In order to allow the tractor to work at the maximum steering angle without the mudguard (2) interfering with the other parts of the machine, the support (1) comprises a first element (7) which can be fixed to the axle (5) of the vehicle and a second element (8) which can be fixed to the mudguard (2), said two elements are connected by a third rotating element (9) and by a preloaded spring (11) . The third rotating element (9) has the rotation axis (10) which coincides with the steering axis (6) of the hub (4) . The third element (9) is provided with a second abutment element (13) suitable to oppose the axle (5) when the current steering angle coincides with the maximum steering angle, the element (13) stops the rotation of the mudguard (2) with respect to the axle (5) i.e. the progressive divergence of the rolling plane (28) of the steering wheel (3) with respect to the centre axis (29) of the mudguard (2).
