A crawler-tracked vehicle with a variable track width can be used as a construction vehicle and/or as a vehicle for agricultural purposes. The vehicle includes an undervehicle with a vehicle frame, on which is provided on each of the two sides a chassis with a chassis carrier respectively for carrying at least one driving wheel and one deflecting wheel and supporting wheels for the guidance of crawler tracks. At least one of the two chassis carriers (10, 11) can be fastened releasably to the vehicle frame (7) at a different distance transversely to the undervehicle (6) with carrying elements (24, 25) arranged laterally at the front and rear and with receiving and supporting elements (26, 27) and with holding and releasing elements (28).
