Larry, Does the tractor look like the 4618000? That is a Noma tractor, but Murray owned. I have never seen a Murray model with a T in it, so that is kind of throwing me. If it's a "regular" Murray tractor, any 46" deck ipl 2002 - 2005 will work. Actually, even a 1997 -2005 deck ipl would work, the only difference being a mandrell update in 2002.
