PROBLEM TO BE SOLVED: To provide a work vehicle which lifts/lowers a rotary tiller by an auto lever in a state in which a position lever is operated to a lowering side.SOLUTION: The work machine includes a lifting/lowering control device 50 including a position lever 41 lifting/lowering lift arms 7, 7 by switching a lifting/lowering control valve 51; an auto lever 42 lifting/lowering a rear cover 36 thereby setting/adjusting a target tillage depth in automatic tillage depth control in a state in which the position lever 41 is operated to the lowest position; a first link mechanism 52 connected from the position lever 41 to a spool 51a adjusting an opening degree of the lifting/lowering control valve 51; and a second link mechanism 53 connected from the auto lever 42 to the spool 51a. In a state in which the position lever 41 is operated to a lowering side by a predetermined amount or more, the auto lever 42 coordinates also with the first link mechanism 52.SELECTED DRAWING: Figure 6 |
