Abstract

PURPOSE: To simplify the structure while changing over a pump as a driving source for feeding liquid to an actuator to a differential lock condition by remote operation, by driving said pump by utilizing the rotary driving of a differential case.
CONSTITUTION: A differential gear 9 is disposed into a carrier 8 for a front wheel of a tractor. The differential gear 9 is differentially locked at the desired time by means of a differential lock 24 produced by providing splines, which are each formed to an inner circumferential surface of the differential gear wheel 10 and an outer circumference of one of differential side gear 13, with discs 25. In this case, a driving pump 21 for differential lock equipped with a pump gear 22 engaging with a pump driving gear 23 mounted to an outer circumference of a differential case 11 is installed to said carrier 8, and compressed oil formed by means of the pump 21 is introduced to said differential lock 24 through an oil path 27 while a valve 29 is opened through an operating rod 32 when the differential lock does not work.
