HYDRAULIC SYSTEM FOR WORK MACHINE, WORK MACHINE, AND METHOD FOR CONTROLLING HYDRAULIC SYSTEM
A coupler cylinder (21) is driven between a locked state and an unlocked state of a bucket (6) by being supplied with hydraulic oil. A main pump (23) supplies the hydraulic oil to the coupler cylinder (21). A pressure increasing valve (25) controls the supply of the hydraulic oil to the coupler cylinder (21). A controller (30) controls drive of the pressure increasing valve (25). The controller (30) instructs the pressure increasing valve (25) to stop the supply of the hydraulic oil to the coupler cylinder (21) based on pressure in an oil passage between the main pump (23) and the coupler cylinder (21).
