I too am looking for a 46" replacement deck. Just cracked it the other day. I have a Murray 46561x8 . They are near impossible to find up here in the North East.
If I research shipping options from Florida would you be willing to consider shipping one?
If anyone else reading this knows where I could find a replacement deck frame (the rest of teh components on my deck are ok) in the NY/NJ/CT/MA area that would be really helpful. Willig to drive 4 hours out of CT if I must to pick one up.
