Storage FAQ
Will it fit in a garage?
If your garage door is close to 147.3 in tall or 173.3 in wide, count it as too tight. The safer check for the John Deere 9R 390 is around 16 ft high, 19 ft wide, and 36 ft deep.
What size door should I check?
Use 16 ft high, 19 ft wide, and 36 ft deep as the door-and-bay target. That is based on the tractor’s 147.3 in height, 173.3 in width and 312.8 in length, plus working clearance.
Do attachments change the storage size?
Yes. Keep the bare dimensions in mind: 312.8 in long, 173.3 in wide and 147.3 in tall. Then add attachment overhang, folded ROPS/cab height and mower or tire width.
How much maneuvering room should I allow?
The tractor can clear the door and still be annoying to park if the approach is angled. With 173.3 in width and 312.8 in length, keep the entry path straight and open.
Official information note
Mistakes do happen. Tractor dimensions can change by year, tire setup, cab/ROPS setup, attachments and market. Please check the operator manual, build sheet and official deere.com website for official information.
