Deutz Allis DX 4.70: air-cooled four-cylinder standard tractor of the DX-4 range with 4,086 cm³ displacement, 90 hp (65.9 kW) and 3,850 kg weight
Deutz Allis was the joint brand under which the Cologne engine maker Deutz and the American manufacturer Allis-Chalmers offered tractors for the North American market in the 1980s. The DX 4.70 belongs to the DX-4 range, the mid output segment of this cooperation.

The four-cylinder diesel engine with 4,086 cm³ displacement is air-cooled and produces 90 hp, or 65.9 kW, at 2,300 rpm, with torque of 320 Nm. At 3,850 kg weight, 4,170 mm length, 2,304 mm width and 2,640 mm height, the DX 4.70 ranks among the more powerful four-cylinder standard tractors of its class.
A top speed of 30 km/h places the DX 4.70 in driving licence category L (up to 40 km/h). The air-cooled four-cylinder engine with 320 Nm of torque is built for tillage with larger cultivators and ploughs and for transport work with trailers, as was typical in North American arable farming.
When buying a DX 4.70, check the condition of the cooling-air ducting on the four-cylinder engine, as Deutz Allis tractors of these years depend on a properly working cooling fan. Also check the clutch and gearbox under high drawbar load, the hydraulic pump, and the availability of spare parts, which is more limited since the end of the Deutz Allis brand than for current ranges. The condition of the exhaust manifold and air intake screen is also worth checking, since restricted airflow overheats an air-cooled four-cylinder quickly under load.

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.
