What kind of accessory are you planning to operate? Some PTO's are able to reverse directions for driving a winch or some other part that needs to turn both ways, while others that run something like a hydraulic pump for a dump bed only need to turn one direction. There are usually some PTO's listed on Ebay, so don't forget to look there.
