して回動不能となる欠点もあつた。 Conventional steering control devices for riding-type mobile agricultural machinery such as riding-type rice transplanters and tractors generally have left and right steering control arms RO and RO derived from the transmission case in opposite directions, as shown in Figure 3. and each of these steering operation arms,
The left and right steering operation pedals C and C' connected to B' are arranged side by side on either the left or right side of the aircraft body. Therefore, the steering operation pedals A and C' side arm lo' and the corresponding pedal c' are located in close proximity and their connection structure is easy, but the arm lo and the corresponding pedal ha on the opposite side are separated from each other on the left and right opposite sides. Due to their location, their connection structure is inevitably complicated and requires a large number of parts. That is, to explain this in detail, a long pipe shaft N' and a shaft extending in the width direction of the fuselage are provided on a frame fixed on the transmission case, and the shaft is rotatably inserted through and supported by the pipe shaft N'. While fixing the pedal to the shaft, a connecting arm is fixed to the other side protruding end of the shaft, and the steering operation arm is connected to the connecting arm via a rod, and the pedal is further attached to the protruding end of the shaft on the pedal side. In this case, it was necessary to use a complicated connection structure in which the pedal shaft was rotatably supported, and there was also the disadvantage that rust formed on the rotating part of the shaft, making it impossible to rotate it.

とするものである。 In order to simplify the conventional complicated steering operation device structure as described above, the present invention is aimed at simplifying the conventional complicated steering operation device structure in a riding type mobile agricultural machine in which both left and right steering operation pedals are arranged in parallel on either the left or right side of the machine body. The fulcrum shafts of the left and right steering operation arms connected to the steering pedals are respectively disposed on opposite sides of the clutch shaft and diagonally across the central clutch gear,
By having the rotating tips of the left and right steering operation arms facing the same side of the aircraft and protruding in a substantially parallel manner with a step, each steering operation can be performed without changing the arrangement of the left and right steering operation pedals. The connection structure between the operation pedal and the steering operation arm corresponding to each pedal can be significantly simplified with a minimum number of parts, and it is also extremely easy to assemble and disassemble, and there is no rust on the sliding parts. It is an object of the present invention to provide a steering operation device for a riding-type mobile agricultural machine that can always perform steering operations reliably by minimizing the margin of error.

切断される。 In the configuration as described above, when turning left, when the left wheel steering operation pedal 5 is depressed to stop the left rear wheel 3, the left steering operation arm 13 rotates around the fulcrum shaft 15 via the connecting rod 19. The left steering operation arm 13 rotates in the direction of the arrow in FIG.
The fulcrum shaft 15 and shifter 17 which are integral with the fulcrum shaft 15 also rotate in the same direction, and the rotation of the shifter 17 moves the left wheel side clutch 11 in a direction away from the clutch gear 9 against the spring 12. Since the engagement with the clutch pawl 9' is released, the transmission of power to the left wheel 3 is cut off.

うことができる効果がある。 As described above, the present invention provides a riding type mobile agricultural machine in which both left and right steering operation pedals are arranged in parallel on either the left or right side of the machine body, and the left and right steering operation pedals are connected to the left and right steering pedals, respectively. The fulcrum shafts of the left and right steering operation arms are arranged on opposite sides of the clutch shaft and diagonally across the center clutch gear, and the rotating tips of the left and right steering operation arms are on the same side of the fuselage. Since they are made to protrude in a substantially parallel manner with a step, each steering operation pedal and the steering operation arm corresponding to each pedal can be rationally arranged without changing the conventional arrangement of the left and right steering operation pedals. This makes it possible to connect and configure the steering wheel very easily using a minimum number of parts, which not only greatly simplifies the steering operation mechanism, but also
It is extremely easy to assemble and disassemble, which reduces costs by reducing the number of parts.It also minimizes the possibility of rust forming on the sliding parts of the connecting parts, ensuring reliable operation at all times. This has the effect of allowing steering operations to be performed.
