Abstract:
A control system controls movement of a work implement of a work vehicle and includes a pump, a first actuator in fluid communication with the pump, a first control valve fluidly positioned between the pump and the first actuator, a first proportional relief valve fluidly positioned between the pump and the first actuator, a second actuator in fluid communication with the pump, a second control valve fluidly positioned between the pump and the second actuator, and a second proportional relief valve fluidly positioned between the pump and the second actuator. The first proportional relief valve permits flow of fluid from the first actuator upon an impact at a first set force. The first set force is adjusted by a user. The second proportional relief valve permits egress of fluid from the second actuator upon an impact at a second set force. The second set force is adjusted by a user.
