PROBLEM TO BE SOLVED: To provide a mobile farm working machine so designed as to reduce its traveling speed by the aid of a speed reducer depending on workload conditions and thereafter, shift the main speed change lever to lower speed side further depending on workload conditions so as to favorably enable vehicle speed control independently of the shift position of the main speed change lever. SOLUTION: This mobile farm working machine is so designed as to reduce the traveling speed by the aid of a speed reducer when workload exceeds a set level and engine revolutions comes blow a set value, and thereafter, when the workload is increased further and comes to a set value or greater, shift the main speed change lever to lower speed side; wherein it is preferably that, when workload is decreased, the vehicle traveling speed is increased by the above-reduced magnitude, and the main speed change lever is shifted by the aid of a neutral return mechanism. |
