Glad to see all that info on the PTO on a 129 , just what i needed! I just recived a new button for my 129 and looking below i see a flex washer and clip.well i think that i still don`t have all the parts for my cub pto . Hate having to run her with the pto running all the time.wish i new what i was doing lol like what holds on the brake pad? Don
