Thanks for the feedback on the cuts between the two. I have been wondering about that.I would take that to a local metal shop and I'd bet for $75 - $125 they fix you right up. A 48 inch replacement used is going to go $500 and a used 50 inch deck will run you $250 - $450 depending on condition. The 50 inch deck has an amazing cut the 48 inch deck is good but not like the 50 inch deck!
So, it seems like most think I should go about repairing the existing deck. So, my next question would be: Has anyone made any mods to strengthen the deck on this side? If so, pictures would be great. I was thinking of maybe adding some round bar to the bottom, similar to what's on my 4110's deck. Not that I plan on running into things, but this seems to be an inherently weak spot of the deck based on the others I've seen with roughly the same problem.
