Kraig,
Thanks for the information about wear points on the mower deck hanger. I have not been happy with the maximum height for my deck either (I think it is just a little over 3".)
I am using 2 adjustable lift links. Ran them both to the top and then backed one down enough to level the deck. I don't remember how much it helped, but I don't think it was a whole lot.
I thought that most of my problems were in the lift handle ratchet mechanism on the rockshaft of the 1250.
But, I can basically take that out of the equation by lifting the deck with the spring assist. So, you have me thinking that I need to take a serious look at the wear points that you have pointed out. I know that there is wear in the fork and shaft you mention.
Thanks again!
