The Kubota B7100D rolled off the line in 1981 as a tractor. The three-cylinder engine, displacing 760 cm³, produces 11.9 kW.
It measures 2 m in length and 1.02 m in width. Unladen, it tips the scales at 490 kg.
Within the range, rated power spans from 8.9 to 129 kW; with 11.9 kW, the B7100D sits at the bottom end. Directly alongside are the B7001D with 10 kW below and the B 1700HD-B3-4X4 with 12 kW above.
Kubota – other models: the collective page of tractors outside the named ranges, from the B and L compacts (B7100, L3350) through the M range to the M7 and the smallest tractors of the 1970s, 9 to 129 kW, Kubota engines of 0.5 to 6.1 litres
This page gathers the Kubota tractors the register could not assign to a named range – the Osaka group that began in 1890 as a foundry, built its first tractor in 1960 and came to North America and Europe with compact tractors in the 1970s, where it dominates the class under 50 hp to this day. The type logic: the letter gives the range – B for the compacts under 30 hp, L for the mid-range up to 60 hp, M for the full-size tractors above, BX and GR for lawn tractors – the number roughly the hp class (B7100 about 16 hp, L3350 about 33 hp, M9540 about 95 hp), D and DT four-wheel drive, HST the hydrostatic transmission, GL, GX and X equipment lines; since 2014 Kubota has also built tractors up to 170 hp with the M7 range from the Bierne plant in France. The engines are throughout Kubota's own diesels – the D and V series of 0.5 to 6.1 litres, which Bobcat, Manitou and many other makers also source.

The register lists here 657 versions with 8.9 to 129 kW from two- to five-cylinders of 500 to 6,129 cm³, PTO outputs from 14 to 140 hp, lift capacities from 300 to 5,350 kg, unladen weights from 440 to 7,350 kg, lengths from 1,800 to 4,940 mm and widths from 900 to 2,795 mm.
Kubota is the world's largest maker of compact tractors and market leader in Japan, North America and Southeast Asia; in Europe the brand gained a foothold through municipalities, horticulture and hobby farms and is growing into agriculture with the M range.
On used tractors, operating hours, engine condition (Kubota diesels are regarded as long-lived), hydrostat or clutch, four-wheel-drive clutch, front loader and mower PTO, on younger models the exhaust aftertreatment count; parts run through the dense Kubota network.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
