PROBLEM TO BE SOLVED: To prevent the occurrence of such an inconvenience as damage to a working vehicle during an operation where the working vehicle is forcibly lowered to a height position for being replenished with a feed material.SOLUTION: The working vehicle includes: a working device, vertically movably mounted on the back of a travelling vehicle, for supplying the feed material to a field and a controller for carrying out, upon detection of a request from the working device for replenishment of the feed material, a lift control for replenishment to automatically lift the working device from a working height position to a predetermined height position for replenishment of the feed material. In a feed material replenishment structure for the working vehicle, the controller is not allowed to carry out the lift control for replenishment when detecting the fact that the working device is in contact with the ground, and the working device requests replenishment of the feed material while being at a position higher than a height position for replenishment of the feed material.COPYRIGHT: (C)2013,JPO&INPIT【課題】作業装置の供給物補給高さ位置への無理な下降操作で作業装置が損傷するなどの不都合の発生を阻止する。【解決手段】走行車体の後部に供給物を圃場に供給する作業装置を昇降可能に装備し、作業装置への供給物の補給を要する状態を検知した場合に、作業装置を作業高さ位置から予め設定した供給物補給高さ位置まで自動昇降させる補給用昇降制御を実行する制御手段を備えた作業車の供給物補給構造において、作業装置の接地を検知し、かつ、作業装置の高さ位置が供給物補給高さ位置よりも高いことを検知した状態で、作業装置への供給物の補給を要する状態を検知した場合には、制御手段が補給用昇降制御を実行しないように構成してある。【選択図】図15
