Abstract
A pilot neutralizing system of a work vehicle may include a pilot neutralizer and a flow control apparatus. The work vehicle may include a frame assembly and an actuating assembly to pivot the frame assembly. The pilot neutralizer is hydraulically coupled between an operator control member and a steering valve to selectively direct a pilot signal to the steering valve and is hydraulically coupled to a reservoir via a reservoir line. The pilot signal is used to switch the steering valve to change a direction of a hydraulic fluid flowing from the steering valve to the actuating assembly. The flow control apparatus is hydraulically coupled to the reservoir line and used to change a draining rate of the pilot signal to the reservoir. When the articulation position reaches a cushion region during steering, the pilot signal drains back through the flow control apparatus to the reservoir.
