A high-maneuverability variable-steering tractor comprising a front part (11) which provides a front frame (14) and a rear part (12) which provides a rear frame (18), articulated to each other in a pivot (13), the front frame (14) being associated with an engine (15) and a front axle (16) bearing two front wheels (17), steering with respect to the same, and the rear frame (18) providing a rear axle (18) bearing rear wheels (20), wherein at least a first double-acting hydraulic cylinder (21 or 22) is provided in correspondence with the front axle (16), which defines a control for the front wheels (17); a hydraulic pump (38) and a power steering (42) connected to a steering wheel (51) of the tractor also being provided, wherein at least a second double-acting hydraulic cylinder (40 or 41) is provided between the front frame (14) and the rear frame (18) at the pivot (13) for rotating the front frame (14) with respect to the rear frame (18), an electronic control unit (49) being provided, and also an oil-flow distribution hydraulic block (50) coming from the pump (38) operatively connected to sensors (37, 39) for aligning the front frame (11) and the rear frame (12), and a selector (52) being provided which can be actuated by the user for selecting an operating position, which makes it possible to act on the front steering, on the central steering or on both in order to have the type of steering deemed necessary and selected.
