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 work device W capable of working on the field, a riding section 25 provided on the traveling machine body C over the lateral width of the traveling machine body C, and a traveling machine body C. The first support portions 32 and 33 that are erected in one of the regions on one end side, the second support portions 42 that are erected in the region on the other end side of the traveling machine body C, and the first support portion 33. The satellite positioning unit 34 capable of detecting the position of the traveling body C using the navigation satellite, and the first supporting portion 33 swingably and the second supporting portion 42 support the riding portion 25 upward. The canopy 40 is covered with the canopy 40, and the vertical lifting mechanism 5 is provided at the upper end of the second support portion 42 and can lift the canopy 40 up and down.
