Agriculture ground work vehicle monitoring system

An agricultural machine includes a swath information acquiring module, a first determining module to determine a traveling path of an automatic operation based on a position of a swath, a setting module to set a work continuation width based on the traveling path, a second determining module to determine, when there is a manual operation by a worker during the automatic operation, whether the agricultural machine during the manual operation is within the work continuation width, and an executing module to execute the automatic operation. The executing module restores the agricultural machine to the traveling path after a termination of the manual operation and continues the automatic operation when the agricultural machine is within the work continuation width, and cancels the automatic operation when the agricultural machine is determined to be not within the work continuation width.

Agricultural machine

Provided is a traveling assisting device for a work vehicle which makes it easy to avoid local compaction of the soil. There is provided a route determination section that determines a target traveling route based on a ground-contact expected area which is an area where the traveling device is expected to contact the ground surface in the field.

Traveling assisting device for work vehicle and the work vehicle

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.
