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【課題】作業車両の振動をより確実に抑制することができるようにする。【解決手段】作業車両において、電子制御によってエンジン回転数が変更されるエンジン１４と、電子制御によって走行用の動力を変速する走行用変速装置３０と、車体の振動を検出する振動センサ４９と、振動センサ４９の検出値が閾値以上のときに車体の振動を低下させる振動抑制制御を行う振動抑制制御部２２Ｈとを備え、振動抑制制御部２２Ｈは、振動抑制制御で実行する複数の振動抑制処理として、少なくとも、エンジン回転数を変更する回転数変更処理と、走行用の動力を変速する走行動力変速処理とを有し、振動抑制制御においては、複数の振動抑制処理のうちのいずれかの振動抑制処理を実行し、その実行後も振動センサ４９の検出値が閾値以上のときは、複数の振動抑制処理のうちの未実行のいずれかの振動抑制処理を実行する制御作動を繰り返す。【選択図】図３
