My 1025R has only 41 hours on it, with less than 10 of those with the mower deck. Yesterday when I was mowing the deck dropped and I cut half my yard lower than I originally had set it at. If I raise / lower the deck, depending on how the knob is clicked into the position, the deck with drop to a lower height.
I got under the tractor and the adjustment gear is already worn on the edge of the height setting I use. You can feel the metal curling over the edge. This is ridiculous for only a few hours. Is something out of adjustment or did I just end up with a faulty part? I did notice that when turning the knob to go to a lower setting it locks in on the small edge of the gear. If I then turn it slightly towards a higher setting it will hold on the larger part of the gear. Almost like the detent spring isn't strong enough to keep it in the center of the ledge. It also doesn't have full engagement as the wear is only on the edge and not across the entire ledge.
