The invention relates to a planetary steering mechanism of a caterpillar tractor, which is mainly constituted of an engine, a clutch, a gear box, a hydraulic pump, a right planetary mechanism, a half shaft driving wheel, a rear axle, a left planetary mechanism, a hydraulic motor and a central transmission device, wherein the steering mechanism is a dual-power steering mechanism, that is to say, the output power of the engine is separated into walking drive and steering control through the gear box; the walking drive and the steering control are parallelly transmitted and converged at the planetary mechanisms; after the output power of the engine goes through the clutch and the gear box, one of the output power of the engine goes through the gear box, the central transmission device, the planetary mechanism whose speed is reduced and the half shaft driving wheel; the other one of the output power of the engine goes through the gear box, the hydraulic pump, a control valve and the hydraulic motor; and the two branches of output power of the engine are converged on the planetary wheel. According to the invention, the caterpillar tractor has the advantages of continuously stable steering and small steering diameter; the effort is saved when steering; and the work efficiency and the work quality of the tractor are greatly improved.
