Abstract
To provide a travel control device for a working vehicle, including a speed change lever that is applicable even when a transmission in which speed stages are set to be larger by one stage is applied, the travel control device comprises a switching device () that switches speed changed by a transmission () either manually or automatically, a speed stage selecting device () that selects a speed stage out of a plurality of speed stages of the transmission (), and a first speed selecting device () that changes the speed stage manually down to a first speed separately from the speed stage selecting device (), regardless of a switching state of the switching device (), wherein the speed stage selecting device () selects the speed stages including a second speed or more but excluding the first speed, and a control device () is further provided, which controls the transmission () based on instructions sent from the switching device (), the speed stage selecting device (), and the first speed selecting device ().
