To realize a crawler tractor that eliminates the need to additionally dispose a new hydraulic oil tank and has a machine-body layout substantially common with other types of tractors such as a wheel tractor.SOLUTION: In a crawler tractor comprising a pair of crawler type travel devices, right and left, a hydraulic piping device circulating by connecting a mission case provided in a rear part of a machine body and a swivel mission case provided in a front part of the machine body. In addition, an intermediate part, in forward and backward directions of the machine body, of the hydraulic piping device is used as a tank part formed from a pipe larger in diameter than a front piping part and a rear piping part. Hydraulic oil is stored in this tank part.SELECTED DRAWING: Figure 4

    【課題】新たに作動油タンクを追加配置する必要がなく、ホイルトラクタ等の他種類のトラクタと略共通の機体レイアウトを有するクローラトラクタを実現する。【解決手段】左右一対のクローラ式走行装置を備えるクローラトラクタであって、機体後部に設けたミッションケースと機体前部に設けた旋回用ミッションケースとを連結して循環する油圧配管装置を機体前後方向に沿って設けるとともに、前記油圧配管装置の機体前後方向中間部を、前側配管部及び後側配管部よりも大径のパイプによって構成されたタンク部とし、当該タンク部に作動油を貯留する構成とした。【選択図】図4
