PROBLEM TO BE SOLVED: To prevent an auxiliary transmission lever for transmitting into a very low speed from being unreasonably operated excepting for balk climbing or loading on/unloading to/from a truck, prevent a work machinery in a very low speed state for a long time, and prevent a transmission system from damaging and wearing. SOLUTION: In this four-wheel drive type farm machinery, a main transmission lever is arranged in the vicinity of a steering handle so as to be easily operated and the auxiliary transmission lever 43 is arranged far from the steering handle so as not to be easily operated. The machinery comprises a control means for returning a throttle for controlling an engine speed high and low into an idling position and restricting a move to the high speed side when the auxiliary transmission lever 43 is switched into the very low speed side.
