PROBLEM TO BE SOLVED: To provide a field working machine having a canopy which is firmly supported by a traveling machine body and whose vertical height can be easily changed. SOLUTION: A traveling machine body C capable of traveling in a field, a working device W which is supported and connected to a rear portion of the traveling machine body C so as to be able to move up and down with respect to the field, and which is capable of working on the field, and a traveling machine body C. The riding section 25 provided on the traveling body C over the lateral width of the traveling body C, the front support portion 32 standing upright on the front portion of the traveling body C, the standing upright on the rear portion of the traveling body C, and the upper and lower ends of the upper end. The rear support parts 54A and 54B whose heights can be changed are connected to the upper part of the front support part 32 so as to be swingably connected, and the free end part can be vertically swung. A canopy 50 that is supported and placed on and supported by the rear support portions 54A and 54B and that covers the riding portion 25 from above is provided.
