PROBLEM TO BE SOLVED: To provide a sugar cane harvester capable of ensuring a sufficient lifting amount of a raising device and preventing interference with the ground or scaffolding.SOLUTION: A sugar cane harvester 1 includes: a base cutter 3 serving as a reaping device； a front conveyance device 4 and a rear conveyance device 5 serving as a conveyance device conveying a stem reaped by the base cutter 3 in a laterally fallen posture； and a chopping device 6 serving as a processing part cutting the stem conveyed by the conveyance device in a predetermined dimension. A crop divider 2 serving as a raising device is arranged so as to be lifted/lowered through a lifting/lowering link mechanism 12 in a front part of a machine body frame 30. The lifting/lowering link mechanism 12 comprises a front four-bar link 50 and a rear four-bar link 60. The rear four-bar link 60 is lifted/lowered by a hydraulic cylinder 70 serving as lifting/lowering drive means. The front four-bar link 50 is attached to the rear four-bar link 60 so as to be lifted/lowered within a predetermined angle restricted by an oscillation restriction part 72.SELECTED DRAWING: Figure 3【課題】引起し装置は十分な上昇量が確保でき、地面やアユミに干渉しないサトウキビ収穫機を提供しようとする。【解決手段】刈取装置となるベースカッター３と、ベースカッター３によって刈り取った茎幹を横倒し姿勢で搬送する搬送装置となる前搬送装置４と後搬送装置５と、搬送装置で搬送された茎幹を所定寸法で切断する処理部となるチョッピング装置６とを備えたサトウキビ収穫機１であって、機体フレーム３０の前部に昇降リンク機構１２を介して引起し装置となるクロップデバイダ２が昇降可能に配置され、該昇降リンク機構１２は、前四節リンク５０と後四節リンク６０より構成され、後四節リンク６０は昇降駆動手段となる油圧シリンダ７０により昇降され、前四節リンク５０は揺動規制部７２で規制される所定角度内で後四節リンク６０に対して昇降自在に取り付けられる。【選択図】図３
