Abstract
PURPOSE: To prevent wheels from slipping and maintain its stability by enabling to operate a DIF-lock device automatically when a traction load over a set value is given to a machine which draws a work machine as draught-controlling it.
CONSTITUTION: When a prescribed work is carried on by tractor running and drawing, for example, a plow, the output of a detector 33 to detect a traction load is comapred with the set value of a setter 34 in a comprator 35, and an oil pressure device to control the plow is driven via an oil pressure control device 37 on the basis of the result of the said comparison for carrying on a prescribed draught-control. When the output of the detector 33 surpasses the set value, a DIF-lock signal is given to an actuator 22 from a contol device 38. Thereby, a DIF-lock shaft 23 of a rear wheel DIF-lock device 16 is operated, and lock pin 27 on a DIF-lock clutch 25 is fitted into a pin hold 26 of a DIF side gear 21 for intermitting the operational function of a DIF device 15.
