The invention discloses a novel crawler tractor power transmission system which comprises a front transmission shaft, a shunt box, a belt transmission system, a continuously variable transmission, anaxle box, driving wheels and a power output device. The power input end of the front transmission shaft is connected with external power, and the power output end of the front transmission shaft is connected with the shunt box; the shunt box is provided with an input shaft, an upper output shaft and a lower output shaft, and the upper output shaft is connected with the continuously variable transmission through the belt transmission system; the continuously variable transmission is connected with the axle box; a half shaft of the axle box is connected with the driving wheels on the two sides;and a lower output shaft of the shunt box is connected with a power output device and transmits power to a working device suspended by a tractor. The transmission system is split into several small-size assemblies connected through the transmission shaft or the belt, the manufacturing difficulty of the transmission system is reduced, and the maintenance convenience is greatly improved.
