Abstract

A running vehicle of the present invention is provided with a static fluid-pressure stepless speed change device (4) for changing speed of running vehicle; an pars intermedia of speed change operating arm (43) locating on a rotor axis (4a) of the static fluid-pressure stepless speed change device for changing the output of the static fluid-pressure stepless speed change device as well as running speed; a speed change handle (40) for implementing speed change operation from a neutralism position where the output of the static fluid-pressure stepless speed change device is zero; an operation synergism motion mechanism (44, 45, 47a, 48) for transmitting the operation of the speed change handle to the speed change operating arm; a braking operation tool (41) for driving the output of the static fluid-pressure stepless speed change device be zero and stopping running; a stop linkage mechanism (41a, 41b, 60, 61, 62, 64) for transmitting the operation of the braking operation tool to the speed change operating arm, one side of the speed change operating arm is connected with the operation synergism motion mechanism based on a rotor, the other side is connected with the stop linkage mechanism.

Description

technical field [0001] The present invention relates to traveling vehicles such as tractors used in manned rice transplanters, manned vegetable transplanters, manned lawnmowers and the like equipped with various seedling planting devices. Background technique [0002] Conventionally, there is known a manned type seedling planting machine provided with a mechanical linkage mechanism in which a shift lever returns to a neutral position when the brake pedal is depressed (Patent Document 1: JP 2003-333907 A). [0003] The brake pedal of the manned type seedling planter described in Patent Document 1 and the above-mentioned mechanical linkage mechanism of the shift handle are complicated in structure due to packing complicated parts in a narrow space. Contents of the invention [0004] It is an object of the present invention to provide a traveling vehicle in which the mechanical interlocking mechanism of the brake pedal and the shift lever can be made into a simple structure, ...
