介在してあることを特徴とする歩行型農作業機。[Claims for Utility Model Registration] The output shaft 5 of the engine 3 and the input shaft 6 of the transmission case 2 are interlocked and connected by a double tension sub-transmission mechanism 7 capable of transmission of variable speeds in two high and low stages. PT that transmits power from shaft 6 to PTO shaft 8
A gear type PTO transmission mechanism 9 capable of shifting into two high and low speeds is provided in the O system, and the speed ratio between the high speed state and the low speed state in the auxiliary transmission mechanism 7, as well as the PTO
In a walk-behind agricultural working machine in which the speed ratio between the high speed state and the low speed state in the transmission mechanism 9 is set to be approximately equal, the auxiliary speed change lever 26 at hand and the speed change operation shaft 20 of the PTO transmission mechanism 9 are connected to each other. A mechanical linking means is used so that the PTO transmission mechanism 9 is switched to low speed in conjunction with the high speed switching of the auxiliary shift lever 26, and the PTO transmission mechanism 9 is switched to high speed in conjunction with the low speed switching of the auxiliary shift lever 26. A walking agricultural working machine characterized in that an elastic flexibility mechanism 44 is interposed in the linking means between the speed change operation shaft 20 of the PTO speed change mechanism 9 and the sub speed change lever 26.
