I have a Sears 16.5 hp riding lawn mower with a worn out 46" mower deck and I have a nice 50" craftsman mower deck from the same year mower. Can I exchange them? Will the 50" fit on a 46"?

If you have both... try it and see... keeping in mind you might have to make some adjustments to the mounts to position it where it needs to be on yours.

SHouldn't take more than 15 minutes to find out if it will work.
