent gear tooth segments. The first sector hub portion has a circumferential gap defined therein greater than the shaft outside diameter such that the first knotter gear sector is removable radially, relative to the drive shaft axis, from the knotter gear drive shaft.

Intermittent knotter gear

A bale monitoring system includes an imaging device that is operable to capture a stereoscopic image of a bale. A computing compares the stereoscopic image of the bale to a three-dimensional standard to identify a deviation of the bale from the three-dimensional standard. The computing device may then assign the bale a shape quality score based on the deviation of the bale from the three-dimensional standard. The shape quality score may indicate a magnitude of the deviation of the bale from the three-dimensional standard. Additionally, the stereoscopic image may be analyzed to identify characteristics of the bale, such as a broken wrap material or an improperly formed bale.

Bale shape monitoring system

A vehicle includes a rear steering system and a front differential hydraulic drive system. A first front drive control valve is operable to output a defined fluid flow in response to a steering command input. A second front drive control valve is operable to selectively divert a portion of the defined fluid flow output from the first front drive control valve. When the vehicle is operating in a pre-defined condition, a steering controller may control the second front drive control valve to divert a portion of the defined fluid flow from the first front drive control valve to define a reduced fluid flow, which is communicated to the front differential hydraulic drive system, to reduce a steering ratio of the front differential hydraulic drive system relative to the rear steering system, to desensitize steering provided by the front differential hydraulic drive system.

A ground contour sensing system and method for a vehicle with a mowing head. The system includes a sensor system that measures a ground contour in front of the mowing head, and generates contour measurement signals; and a controller that determines whether to move the mowing head based on the contour measurement signals, and generates movement commands for the mowing head when it determines to move the mowing head. The mowing head can include tilt and lift cylinders, and the controller can determine whether to move the mowing head using the tilt or lift cylinders. The sensor system can include a pivot arm that moves in response to changes in the ground contour, and an angle sensor that measures an angle of the pivot arm. There can be one or more sensor systems positioned between the right and left sides of the mowing head.

A float cylinder is coupled to an accumulator by a first hydraulic fluid conduit. The float cylinder and accumulator are coupled to apply a float force on a header main frame.

Controlled or tuned float on an agricultural harvester to modify float response

A system for forecasting the drying of an agricultural crop includes an electronic processor configured to receive weather data associated with an agricultural field and receive an agricultural field parameter from a field sensor associated with the agricultural field. The electronic processor is also configured to determine a drying score for each of a plurality of harvest times based on the weather data and the agricultural field parameter. The electronic processor is also configured to determine a recommended harvest time for harvesting the agricultural crop based on the drying score, wherein the recommended harvest time is included in the plurality of harvest times. The electronic processor is also configured to output a forecast for the agricultural crop for display to a user, wherein the forecast includes the drying score and the recommended harvest time for harvesting the agricultural crop.

A hydraulic system for controlling at least one steerable caster wheel of an agricultural machine includes a first actuator having a piston and including an inboard fluid port for supplying fluid to a first side of the piston to move the piston in a first direction, and an outboard fluid port for supplying fluid to a second side of the piston to move the piston in a second direction. A first fluid pressure equalizer is fluidically coupled to the first side actuator and operable to equalize fluid pressure over a period of time between the first side and the second side of the piston of the first side actuator.

A mower-conditioner includes first and second conditioning rolls, adjustment assembly, and a linkage. The adjustment assembly includes a first member having a first helical surface and a second member having a second helical surface in contact with each other. The linkage is coupled between the at least one adjustment assembly and the first conditioning roll. The rotation of the at least one adjustment assembly about a pivot axis causes the first conditioning roll to move via the linkage, which adjusts the distance between the first and second conditioning rolls.

The first and second conditioning rolls are spaced apart a distance. The at least one eccentric is coupled to the mower-conditioner. The lever is coupled between the eccentric assembly and the first conditioning roll. The rotation of the at least one eccentric about a pivot axis causes the first conditioning roll to move via the lever, which adjusts the distance between the first and second conditioning rolls.
