PROBLEM TO BE SOLVED: To improve ill-drained paddy field travelling performance of a travelling machine body with a simple configuration.SOLUTION: A work vehicle includes travelling wheels 4 which support a travelling machine body and basket wheels 100 which are detachably attached to the travelling wheels 4. Each of the basket wheels 100 includes an annular rim part 102 and a plurality of basket wheel lugs 105 provided on the rim part 102 at appropriate intervals in a circumferential direction of the rim part 102. Each basket wheel lug 105 is tilted in a side view so that an outer peripheral side end part 105a side is positioned closer to an upstream side in a rotation direction in the advance of the travelling machine body than an inner peripheral side end part 105c side . The outer peripheral side end part 105a of each basket wheel lug 105 is bent towards a rotation center side of the rim part 102.SELECTED DRAWING: Figure 6【課題】簡単な構成で走行機体の湿田走破性を向上させるようにする。【解決手段】作業車両は、走行機体を支持する走行車輪４と、走行車輪４に着脱自在に取り付けられるカゴ車輪１００を備える。カゴ車輪１００は、環状のリム部１０２と、リム部１０２の周方向に沿って適宜間隔でリム部１０２に設けられた複数のカゴ車輪ラグ１０５を備える。カゴ車輪ラグ１０５は、側面視で、外周側端部１０５ａ側が内周側端部１０５ｃ側よりも走行機体の前進時の回転方向上流側に位置するように傾斜している。カゴ車輪ラグ１０５の外周側端部１０５ａがリム部１０２の回転中心側へ曲がっている。【選択図】図６
