PROBLEM TO BE SOLVED: To obtain a working machine which can allow a working device to swing on a swinging support shaft and can thereby hold the working device in a constant posture to well ensure a good working performance, even when the travel vehicle body is laterally swung due to the uneven surface of a field, by detachably attaching the working device to a hitch member attached by a specific method. SOLUTION: In this working machine, a working device is connected to the rear portion of a travel vehicle body B through a lifting mechanism D, and a vehicle body frame 2 is disposed between a pair of right and left crawler type travel members 1 in the travel vehicle body B. An operation seat 3, a motor portion 4 and a transmission 5 are arranged on the vehicle body frame 2, and the travel members 1 are interlocked and connected to the motor portion 4 through the transmission 5. Therein, a hitch member is axially rotatably attached to the lifting mechanism D through a swinging support shaft whose axis is directed in the longitudinal direction, and the working device is detachably attached to the hitch member.
