An isodiametric tractor with minimum maintenance comprising a chassis (50; 50', 50") carrying a front axle (52) and a rear axle (52') for pairs of front wheels (51) and rear wheels (51'), wherein two front wheels (51) are driving wheels and are actuated by a motor (71) with the interpositioning of a differential and wherein transmission means for transmitting motion from the motor (71) to the wheels (51) are entirely contained in the chassis, wherein each wheel (51) of the front axle (52) is also connected to the chassis (50; 50', 50") and/or to a differential casing by a respective articulated kinematic group, wherein said motor (71) is cantileverfixed to a front end of the chassis (50; 50', 50"), wherein each articulated kinematic group of each wheel (51) of the front axle is associated with a hydraulic cylinder (61, 62), associated by means of a pin (63, 64; 158) with a portion of the chassis (50; 50', 50") and at the other end, with a portion (56; 155) of the articulated kinematic group, wherein each hydraulic cylinder (61, 62) comprises two chambers having a variable volume, opposite with respect to an intermediate piston (69, 70), wherein an upper chamber of one cylinder (61) is connected (in 67) to an upper chamber of the other cylinder (62) and a lower chamber of one cylinder (61) is connected (in 68) to a lower chamber of the other cylinder (62).
