lol jd, sounds like something i would let someone else do haha, but i tried some stuff tonite adjusting my deck wheels thought that was some of the problem, but not all of it, now its not as noticable but still there. an now that i look at it there seems to be no adjustments for anything tho level the deck, but you say that about the belt it has a tensioner spring that holds it all the time so unless it breaks then its tight an when it does none of the blades turn, but could i have a bearing in that pulley going? being 8 years old, but it just has 1400 or so hours, but as far as i know its been serviced regularly, not sure if there is grease fitting there but may have to grease or replace it. i keep the deck pretty clean i try to get rid of all the stuff i hit like bags or baleing twine stuff or anything i coulnt see. im going to try and get some pics up of whats going on, may take a day or 2.
