Problem to be solved: to provide a tilling work machine capable of suppressing deformation due to weight of the rear cover of the tilling portion.The tiller working machine comprises a tilling portion (3) and a tilling part (W) comprising a rear cover (4) which is leveled about its tilling width, and is capable of running in a leveling manner, and the rear cover (4) is rotated by its rear cover in the direction of the tilling width A shaft (4a) is supported by a shaft, and a plurality of mounting parts of a distributed arrangement (5)... Since the weight portion (6) of the horizontally long configuration is mounted in the direction of the tilling width, the rear cover (4) is in the length (weight) weight portion (6) ofTherefore, both the flat load and the rigidity increase, so that the deformation of the rear cover 4 can be suppressed by the increase in the load due to the mounting of the weight portion 6.Diagram【課題】耕耘部のリヤカバーのウェイトによる変形を抑えることができる耕耘作業機を提供する。【解決手段】耕耘作業機は、回転耕耘爪(3)と、その耕耘幅について均平するリヤカバー(4)とからなる耕耘部(W)を備えて均平整地走行可能に構成され、前記リヤカバー(4)は、その前端を前記耕耘幅方向のリヤカバー回動軸(4a)によって軸支するとともに、分散配置の複数の取付部(5…)を備えて横長構成のウェイト部(6)を前記耕耘幅方向に亘って取付けたことから、リヤカバー(4)は、横長形状のウェイト部(6)によって均平荷重と剛性が共に増加することから、ウェイト部(6)の取り付けによる荷重の増加によっても、リヤカバー(4)の変形の抑制を可能とするものである。【選択図】図2
