Leave walking room around the parked tractor if you need to service, refuel or connect implements indoors.

A 104.3 in wheelbase means the approach into the storage bay matters, not just the doorway width.
Storage FAQ
Will it fit in a garage?
The John Deere 6620 Premium is 186.1 in long, 91.2 in wide and height not captured tall, so a garage only makes sense if it beats those numbers with real clearance. A practical check is 10 ft wide and 24 ft deep.
What size door should I check?
Measure the real clear opening, not the advertised door size. You need it to clear the John Deere 6620 Premium’s height not captured height and 91.2 in width, with about 24 ft for the 186.1 in length.
Do attachments change the storage size?
Yes. If you park it with the loader or implement fitted, measure that setup; do not assume the listed 186.1 in length and 91.2 in width still describe the parked machine.
How much maneuvering room should I allow?
For this utility tractor, plan the outside approach as part of storage. The John Deere 6620 Premium is 186.1 in long with a 104.3 in wheelbase, so leave room to straighten before the front wheels reach the door.
