Provided is a work vehicle capable of efficiently performing grass collecting work by decelerating a traveling machine body in a case where the size of a bale is large and a case where the pickup load of straw grass is large. The work vehicle includes a traveling machine body 1, a roll baler unit 2, a bale detection unit 31 configured to detect a size of the bale formed by the roll baler unit 2, a load detection unit 32 configured to detect a pickup load of straw grass in the roll baler unit 2, and a traveling control unit 17A capable of decelerating the traveling machine body 1 when a size of the bale is equal to or larger than a setting value B1 and when a pickup load is equal to or larger than a setting value L. A deceleration D2 is larger than a deceleration D1.

A work vehicle incudes a traveling mechanism driven by a rotational power from an engine and an implement for effecting a ground work by the rotational power of the engine. The work vehicle further includes a load ratio calculation section 53 for calculating an engine load ratio indicative of an engine load of the engine, a ground speed calculation section 51 for calculating a ground speed of the vehicle body with using satellite positioning data, a slip ratio calculation section 52 for calculating a slip ratio indicative of slippage of the traveling mechanism relative to a ground surface by using the ground speed, a traveling work control section 4 for creating an appropriate traveling work state by controlling a rotational speed of the engine and a posture of the implement, and a traveling work management section 50 for outputting a state changing command that commands a change of the traveling work state, based on the engine load ratio and the slip ratio.
