<P>PROBLEM TO BE SOLVED: To provide a control mechanism of a HST transmission, controlling right and left HST transmissions so that right and left traveling devices are simultaneously driven or stopped. <P>SOLUTION: Control mechanisms for automatically controlling operating parts 9L, 9R for performing the shifting operation of HST transmissions by rocking are provided corresponding to the respective operating parts 9L, 9R so that in the neutral position of a shifting lever 13, the right and let HST transmissions respectively corresponding to the right and left traveling devices 2L, 2R are neutral. Rocking of both operating parts 9L, 9R is automatically controlled so that when the shifting lever 13 is located in a forward travel start position or a backward travel start position, the right and left traveling devices 2L, 2R are simultaneously driven to the forward side or the backward side. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
