PROBLEM TO BE SOLVED: To provide a sugar cane harvester capable of avoiding damage caused by impact by lifting a raising device when a grass dividing device contacts an obstacle.SOLUTION: A sugar cane harvester 1 includes: a reaping device; conveyance devices 4, 5 conveying a stem reaped by a reaping device in a laterally fallen posture; and a chopping device 6 serving as a processing part cutting a stem conveyed by the conveyance devices 4, 5 in a predetermined dimension. A crop divider 2 serving as a raising device is arranged so as to be lifted/lowered in a front part of a machine body frame 30. A grass dividing tool 40 including a guide face lifted rearward is arranged in a front edge of the crop divider 2. The grass dividing tool 40 comprises a front side movable grass dividing part 42 and a fixed grass dividing part 41. The movable grass dividing part 42 rotates so as to lower its front edge with a rotation shaft 43 as a center.SELECTED DRAWING: Figure 7【課題】分草装置が障害物に当接したときに、引起し装置が上昇し、衝撃による破損を回避できる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、刈取装置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4・5と、搬送装置4・5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の前部には、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、クロップデバイダ2の前端に後ろ上がりのガイド面を有する分草具40が設けられ、該分草具40は、前側の可動分草部42と固定分草部41からなり、可動分草部42は、回転軸43を中心に前端が下がるように回転する構成される。【選択図】図7
