  • Publication number: 20170355372
    Abstract: Work vehicle having a coupling member which is switchable between a coupled state where left/right brake operation tools are integrally coupled and a released state releasing the coupling. A coupled state detector is utilized. A controller controls a traveling state and is switchable between a first or normal mode and a second or vehicle speed suppression mode. The second or vehicle speed suppression mode can be switched back to the first or normal mode when the coupled state is detected and a predetermined releasing operation is performed.

  • Patent number: 9283951
    Abstract: A speed change system for work vehicle having a continuously variable transmission device selects a first change gear ratio which is set larger than a smallest change gear ratio, when an engine rotational speed is a first set rotational speed which is set equal or close to an idling rotational speed of an engine; retains the change gear ratio of the continuously variable transmission device at the smallest change gear ratio, when the engine rotational speed is equal to or above a second set rotational speed set on a high-speed side relative to the first set rotational speed; and makes the change gear ratio of the continuously variable transmission device larger between the first change gear ratio and the smallest change gear ratio, as the engine rotational speed at that moment becomes lower, when the engine rotational speed is between the first and second set rotational speeds.
