Abstract:
A hitch assembly for a work vehicle, the hitch assembly comprising:a first draft link adapted to be pivotably coupled to the work vehicle;a second draft link adapted to be pivotally coupled to the work vehicle, wherein the first and second draft links are pivotable relative to one another;a first linear actuator having a first end adapted to be pivotably coupled to the work vehicle and a second end pivotably coupled to the first draft link, wherein the first linear actuator actuates between at least three lengths including a fully extended length, a fully retracted length and at least one length therebetween;a linear member having a third end adapted to be pivotably coupled to the work vehicle and a fourth end pivotably coupled to the second draft link, wherein the first linear actuator is actuatable to different lengths to pivot the first draft link relative to the linear member;a first sensor configured to generate a first signal indicative of the at least three lengths of the first linear actuator; anda control circuit coupled to the first sensor and configured to generate a control signal in response to the first signal, wherein the linear actuator actuates in response to the control signal.
