Title: SELF-ADJUSTING PTO CLUTCH ENGAGEMENT METHOD BASED ON REAL-TIME INERTIAL LOAD ESTIMATION
Abstract:
A method (110) for controlling PTO clutch engagement includes determining (112) a first change in clutch speed based on an inertial load of a PTO implement (23). The method also includes determining (114) a second change in clutch speed based on a threshold amount of energy of a PTO clutch (24). The method further includes determining (116) a third change in clutch speed between the first change in clutch speed and the second change in clutch speed. The method also includes adjusting (118) a clutch current based on the third change in clutch speed.
