摘要： PROBLEM TO BE SOLVED: To make it possible to smoothly carry out a transmission guide for a long period of time and obtain the number of engine revolutions corresponding to the operational position of a transmission lever, by stably maintaining the interlocking relationship between the transmission lever and a speed governing mechanism. SOLUTION: The working machine is provided with the transmission lever 11 which reversely executes a forward acceleration operation and a rearward acceleration operation of a non-stage transmission for travelling, as the transmission lever 11 oscillates from a neutral position around a first shaft core to one side or the other side. A forward and rearward switching route C allowing the transmission lever 11 to move between the forward operation route and the rearward operation route is formed as the transmission lever 11 oscillates around a second shaft core being in a neutral position of the transmission lever 11. The engine speed governing mechanism is interlocked with the transmission lever 11 to be in the state of high speed revolution when the transmission lever 11 is in a high speed position. Arrangement is made so that the transmission lever 11 is made to come in contact with the guide surface 24 which slidably guides along the forward operation route by engaging the transmission lever 11 from the direction orthogonal to the guide surface 24.

摘要： PROBLEM TO BE SOLVED: To provide a sulky type rice paddy working machine capable of making a pedal operation simply and easily. SOLUTION: In this rice paddy working machine, a main hydraulic drive transmission composed of a hydraulic non-stage transmission gear that can revolve in the right and reverse directions is directly transmitted to front wheels and rear wheels after its transmission output is transmitted to a gear-type sub-transmission mechanism without interposition of a main clutch. The machine is equipped with a compulsory reconversion mechanism 120 which reconverts a main transmission lever 46 to a neutral position N, interlocked with a knocking-over operation of a pedal 25 which operates a brake for stopping the machine itself. It is also equipped with a compulsory neutrality reconversion mechanism 20 that forcibly reconverts a main transmission lever 46 at an F- position of a forward movement or an R-position of a reverse movement of the machine to a neutral N position interlocked with a knock-over operation of a pedal 5 to operate a brake for stopping the machine.
