A chassis for a utility vehicle, especially for agricultural and forestry purposes, comprises a front frame (1) and a rear frame (2) connected thereto via an articulated joint (3) with a vertical pivot axis (5), Two mutually independently raisable and lowerable wheel units (6, 9, 10, 11; 14, 17, 18, 19, 22) are fitted at the sides of the front and rear frames. Substantially in the middle of the front and rear frames there is a bearer unit (25, 41) comprising a bearer component (28-36) and a raising device (26, 38) by means of which the bearing component can be raised and lowered. Here the bearing components have a cleated (36) endless band rolling on the ground (33) with the bearing component in the lowered position and the raising devices are designed in such a way that they are capable together of bearing at least half the total weight of the vehicle.
