Abstract
A power take-off (PTO) arrangement is provided for transferring power between a work vehicle and an implement. The PTO arrangement includes a PTO shaft having a PTO flange; and a PTO transmission unit having an input shaft coupled to the work vehicle, an output shaft coupled to the PTO shaft, and a gear set coupling the input shaft to the output shaft such that the power is transferred at a speed ratio selected from at least two speed ratios. A PTO speed control system has a sensor arrangement proximate to the PTO shaft and configured to sense data associated with the PTO flange and generate a PTO flange output signal based on the PTO flange data and a control unit and configured to selectively enable and disable operation of the PTO arrangement based on the PTO flange output signal and the selected speed ratio.
