A prescribed feedrate of material through the mobile harvesting machine and an actual feedrate of material through the mobile harvesting machine are detected, and a feedrate difference between the prescribed feedrate and the actual feedrate is identified. Wheel slippage of the mobile harvesting machine is also detected. Based on the feedrate difference between the prescribed feedrate and the actual feedrate and based on the detected wheel slippage, a speed control signal that controls speed of the mobile harvesting machine is generated.

A spreader of a combine for conveying crop residue rearwardly from a rotor assembly includes a frame coupled to the combine and has a top portion adapted to receive a portion of crop residue during a harvesting operation. An impellor includes one or more blades for rotatably conveying crop residue rearwardly, and an actuator is controllably moved between an extended position and a retracted position. The actuator is pivotally coupled to the combine. A linkage assembly is pivotally coupled to the actuator at one end and to the frame at another end. The spreader is disposable in a first position when the actuator is in the extended position, and the spreader is disposable in a second position when the actuator is in the retracted position. A movement from the extended position to the retracted position induces pivotal movement of the spreader from the first position to the second position.

A tilt-sensing apparatus for a vehicle, comprising: a controller; and a motion tracker, wherein the controller is configured for communication with the motion tracker and a display, wherein the motion tracker is configured for attachment to a vehicle at a position remote to the display and comprises a first tilt sensor configured to measure a first tilt angle with respect to a first axis and a second tilt sensor configured to measure a second tilt angle with respect to a second axis, wherein the controller is configured to receive data via an output of the motion tracker, said data comprising the first tilt angle and the second tilt angle, and communicate an instruction to the display to display a graphical representation indicative of the first tilt angle and the second tilt angle, and associated method.

A track system for traction of a vehicle (e.g., an agricultural vehicle). The track system is connectable to an axle of the vehicle. The track system comprises a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track comprises elastomeric material to flex around the track-engaging assembly. The track-engaging assembly comprises a drive wheel for driving the track, a plurality of idler wheels for contacting a bottom run of the track, and a bogie carrying the idler wheels. The track system comprises a transmission for transmitting power from the axle of the vehicle to the drive wheel such that a rotational speed of the drive wheel is different from a rotational speed of the axle of the vehicle. The track system comprises a connector disposed between the transmission and the bogie such that the bogie is movable (e.g., pivotable) relative to the transmission. The connector may be disposed below an output shaft of the transmission.

A grass management system includes a prohibition determination circuit and a baler. The prohibition determination circuit is configured to determine a prohibition position. The baler is configured to acquire the prohibition position from the prohibition determination circuit, and eject a bale of grass at a position except for the prohibition position.

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.

Robotic work tool (100) configured for improved turning in a slope (S), said robotic work tool comprising a slope detector (190), at least one magnetic field sensor (170), a controller (110), and at least two driving wheels (130), the robotic work tool (100) being configured to detect a boundary wire (250) and in response thereto determine if the robotic work tool (100) is in a slope (S), and if so, perform a turn by rotating each wheel (130) at a different speed thereby reducing a risk of the robotic work tool (100) getting stuck.
