Deutz-Fahr AgroStar – Large-Tractor Series of the Early 1990s: Forerunner of the Agrotron, with Four- and Six-Cylinder Engines, 65 to 169.3 kW and Operating Weight from 4,150 to 8,510 kg
Deutz-Fahr built the AgroStar series from 1990 to 1997 as its then top-tier range, before the Agrotron series took over that role. According to the register, output of the recorded models ranges from 65 to 169.3 kW, with models rated in horsepower spanning 91 to 230 hp, using four- and six-cylinder engines with displacement from 4,086 to 9,572 cm³.

Recorded operating weight runs from 4,150 to 8,510 kg, wheelbase from 2,450 to 2,972 mm, and top speed of the listed models spans 30 to 40 km/h. Model names followed a scheme combining cylinder count and power class, such as AgroStar 6.71 for a six-cylinder unit in the 70-class power band.
The AgroStar series targeted large arable farms and formed the flagship of the Deutz-Fahr range before being succeeded by the Agrotron series. Buyers of a used model should check the turbocharger and charge-air cooler, as these varied by power level.
With rated outputs from 65 to 169.3 kW, the AgroStar series falls within ISO 730 Category II to III for the rear three-point hitch, with a standard dual-speed power take-off at 540 and 1,000 revolutions per minute for heavy implements. Deutz-Fahr as a tractor brand belongs to the Italian SDF Group (SAME Deutz-Fahr), which is a separate company from the Cologne engine maker Deutz AG; both still supply spare parts for their respective ranges today.

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.
- Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
- 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.
