I have a LT2180 with the 42" deck and I was looking to change the deck to the 48" deck from a 2165. Does anyone know if there are any issues with this ? I assume I will have to change the drive belt, but not sure if there are any other issues. Anyone out there have a PDF copy of the manual for a 48" deck ? I really like this tractor, just want a little bigger deck, I know the Vanguard 18HP will handle it fine.
