John Deere 820 Extra Dimension Notes

Wheelbase note

Storage Tips
Garage-style storage may work, but judge it against 8 ft high and 15 ft deep, not the exact tractor dimensions.
If the tractor is stored with a loader or rear implement, add more bay depth than the bare length suggests.
This size is still realistic for smaller sheds when the approach is straight and the attachments are removed.
The 74.4 in wheelbase is useful when judging trailer position and shed maneuvering room.
Storage FAQ
Will it fit in a garage?
This tractor’s 135 in length and 78.7 in height make ordinary garage storage doubtful unless the opening is oversized. Use 8 ft high, 15 ft deep as the practical benchmark.
What size door should I check?
The clean check is 8 ft high, the tractor width plus side clearance wide and 15 ft deep. That gives margin over the listed 78.7 in height, width not captured width and 135 in length.
Do attachments change the storage size?
Yes. Check attachments against all three numbers: 78.7 in for overhead clearance, width not captured for side clearance and 135 in for bay depth.
How much maneuvering room should I allow?
Use the 74.4 in wheelbase plus the 135 in length together. The tractor may clear the doorway but still need space to swing the front or rear around.
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.
