A mobile machine movable between multiple rows of trees includes at least two LiDAR sensors to output two-dimensional or three-dimensional point clouds data indicating a distribution of objects in a surrounding environment of the mobile machine, a storage to store environment map data indicating a distribution of trunks of the multiple rows of trees, a localization processor, and a controller to control movement of the mobile machine in accordance with a position of the mobile machine as estimated by the localization processor. The localization processor is configured or programmed to detect the trunks of the rows of trees in the surrounding environment of the mobile machine based on the point clouds data that is repeatedly output from the at least two LiDAR sensors while the mobile machine is moving, and to perform matching between the detected trunks of the rows of trees and the environment map data to estimate a position of the mobile machine.

A control system for a work vehicle that performs auto-steer driving includes a storage to store a target path for the work vehicle, and a controller configured or programmed to control steering of the work vehicle so that the work vehicle travels along the target path based on a position of the work vehicle identified by a position identifier and the target path stored in the storage. The target path includes parallel main paths and one or more turning paths interconnecting the plurality of main paths. When the work vehicle is turning along one of the turning paths via automatic steering, if the position of the work vehicle becomes deviated from the turning path by more than a reference distance, the controller is configured or programmed to cause an alarm generator to output an alarm.

Work vehicle and control system for work vehicle

An agricultural machine includes one or more tires, a detector to detect a low pressure state in which a pressure of one of the tires is lower than a reference range or a high pressure state in which the tire pressure is higher than the reference range, and a controller to control an operation of at least one of the agricultural machine and an additional agricultural machine to be linked to the agricultural machine. One of the agricultural machine and the additional agricultural machine is a work vehicle that is capable of self-driving, and the other one is an implement to be linked to the work vehicle. The controller causes, in response to detection of the low or high pressure state, at least one of the agricultural machines to perform a specific operation that is different from an operation to be performed when the pressure is in the reference range.

A control system to control a work machine and a traveling vehicle traveling with the work machine, includes a first communication device and a second communication device each of which controls operation of the traveling vehicle and at least one of which includes an authenticator to authenticate the work machine by communicating with a third communication device to control operation of the work machine, and a notifier to notify the other one of the first communication device and the second communication device that the authenticator succeeded in authentication, the first communication device and the second communication device each being prohibited, unless the authenticator succeeds in authentication, from at least controlling operation of the traveling vehicle in accordance with information sent from the third communication device.

Control system and traveling vehicle

A tractor includes a controller configured to make a determination as to whether stopping control is necessary and to start the stopping control, based on a relation between a target bale size and a current bale size and a stopping distance corresponding to a vehicle speed and a surrounding environment.

Traveling vehicle and working vehicle

A traveling vehicle includes a controller to control a posture of a work machine via a connector. The controller observes whether a farm field surface on which the traveling vehicle travels and the work machine maintain a predetermined positional relationship therebetween, and controls the posture of the work machine when a positional relationship between the farm field surface and the work machine changes from the predetermined positional relationship, so that the positional relationship thus changed is reset to the predetermined positional relationship.

Traveling vehicle

An agricultural machine includes a baler controller configured or programmed to obtain an ejector inclination value from a positional relation between a tractor inclination sensor and a bale ejector of a baler, the ejector inclination value being a sensor value of the inclination sensor corresponding to the bale ejector, and to allow ejection of the bale when a size of the bale in the baler is larger than a first threshold value and the ejector inclination value is less than a second threshold value.

Agricultural machine

A controller for a baler, includes an ejecting position acquisition circuit, a prohibited position acquisition circuit, and a control circuit. The ejecting position acquisition circuit is configured to acquire an ejecting position at which an ejecting unit of the baler is configured to eject a bale of grass. The prohibited position acquisition circuit is configured to acquire a prohibited position. The control circuit is configured to control the ejecting unit to eject the bale at the ejecting position if the ejecting position is different from the prohibited position.
