Recorded operating weight runs from 2,540 to 3,400 kg, wheelbase from 2,012 to 2,327 mm, and top speed of the listed models spans 30 to 40 km/h. Model names followed a cylinder-count-dot-power-code scheme, such as DX 3.90 for the most powerful three-cylinder model in the series.
The DX 3 series complemented the larger DX series from below in the Deutz-Fahr range, aimed at smaller farms as well as grassland and orchard operations. For a used model, check the gearbox variant, as simple and powershift versions were offered in parallel.
In tractors of this power class, the 1980s increasingly saw the two-speed PTO with 540 and 1,000 rpm, switched depending on the attached implement; the three-point hitch matched category I at the lower end of the range and already category II under ISO 730 at its more powerful edge. Deutz-Fahr's shift from naturally aspirated engines to turbocharging at this time began first with larger series; the DX 3 models remained naturally aspirated. Tractors with a category II hitch can be matched to category I implements using suitable reducer bushings; the reverse is not possible without modification.

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.
