A wheel loader (1) has a tire (5). The wheel loader (1) includes a hydraulic pump (11), a hydraulic oil tank (7) disposed at a position higher than the hydraulic pump (11) and connected to the hydraulic pump (11), a check valve (12) disposed at a position lower than the hydraulic oil tank (7) and connected to the hydraulic oil tank (7), a filter (13) disposed at a position lower than an upper surface (US) of the tire (5) in a side view and connected to the check valve (12), and a pipe (14) extending to a first position (H1) lower than the check valve (12) and further extending from the first position (H1) to a second position (H2) as a higher position than the check value (12) is set as the second position (H2), and connected to the filter (13) at the second position (H2). Accordingly, it is possible to provide a work vehicle capable of inhibiting a hydraulic oil from spilling out in exchanging the filter (13).
