A coupling device for attaching a power lift of a tractor to an attachment includes a link mounting region having coupling units for the articulation of an upper link and two lower links of the power lift, and an apparatus mounting region for fixing the attachment. A coupling unit assigned to the upper link is movable in a translatory manner in a vertical direction running perpendicular to a transverse direction. The coupling units are movably disposed on a device base of the coupling device, and the coupling units assigned to the two lower links are movable in a translatory manner in the transverse direction.

A sensor arrangement for an agricultural vehicle includes a first electro-optical sensor including a first field of view having an optical axis, and a second electro-optical sensor including a second field of view having an optical axis. The first and second sensors are spaced apart from one another and oriented such that the optical axes of the two sensors intersect at a distance from the two sensors.

An agricultural machine includes a vehicle body, a travel switch operable to issue a command to start autonomous travel of the vehicle body, and an autonomous travel controller to perform autonomous travel of the vehicle body based on a planned travel line when the command is issued. When the command is issued by operating the travel switch, if at least one of a positional deviation between the planned travel line that is selected and the vehicle body and an orientational deviation between the planned travel line and an orientation of the vehicle body is greater than or equal to a corresponding one of respective first thresholds, the autonomous travel controller is configured or programmed to perform line alignment to make the positional deviation and the orientational deviation less than the respective first thresholds.

An agricultural machine includes a vehicle body, an obstacle detector to detect obstacles, an autonomous travel controller to perform autonomous travel of the vehicle body, the autonomous travel controller being configured or programmed to, when performing the autonomous travel, stop the vehicle body based on detection information about an obstacle detected by the obstacle detector, and a mode switch to switch a mode during the autonomous travel in an agricultural field between an effective mode in which the stopping of the vehicle body based on the detection information is allowed and an ineffective mode in which the stopping of the vehicle body based on the detection information is not allowed.

An automatic travel system for a work vehicle has an automatic travel control unit that causes a work vehicle, which is provided with an obstacle detection unit that detects obstacles, to travel automatically. The obstacle detection unit includes imaging units and active sensors. When the obstacle detection unit detects an obstacle based on information from the imaging units, and the separation distance from the obstacle is acquired based on information from the active sensors, the automatic travel control unit executes a first collision avoidance control for avoiding a collision between the work vehicle and the obstacle, on the basis of the separation distance from the obstacle acquired based on the information from the active sensors.

The invention relates to a method for cultivating row crops (200), comprising the following steps: sensor and satellite based recording of locations and/or courses of rows of plants (202a-202l ) while a first cultivation measure is carried out on a row crop (200) by means of an agricultural plant cultivation device (10) and controlling the movement and/or operation of an agricultural plant cultivation device (10) while a second cultivation measure is carried out on the row crop (200) based on the recorded locations and/or courses of the rows of plants (202a-2021).

A crop detection system and method of using the same includes a machine vision system mounted to a mobile vehicle. The machine vision system includes an information capturing device connected to a computer having a processor and memory. The memory includes stored crop and field information. Positioning members are mounted to an extend forward of the mobile structure. The information capturing device includes a camera, a sensor, a transceiver and/or a stereo sensor configuration and is positioned to sense the presence, size, location and orientation of characteristics of a crop.

A hood of a tractor including a front grill, a light unit, and an upper cover is provided with a center pillar. The front grill is attached to the center pillar, the light unit is attached to the front grill, and the upper cover is supported by the center pillar. The hood is further provided with a side frame and a lower cover, where the side frame is attached to the center pillar, and the lower cover is attached to at least the upper cover and the side frame.

A device to determine a height disparity between features of an image includes a memory including instructions and processing circuitry. The processing circuitry is configured by the instructions to obtain an image including a first repetitive feature and a second repetitive feature. The processing circuitry is further configured by the instructions to determine a distribution of pixels in a first area of the image, where the first area includes an occurrence of the repetitive features, and to determine a distribution of pixels in a second area of the image, where the second area includes another occurrence of the repetitive features. The processing circuitry is further configured by the instructions to evaluate the distribution of pixels in the first area and the distribution of pixels in the second area to determine a height difference between the first repetitive feature and the second repetitive feature.

Embodiments of the present disclosure relate generally to generating and utilizing three-dimensional terrain maps for vehicular control. Other embodiments may be described and/or claimed.
