A harvester capable of autonomous travel in a field includes: a harvesting unit that harvests a crop from the field; a conveyance device that conveys, toward the rear of a harvester body, a whole culm of the harvested crop harvested by the harvesting unit; a detection sensor that detects a drive speed of the conveyance device; and a clog determining unit that determines a clog of the harvested crop in the conveyance device on the basis of the drive speed. The clog determining unit outputs a vehicle stop command that stops the harvester body when the drive speed becomes lower than a pre-set first threshold during the autonomous travel.

A field map generating system includes: a crop data obtaining unit that obtains crop data over time; a position information obtaining unit that obtains position information, indicating a harvesting position of the crop, over time; polygon constructing units that construct a polygon on the basis of a work width and speed of a harvester, for each piece of crop data obtained by the crop data obtaining unit; data assigning units that assign crop data or crop information based on the crop data to the constructed polygons; a position information assigning unit that assigns position information to the constructed polygons; and field map generating units that generate a field polygon map, which is an aggregate of the polygons, by aggregating the polygons.

The present disclosure includes a travel operation unit that is configured to be manually operated and includes a mode operation tool for switching between automatic driving and manual driving, a manual travel control unit that includes a manual travel mode in which manual driving is performed based an operation signal received from the travel operation unit, and an automatic travel control unit that includes an automatic travel mode in which automatic driving is performed, a temporary stop mode in which a vehicle body is temporarily stopped during automatic driving for transitioning from the automatic travel mode to the manual travel mode, and a check mode in which whether a state of the travel operation unit satisfies a manual driving transition condition required for starting manual driving is checked in transition from the temporary stop mode to the manual travel mode.

A combine harvester includes a conveyance mechanism for conveying grains obtained by a thresher for threshing grain culms reaped from a field to a grain tank, a measurer () for measuring the amount of grain conveyed to the grain tank as a conveyed yield, a yield assignment calculator () for calculating a minimal section yield, which is a yield per minimal section, by assigning the conveyed yield to a minimal section in the field, a grain conveyance state detector () for detecting a grain conveyance state of the conveyance mechanism (), a yield corrector () for correcting the minimal section yield in accordance with the grain conveyance state, and a yield distribution data generator () for generating yield distribution data that represents a yield distribution in the field, based on the minimal section yield.

An agricultural work management system includes: a data input unit configured to receive, from an agricultural crop harvester, harvesting position data indicating a harvesting work position as agricultural land information, harvest amount data indicating a harvest amount of the agricultural crop harvested in the agricultural land, and quality data indicating the quality thereof as agricultural crop information; a database server configured to store the agricultural land information and the agricultural crop information such that they can be associated with each other; an agricultural work evaluation unit configured to perform agricultural work evaluation on the agricultural land based on the agricultural land information and the agricultural crop information; and a data output unit configured to send out the agricultural work evaluation data generated by the agricultural work evaluation unit.
