The Deutz‑Fahr 6140 is part of the tractor range from this manufacturer. It is equipped with a 4‑cylinder engine with a displacement of 4,038 cc. Key dimensions are 4,360 mm in length, 2,540 mm in width and 3,000 mm in height, with a wheelbase of 2,419 mm. The curb weight is 5,580 kg and the fuel tank holds 230 L. The transmission provides 40/40 gear ratios and the lift category is Cat II/III.
Rated at 144 hp (105.18 kW) at 2,100 rpm, the engine delivers a maximum torque of 628 Nm. These figures allow the tractor to pull medium‑size implements and handle field tasks that require high pulling force. The relatively high curb weight reduces ground pressure, which is advantageous on sensitive soils. A large 230 L tank enables long operating periods without frequent refuelling, and the 40‑gear gearbox offers fine speed steps for precise work.
The 6140 is suited for typical applications in the middle‑size tractor segment, such as operating plows, seeders and sprayers on medium to large fields. Its combination of power, torque and robust construction meets the expectations for versatility and endurance expected in this size class.
Deutz-Fahr – other models: the collective page of tractors outside the named ranges, from the MK3-generation classics through the 4 and 5 series to models with KEYLINE and TTV specification
This page gathers the Deutz-Fahr tractors the register could not assign to a named range – from older model years such as the 100 to 260 MK3 range through the four-cylinder 4 series (4.5, 4.56, 4.85, 4006) to the broad mid-range 5 series with types from 5060 to 5120. Deutz, founded in 1864 by Nikolaus Otto in Cologne as an engine works, merged its tractor business with that of the Fahr machinery works of Gottmadingen in 1968 to form Deutz-Fahr; since 1995 the brand has belonged to the Italian SAME-Deutz-Fahr group (SDF), which builds the tractors in Lauingen on the Danube in Bavaria. In the 5 series the type designation clearly tracks the power: the 5090 has about 90 hp, the 5105 about 105 hp, the 5115 about 115 hp; the suffixes KEYLINE, ECOLINE and TTV denote the equipment level and stepless transmission, D and DT four-wheel drive.

The register lists here 213 versions with 35 to 211.1 kW (47 to 268 hp) from three- to six-cylinders of 1,758 to 7,146 cm³, unladen weights from 2,800 to 10,725 kg, gross weights from 4,500 to 16,000 kg, lengths from 2,980 to 5,820 mm, widths from 2,008 to 2,944 mm and heights from 2,020 to 3,225 mm.
Deutz-Fahr is one of Europe's longest-established tractor brands and a fixture in the mid and upper power segment in Germany, Italy and much of southern Europe; the brand's distinctive green paint and cab design have shaped its image for decades.
On used tractors, engine condition and rust on the bodywork count on the older MK3 and 4-series models, on the 5 series the transmission (mechanical, KEYLINE or stepless TTV), hydraulics and electronics, and on the DF and G variants the condition of the four-wheel-drive clutch; parts run through the SDF network and in part through Same and Lamborghini workshops.

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.
- Shift the gearbox cold and warm — jumps only show up at temperature.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
