The invention discloses a land leveler swing front axle steering mechanism, and relates to the field of machines. The land leveler swing front axle steering mechanism comprises a left steering joint and a right steering joint which is each provided with a steering shaft, a lower rotary arm plate and an upper rotary arm plate; each lower rotary arm plate is connected with the corresponding upper rotary arm plate above the lower rotary arm plate through a vertical supporting plate and a transverse supporting plate, connecting holes are formed in the lower rotary arm plate and the upper rotary arm plate, and a limiting plate is arranged at the end, opposite to the connecting hole, of each upper rotary arm plate; the left steering joint and the right steering joint are connected with a left inclination joint and a right inclination joint through the steering shafts; the two ends of each steering pull rod are hinged to the left steering joint and the right steering joint through shafts in the connecting holes of the upper rotary arm plates; piston rods of steering oil cylinders fixed to a front axle are hinged to the left steering joint and the right steering joint through shafts in the connecting holes of the lower rotary arm plates; the lower rotary arm plates and the upper rotary arm plates in the left steering joint and the right steering joint form a laminated type steel knot welding type steering arm; the maximum inner rotary angle of a front axle steering joint can be increased to 50 degrees, the turning radius of an overall vehicle is reduced, moving of the overall vehicle on a site is conveniently carried out, and interference between the steering oil cylinders and the steering pull rods is avoided.
