The vehicle (1) has two front driving and steering wheels (4) each actuated by a hydraulic motor (8) arranged in said wheel. A hydraulic circuit (10) carries a fluid under pressure to actuate the hydraulic motors (8). Said hydraulic circuit comprises a static part mounted on the vehicle frame (2) and hydraulically connected to each of said hydraulic motors (8) by means of two main lines (31, 32). Each main line comprises a first rigid pipe (35) extending from the hydraulic distribution block, a second rigid pipe (36) extending from the corresponding hydraulic motor, and a flexible hose (37) connecting the free end portions (41, 46) of the first and second rigid pipes (35, 36). The free end portions (41, 46) of the first and second rigid pipes (35, 36) of a same main line (31, 32), and therefore the flexible hose (37), are located substantially in a same horizontal operating plane (P1, P2). |
