ける走行操作装置。 A mobile agricultural machine equipped with a traveling transmission mechanism 3 consisting of a continuously variable transmission section 1 and a forward/reverse switching section 2, and driven by power transmission from the output side of the continuously variable transmission section 1,
An operating plate P that swings about a support shaft 6 by the operation of a speed change lever 5 installed on the control section 4 is mounted, and the support shaft 6 is equipped with an operating plate P for changing the speed of the continuously variable transmission section 1. The respective base sides of the driving speed change link 7 that controls the driving and the forward/reverse switching link 8 that switches the forward/reverse switching section 2 are loosely fitted through long holes 9 and attached to the sides of the actuating plate P. A cam groove 10 for increasing/decreasing speed change and a cam groove 11 for forward/reverse switching are respectively bored in the plate P.
The traveling speed change link 7 is provided in each of the cam grooves 10 and 11.
The pin shafts 12 and 13 protruding from the base of the forward/reverse switching link 8 are slidably fitted to the base side of the forward/reverse switching link 8, and by swinging the actuating plate P, the travel speed changing link 7 and the forward/reverse switching link 8 are slidably fitted together. The link 8 is simultaneously moved from an intermediate position between the zero speed range N1 and the neutral range N2, and the increase/decrease shift in the continuously variable transmission section 1 and the switching of the forward/reverse switching section 2 can be operated by the shift lever 5. A travel control device for a mobile agricultural machine characterized by the following features.
