PROBLEM TO BE SOLVED: To provide a crawler traveling gear capable of traveling in grassland with soft soil with sufficient propulsion force, and suppressing roughening of a traveling track. SOLUTION: On an outer peripheral surface of a rubber crawler belt 8, a long lug 15a that reaches a belt outside end and a short lug 15b that does not reach the belt outside end are disposed alternately in a belt circumferential direction, and in an open angle shape and a staggered shape in a belt forward rotating direction F. At an outer end on a top portion grounding surface S in the long lug 15a, a tilting chamfering portion M1 facing in a lateral outside direction opposite to the belt forward rotating direction F is formed.
