A lateral tilt control system for an agricultural harvester may include first and second tilt cylinders coupled between a support structure and an implement of the harvester. The first tilt cylinder may include a first cap-side chamber and a first rod-side chamber and the second tilt cylinder may include a second cap-side chamber and a second rod-side chamber. The system may also include a first fluid line providing a flow path between the first cap-side chamber and the second rod-side chamber and a second fluid line providing a flow path between the first rod-side chamber and the second cap-side chamber. Additionally, the system may include a pressure relief valve coupled between the first and second fluid lines to allow fluid to be transferred between the first and second fluid lines when a fluid pressure within either fluid line exceeds a relief pressure setting.

An agricultural vehicle includes a chassis and a header system carried by the chassis. The header system includes a frame; a cutter carried by the frame; a cutter sensor associated with the cutter which outputs a cutter height signal; a gauge wheel carried by the frame behind the cutter; a wheel sensor associated with the gauge wheel which outputs a wheel position signal; an actuator system including actuators which can adjust a height and/or a tilt angle of the frame; and a controller electrically coupled to the cutter height sensor, the wheel sensor and the actuator system. The controller is configured to: receive the cutter height signal; receive the wheel position signal; compare the cutter height signal and the wheel position signal to determine a terrain irregularity is present; and activate one or more actuators to adjust the frame in response to determining the terrain irregularity is present.

A combine harvester includes a belt cutting unit comprising a center belt for conveying harvest to an intake roller and/or to an intake channel of a grain conveyor, and a transverse conveyor belt disposed each on the left-hand side and the right-hand side of the center belt, to convey harvest to the center belt. The center belt, left-hand and right-hand transverse conveyor belts are behind a cutter bar, seen in the direction of travel, with each being operated with an individual belt speed. The combine harvester and/or belt cutting unit has a control unit configured to automatically control the belt speeds of the left-hand and right-hand transverse conveyor belts as a function of a forward travel speed, and the belt speeds of the center belt as a function of the forward travel speed or as a function of the belt speeds of the left-hand and right-hand transverse conveyor belts.

An agricultural harvester including a feeder. The feeder is pivotally mounted to an intermediate frame with respect to a first axis of motion. The intermediate frame is pivotally mounted to a header mounting frame with respect to a second axis of motion. Pivoting around the first axis of motion and the second axis of motion allows a fore-aft movement and a lateral tilt movement. At least one lateral tilt actuator is provided to actuate the header mounting frame in the lateral tilt movement. At least two fore-aft actuators are provided for extending between a first set of mounting positions at the feeder and a second set of mounting positions at the header mounting frame to actuate the header mounting frame in the fore-aft movement.

An agricultural method for automatically controlling a position of a harvesting implement of an agricultural harvester, where the harvesting implement may be movably supported relative to a chassis of the agricultural harvester, and where a cab may be movably supported relative to the chassis, may include receiving inertial movement data from an implement-based inertial measurement unit (IMU) supported on the harvesting implement and inertial movement data from a vehicle-based IMU supported on at least one of the cab or the chassis of the agricultural harvester. The method may further include determining a relative movement parameter of the harvesting implement relative to the at least one of the cab or the chassis based at least in part on the inertial movement data. Additionally, the method may include controlling an operation of an implement actuator based at least in part on the relative movement parameter.

An agricultural harvester including a chassis and a header for gathering a crop and feeding it into the agricultural harvester. The agricultural harvester further includes a threshing and separating system, a grain cleaning system for separating grain from MOG, and a feeder housing for moving the crop gathered by the header from the header into the threshing and separating system. The agricultural harvester further includes a header tilt mechanism that allows the header to tilt in order to follow ground contours. The header tilt mechanism may use a face plate movably attached to the feeder housing. The header tilt mechanism includes at least one straight line linkage movably connecting the header to the feeder housing. The feeder housing or header tilt mechanism may be provided with hydraulic cylinders or pressure controlling or limiting arrangements.

A suspended mower device is disclosed which is a tool engineered explicitly for efficiently mowing terrains with challenging attributes. The suspended mower device comprises a compact tractor or skid steer that supports an attachment component configured to support a mower over inclined areas. The attachment component comprises a dual unistrut or dual square tubing and chains which allow the mower component to hover. As the mower hovers above the surface, the cutting blades consistently engage with the grass, ensuring an even cut. Further, a set of wheels affixed to the mower offer stabilization on all terrains. Additionally, the compact tractor has a hydrostatic drive, which acts to control the mower's speed and the tractor's bucket control is used to adjust the mower's height, angle, and orientation.

A method for adjusting a header mounted on an agricultural harvester. The header includes a central section and at least one side wing section. The at least one side wing section extends between an inner portion and an outer portion, where the inner portion of the at least one side wing section is pivotally coupled to the central section. A ground engaging device is mounted on the at least one side wing section adjacent the outer portion. The ground engaging device has an adjustable height. The method comprises the steps of determining a flex position of the at least one side wing section relative to the central section, determining whether the flex position of the at least one side wing section exceeds a first threshold, and if it is determined that the flex position of the at least one side wing section exceeds the first threshold, decreasing the flex position.
