摘要： 스핀턴이 불필요한 작업에서의 작업능률의 향상 및 습답작업에서의 주행성능의 향상 등을 꾀한다.
주행변속레버(73)의 조작에 의해 주행속도를 무단경로 변경가능한 변속부재(25)를 통해 좌우주행크롤러(2)에 구동력을 전달하는 동시에, 조향핸들(19)에 의해 조향부재(28)를 조작해서 좌우주행크롤러(2)의 구동속도의 차를 무단경로 변화시키는 이동농기 등의 작업차에 있어서, 주행변속레버(73) 조작량에 의해 결정되는 차속을 조향핸들(19)조작량에 비례시켜 감속시키는 동시에, 조향핸들(19)조작량에 대한 차속의 감속비를 변경가능하게 한 것을 특징으로 한다.

摘要： In an operation mechanism of an HST system transmission apparatus of the type in which an HST system non-stage transmission mechanism for driving and an HST system non-stage transmission mechanism for turning are disposed, the HST system non-stage transmission mechanism is operated by a transmission lever and the HST system non-stage transmission mechanism for turning is operated by a round operation wheel, a steering mechanism can make a turning operation matching turn feeling desired by an operator in turning at both low and high speeds. Namely a in the operation of the HST system transmission apparatus wherein the HST system non-stage transmission mechanism (25) for driving is operated by a transmission lever (68) and the HST system non-stage transmission mechanism (28) for turning is operated by a round operation wheel (19), a speed ratio between right and left driving devices is changed in accordance with the operation turning angle of the round operation wheel (19). The turning radius is changed, even with the same operation turning angle of the round operation wheel (19), by the difference of the operation angle of the transmission lever (68).

CONSTITUTION: In an operation mechanism of an HST system transmission apparatus of the type in which an HST system non-stage transmission mechanism for driving and an HST system non-stage transmission mechanism for turning are disposed, the HST system non-stage transmission mechanism is operated by a transmission lever and the HST system non-stage transmission mechanism for turning is operated by a round operation wheel, a steering mechanism can make a turning operation matching turn feeling desired by an operator in turning at both low and high speeds. Namely a in the operation of the HST system transmission apparatus wherein the HST system non-stage transmission mechanism (25) for driving is operated by a transmission lever and the HST system non-stage transmission mechanism (28) for turning is operated by a round operation wheel (19), a speed ratio between right and left driving devices is changed in accordance with the operation turning angle of the round operation wheel (19). The turning radius is changed, even with the same operation turning angle of the round operation wheel (19), by the difference of the operation angle of the transmission lever.
