The invention relates to an arrangement for controlling deflection motions of a crawler track driven undercarriage, wherein an undercarriage (2), being meant for a working machine (1) applicable especially for off-road use, comprises on sides thereof stiff crawler track bodies (3) in longitudinal direction (s) of the undercarriage, wherein ends of the crawler track bodies are provided with idle wheels (4) for crawler track use (T). The crawler track bodies (3) are coupled with a center frame (R) of the undercarriage turnably in a vertical plane along the longitudinal direction (s) of the undercarriage by rotating joints (N) between the center frame and the crawler track bodies, wherein at joint points connecting the center frame (R) of the undercarriage and the crawler track bodies (3) is arranged a coupling arrangement (5) for adjusting strain. The arrangement in the undercarriage comprises a pressure medium operated, advantageously hydraulic, adjustment arrangement, whereby a movement in direction of height (h) of the crawler track body on the one side causes a movement of a corresponding magnitude in opposite direction of the crawler track body on the opposite side by using one or more hydraulic cylinders connecting the crawler track bodies (3) and the center frame (R) at least in a power transmitting manner. The hydraulic cylinders belonging to the arrangement that control rolling motion of the crawler track bodies (3) are coupled on opposite sides of the undercarriage by first ends thereof with the first coupling parts of the coupling arrangement (5) and by second ends thereof with second coupling parts of the coupling arrangement (5).
