John Deere X354 / X370 Lawn Tractor with 42-inch Width with Bagger?

[mike.fitzgibbons66]

The 42" x354 and X370 width with mower (deflector raised for storage) is 51.2".... How much does a bagger add? I have a 58" gate opening and want to make sure i have a wide enough opening for one of these beauties.
