COMBINE-HARVESTER

To provide a combine-harvester which can efficiently move to a reaping start position of the next reaping work row regardless of the operator's maneuvering skill.SOLUTION: A combine-harvester in which a reaping device (3) is installed on the front side of a machine body that is driven by a travel device (2), and a sorting device (4) is installed to separate grains from grain culms reaped by the reaping device (3), includes: a position information reception device (51) which receives position information of the machine body; a position information acquisition member (52) which records the position information received from the position information reception device (51); and a travel calculation device (50) which calculates a first straight travel reference line (BG1) that becomes a reference of straight travel from the recorded position information. The combine-harvester also includes a process termination detection unit which detects the termination of a reaping work process. When the process termination detection unit detects the termination of the process, the combine-harvester calculates a second straight travel reference line (BG2) crossing the first straight travel reference line (BG1).SELECTED DRAWING: Figure 12 【課題】作業者の操縦技能に左右されず、次の刈取作業条の刈取開始位置に能率的に移動することが可能なコンバインを提供する。【解決手段】走行装置（２）で走行する機体の前側に刈取装置（３）を設け、該刈取装置（３）で刈り取った穀稈から穀粒を分離する選別装置（４）を設けたコンバインにおいて、機体の位置情報を受信する位置情報受信装置（５１）を設け、該位置情報受信装置（５１）から受信した位置情報を記録させる位置情報取得部材（５２）を設け、記録した位置情報から直進走行の基準となる第１直進基準線（ＢＧ１）を算出する走行演算装置（５０）を備え、刈取作業行程の終了を検出する行程終了検出部を備え、前記行程終了検出部が行程の終了を検出すると、前記第１直進基準線（ＢＧ１）に交差する第２直進基準線（ＢＧ２）を算出する。【選択図】図１２
