The present invention aims to provide a work machine for easy maintenance of a cooling fan placed in between an engine and a radiator. wherein: there are an outbound pipe (52) and a return pipe (53) having flexibility and shape maintenance and placed to access an intercooler (30) and an engine (14) and to penetrate a mounting frame (28) in the direction of inside and outside of the gas the mounting frame (28) has a main frame unit (38) for supporting the intercooler (30) and a supporting unit (39) for supporting the outbound pipe (52) and the return pipe (53) the mounting frame (28) is made to be able to fluctuate around X, which is the axis core of rotation the supporting unit (39) is able to be changed into a supporting status for being supported on the main frame unit (38) and a supporting release status for the supporting status to be released. In addition, the present invention can conduct the assembly of a cutting returning unit and a threshing unit and to prevent sedimentation of straw fragments in the bottom space of an entrance plate. The work machine of the present invention has: the entrance plate (1015) for guiding the cutting granary, which is cut and returned to the rear by the cutting returning unit, to a granary supply hole (1024) formed on the front side of the threshing unit (1004) a guide plate (1045) for guiding the straw fragments falling from a passing opening of the cutting returning unit and the entrance plate (1015) to the outside beyond the bottom space of the entrance plate (1015) and, a space filling member (1071) made from soft materials and installed in between the guiding plate (1045) and the entrance plate (1015).COPYRIGHT KIPO 2016본 발명은 엔진과 라디에이터 사이에 배치되는 냉각 팬의 유지 보수를 용이하게 행할 수 있는 작업기를 제공하기 위한 것으로, 인터쿨러(30)와 엔진(14)을 접속하고, 탑재 프레임(28)을 기체 내외 방향으로 관통하도록 배치되는 가요성 및 형상 유지성을 갖는 왕로관(52) 및 복로관(53)이 구비되고, 탑재 프레임(28)에, 인터쿨러(30)를 지지하는 본체부(38)와, 왕로관(52) 및 복로관(53)을 지지 가능한 지지부(39)가 구비되고, 탑재 프레임(28)이 회동 축심 X 주위로 요동 가능하게 구성되고, 지지부(39)가 본체부(38)에 지지되는
