A movable fulcrum shaft (93) and a loading and shifting arm (94) (95) for connecting the base end to the fulcrum shaft (93) so as to swing freely in an inverted eight-height shape;
A shaft guide plate (97) for guiding the fulcrum shaft (93) in the front-rear direction along the guide groove (96); and a travel connecting the travel speed change lever (29) and the tip of the speed change arm (95). A wire (98), a loading wire (100) for connecting between a loading operation lever (99) provided near the speed change lever (29) and the loading arm (94), and the speed change lever (29). ) Is switched from the planting advance position to the reverse position, as shown by the imaginary line in FIG. 10, the traveling wire (98) is pulled, and only the transmission arm (95) is swung rearward about the fulcrum shaft (93). Then, the transmission arm base end surface (95) is
a) is brought into contact with the loading wire (1) when the loading operation lever (99) is switched from the reverse position to the loading speed.
00) to move the loading arm (94) rearward integrally with the fulcrum shaft (93) and the shifting arm (95), as shown in FIG. The wire (92) is pulled to control the engine (2) to decelerate at a very low speed, so that the operation can be performed at a very low speed when the vehicle such as a truck is loaded, regardless of the position of the accelerator lever.
