Deutz-Fahr AgroCompact 3.90 F/S: narrow-bodied air-cooled four-cylinder tractor with 4,085 cm³ displacement, 75 hp (55.2 kW) and just 1,200 mm width
Deutz-Fahr built the AgroCompact range as compact, narrow-bodied tractors for tasks where standard tractors are too wide. The AgroCompact 3.90 F/S belongs to this narrow body style.
Read on 3 more paragraphs
The four-cylinder diesel engine with 4,085 cm³ displacement is air-cooled and produces 75 hp, or 55.2 kW, at 2,350 rpm, with torque of 250 Nm. At just 1,200 mm width, with 2,250 kg weight, 3,470 mm length and 2,100 mm height, the AgroCompact is markedly narrower than comparably heavy standard tractors.
With a top speed of 30 km/h, the AgroCompact 3.90 F/S falls into driving licence category L (up to 40 km/h). The narrow track width of 1,200 mm suits the machine to work in tight lanes, such as between row crops or in plantings with narrow row spacing, where a standard tractor would not fit.
When buying an AgroCompact, check the condition of the narrow axles and steering joints, which see greater strain working in tight lanes. Also check the cooling-air ducting of the air-cooled four-cylinder engine, the clutch and gearbox, and the availability of spare parts for this narrow special body style. The front hydraulics and the couplings for narrow implements should also be checked, since implements built specifically for this narrow range have become scarce, and finding replacements often takes considerable effort.

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.
