To provide an agricultural work vehicle having travel control enabling the agricultural work vehicle to come close to an agricultural field border line such as a ridge while avoiding the contact with the border line.SOLUTION: The agricultural work vehicle comprises: a border line data management part 54 managing border line data showing a map position of a border line of an agricultural field; an own vehicle position calculation part 50 calculating a position of an own vehicle on the basis of positioning data from an own vehicle position detecting module; a traveling azimuth calculation part 57 calculating a travelling azimuth of a vehicle body from the own vehicle position; an apart distance calculation part 55 calculating a vertically apart distance to the border line from the vehicle body at the travelling azimuth as an apart distance on the basis of the travelling azimuth and the contour of a vehicle body; and a vehicle speed management part 513 managing vehicle speed in accordance with the apart distance.SELECTED DRAWING: Figure 5

    【課題】畦等の圃場の境界線との接触を回避しながらも、その境界線に接近することができる走行制御を有する農作業車の提供。【解決手段】農作業車は、圃場の境界線の地図位置を示す境界線データを管理する境界線データ管理部54と、自車位置検出モジュールからの測位データに基づいて自車位置を算出する自車位置算出部50と、自車位置から車体の走行方位を算出する走行方位算出部57と、走行方位と車体の外形とに基づいて走行方位での車体から境界線までの縦離間距離を離間距離として算出する離間距離算出部55と、離間距離に応じて車速を管理する車速管理部513とを備える。【選択図】図5
