Kubota GB135 Extra Dimension Notes
Size class note
The Kubota GB135 size class is best described as small compact tractor. It is sized more for acreage, yard work, loader jobs and tight property access than large field work.
Wheelbase note
The Kubota GB135 wheelbase reads 50 in (4 ft 2 in) / 1,270 mm. Use it as a comparison number across similar tractors.
Ground clearance note
The clearance number for the Kubota GB135 is 9.8 in / 248.9 mm. This helps separate field-ready sizing from simple storage dimensions.
Tread width note
The Kubota GB135 tread-width values are listed as 48.4 in (4 ft 0.4 in) / 1,229.4 mm at the front and 48.4 in (4 ft 0.4 in) / 1,229.4 mm at the rear. That tells you more than overall width alone.
Storage Tips
Measure the lowest overhead point, not the tallest part of the shed roof.
Compact size helps, but a loader or mower can still make the parked footprint much bigger.
A 50 in wheelbase means the approach into the storage bay matters, not just the doorway width.
Storage FAQ
What size garage will fit the tractor?
With 70.3 in height and 40.9 in width, the doorway is the first limit; with 78.9 in length, bay depth is the second. Start with 7 ft high, 8 ft wide, and 15 ft deep, not the bare dimensions.
What size door should I check?
Use 7 ft high, 8 ft wide, and 15 ft deep as the door-and-bay target. That is based on the tractor’s 70.3 in height, 40.9 in width and 78.9 in length, plus working clearance.
Do attachments change the storage size?
Yes. Keep the bare dimensions in mind: 78.9 in long, 40.9 in wide and 70.3 in tall. Then add attachment overhang, folded ROPS/cab height and mower or tire width.
How much maneuvering room should I allow?
A short answer: give the tractor enough room to approach straight, not just enough room to fit inside. With 50 in wheelbase, about 12 ft outside the opening is a better check.
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.
