hey everyone, i just got registered after surfing through this site. it is amazing how much info everyone can share when we all work together. i've been having a problem getting a smooth, even cut from my exmark 48'' rider. there is either a tiny strip about one inch thick that just doesn't get cut. i keep my blades sharp and tire pressure even. it sometimes happens in two spots. i think it might have something to do with the bolt(s) under the deck that hold the blades on (sorry for the laymans terms but i'm not really mechanically inclined) am i right? could those be the one inch strips that aren't being cut? this site is the best thing i've found on the net so far, whoever started this is now my best friend.
