To more surely suppress vibration of a work vehicle.SOLUTION: A work vehicle includes: an engine 14 in which engine speed is changed by electronic control; a speed change device 30 for travel which changes speed of power for travel by electronic control; a vibration sensor 49 which detects vibration of a vehicle body; and a vibration suppression control section 22H which performs vibration suppression control to lower vibration of a vehicle body when a detection value of the vibration sensor 49 is a threshold or more. The vibration suppression control section 22H has at least a rotation number changing processing for changing the engine speed and travel power speed change processing for changing speed of power for travel as a plurality of kinds of vibration suppression processing to be executed in the vibration suppression control. In the vibration suppression control, any one vibration suppression processing of the plurality of kinds of vibration suppression processing is executed. When a detection value of the vibration sensor 49 is the threshold or more after the execution, a control operation for executing any one vibration suppression processing which is not executed of the plurality of kinds of vibration suppression processing is repeated.SELECTED DRAWING: Figure 3
