I purchased a new 72" king kutter professional tiller for my 2038R. Went to install the slip clutch end of the PTO shaft and found they were too lazy to cover the splines when they painted it, so after taking the time to scrape it off and grease it I made an attempt to slide the shaft on. It wouldn't seat, took it off and tried again and pushed hard. I dont feel like its fully seated (see pictures) and now I cannot get it off by pulling on it. I even put a pry bar on it and pushed the spring pin, still nothing. To me the spring pin doesnt appear to be fully seated so I'm not sure if its locked in place. Anyone else have one of these? Looking to verify if the shaft is seated all the way on the gearbox spline.
