To provide a self-propelled work machine equipped with a discharge conveyor, which carries out strain adjustment of a belt body of the discharge conveyor by displacing a right side and a left side of a driven wheel in a manner preventing right and left displacements from being dispersed.
According to the structure of the self-propelled work machine, a strain adjusting means is comprised of a pair of adjusting nut bodies 20 connected to respective right and left side portions of the driven wheel 13, and a pair of screw shafts 21 onto which the adjusting nut bodies 20 are screwed to relatively move with respect to each other. Each screw shaft 21 of the strain adjusting means has a screw groove 21b formed at one end thereof. Further the strain adjusting means is comprised of displacement measuring nut bodies 22 screwed into the screw grooves 21b in synchronization with the respective adjusting nut bodies 20, and a pair of scale devices 23 for measuring displacements of the respective displacement measuring nut bodies 22.
