Kubota GT-21 Extra Dimension Notes
Size class note
The Kubota GT-21 has the footprint of a small compact tractor. It is sized more for acreage, yard work, loader jobs and tight property access than large field work.
Storage fit note
The Kubota GT-21 should be one of the easier tractors to fit under cover. With length 110.4 in (9 ft 2.4 in) / 2,804.2 mm, width 45.3 in (3 ft 9.3 in) / 1,150.6 mm, and height 74.6 in (6 ft 2.6 in) / 1,894.8 mm, attachments remain the wildcard.
Fitment note
The Kubota GT-21 dimension set is length at 110.4 in (9 ft 2.4 in) / 2,804.2 mm, width at 45.3 in (3 ft 9.3 in) / 1,150.6 mm, and height at 74.6 in (6 ft 2.6 in) / 1,894.8 mm. Keep some margin for tire bulge, steps, fenders, lights and attachments.
Wheelbase note
The Kubota GT-21 lists wheelbase at 48.4 in (4 ft 0.4 in) / 1,229.4 mm. Use this when comparing actual chassis size.
Ground clearance note
The Kubota GT-21 clearance figure, 4.3 in / 109.2 mm, is worth checking for row crop, stubble and uneven ground.
Tread width note
The Kubota GT-21 tread-width listing gives 36 in (3 ft 0 in) / 914.4 mm at the front and 36 in (3 ft 0 in) / 914.4 mm at the rear. Use this when checking row spacing or wheel-stance fit.
Storage Tips
For the Kubota GT-21, small-shed storage is realistic if the opening has usable margin, not just a perfect-on-paper fit.
Leave walking room around the parked tractor if you need to service, refuel or connect implements indoors.
For small compact storage, height and attachment length are usually the traps.
Wheelbase is 48.4 in, so leave room to line it up cleanly rather than forcing it through a tight angle.
Storage FAQ
What size garage will fit the tractor?
A tight garage is a bad match when the machine is 110.4 in long, 45.3 in wide, 74.6 in tall, and 48.4 in wheelbase. The Kubota GT-21 needs a clear opening and bay closer to 7 ft high, 8 ft wide, and 15 ft deep for comfortable storage.
What size door should I check?
The door should be bigger than the tractor by about 8 in of height margin and 12 in of side margin. That puts the target around 7 ft high, 8 ft wide, and 15 ft deep.
Do attachments change the storage size?
Yes. A loader mainly adds depth and sometimes height; a rear implement adds depth; a mower deck or tire setting can add width beyond the listed 45.3 in.
How much maneuvering room should I allow?
With a 48.4 in wheelbase and 45.3 in width, leave enough straight approach to line up before the doorway. About 12 ft of clear approach is the cleaner target.
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 kubotausa.com website for official information.
