Abstract: A speed change display control device includes a display screen generator generating a first display screen and a second display screen. The first display screen includes: an auxiliary speed change stage display area displaying auxiliary speed change stages; a main speed change stage display area displaying main speed change stages assigned to the auxiliary speed change stages; and an engaged speed change stage display area displaying engaged speed change stages. The second display screen includes: the auxiliary speed change stage display area; the main speed change stage display area; a lower limit selection area where the speed change stage defining a lower limit of a vehicle speed change ratio is selected; an upper limit selection area where the speed change stage defining an upper limit of the vehicle speed change ratio is selected; and a selected speed change stage display area displaying the currently selected upper limit and lower limit speed change stages.

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.
