The invention relates to a hydrostatic traveling mechanism (4) that comprises a closed hydraulic circuit (6) in which a first hydraulic pump (4) with a first hydraulic engine (12) is linked with a flow pipe (7) and a return pipe (8). Said hydraulic engine (12) drives the vehicle wheels (14, 15, 18, 19) of two first vehicle axles (17, 20). According to the invention, an additional open hydraulic circuit (9) is used in which a second hydraulic engine (22) and a third hydraulic engine (24) are linked with a second hydraulic pump (5) via a supply pipe (11) and a control valve (21). Said second hydraulic engine (22) and said third hydraulic engine (24) drive the vehicle wheels (23, 25) of a second vehicle axle (36).
