【0037】 本発明によると、検出部が前の走行装置の向きと後の走行装置の向きとを検出する。そして、報知部が、検出部の検出結果に基づいて、中立の向きであるべき走行装置に中立ずれ状態が発生したことを報知する。このことから、オペレータ等が中立ずれ状態の発生に気付かないまま作業を継続する虞が回避される。これにより、中立の向きであるべき走行装置に中立ずれ状態が発生したことを、オペレータ等が容易に認識可能な作業車が実現される。また、本構成によって、非操向状態に設定された走行装置の向きをオペレータ等が中立の向きに戻す作業を行う際に、オペレータ等は操向操作具の操作方向を把握でき、操作が容易になる。

Abstract

To provide a work vehicle allowing an operator or the like to readily recognize occurrence of a neutrality deviation state in a travel apparatus that should head for a neutral orientation.SOLUTION: A work vehicle includes: a body; a preceding travel apparatus that is steerable; a succeeding travel apparatus that is steerable; a steering controller that can steer or control the preceding travel apparatus and the succeeding travel apparatus, and has plural steering modes which are different from one another in a steering control form; a detection unit that detects an orientation of the preceding travel apparatus and an orientation of the succeeding travel apparatus; and a notification unit. The plural steering modes include a steering mode in which one of the preceding travel apparatus and the succeeding travel apparatus is set to a steerable state and the other one of the preceding travel apparatus and the succeeding travel apparatus is set to a non-steering state. The notification unit makes a notification in response to occurrence of a neutrality deviation state in which the orientation of the travel apparatus set to the non-steering state is deviated by a predesignated threshold or more from a neutral orientation, on the basis of a result of detection by the detection unit.SELECTED DRAWING: Figure 8
