Abstract

To suppress a driver's confusion due to mismatching of an actual operation position of a main shift lever during constant speed traveling and a shift condition.SOLUTION: A work vehicle is equipped with a main transmission device, a main shift lever, a lever position detection sensor, a lever position memory switch, and a control portion. The main transmission device changes machine body traveling speed. The main shift lever is operated from a neutral position to a speed increasing side and a speed decreasing side, and is energized to a neutral position side. The lever position detection sensor detects an operation position of the main shift lever. The lever position memory switch is operated so as to memorize the operation position of the main shift lever. The control portion outputs a transmission instruction value corresponding to the operation position of the main shift lever to the main transmission device. The control portion memorizes the operation position of the main shift lever during the operation of the lever position memory switch, and if memorizing the operation position of the main shift lever, outputs the transmission instruction value corresponding to the memorized operation position, even if the main shift lever moves from the memorized operation position to the neutral position side.SELECTED DRAWING: Figure 3
