Abstract

Systems and methods are disclosed herein for adaptive power take-off (PTO) droop control for a self-propelled work vehicle having an engine and a PTO device directly mechanically coupled to the engine. The systems and methods enable user selection of at least one of a target ground speed or a target power take off (PTO) speed. The systems and methods are responsive to at least one of the selected target ground speed or the selected target PTO speed to identify a maximum transmission ground drive efficiency corresponding to an effective droop value within a defined droop range. The systems and methods control an actual engine speed and an actual transmission ratio to respective adjusted target values corresponding with the maximum transmission ground drive efficiency.
