Hanomag A series – the early agricultural tractors from Hanover, AR 38 to GR 50, four-cylinder diesels of 5,195 cc, 38 to 50 hp

The Hanomag A series came from Hannoversche Maschinenbau AG in Hanover, which built agricultural tractors from the 1930s into the 1970s before giving up its farm-machinery division. The types listed here, AR 38, AR 50 and GR 50, carry their output in the name: the number after the abbreviation states the model's power in horsepower, from 38 to 50 hp. All three versions of the series are built around the same four-cylinder diesel engine of 5,195 cc, which reached the series' different power levels depending on tuning.

The register lists 3 versions here with 38 to 50 hp from the common four-cylinder of 5,195 cc at 1,100 to 1,300 revolutions per minute, kerb weights of 3,100 to 3,350 kg, lengths of 3,270 to 3,420 mm, widths of 1,660 to 1,750 mm and heights of 1,530 to 1,700 mm; one of the versions is additionally recorded as 28 kW.

In West Germany's post-war farming, Hanomag's A-series agricultural tractors competed directly with Deutz, Lanz and Fendt, and their power class covered the middle segment of peasant holdings, for which they handled ploughing, harvest-trailer and transport work.

When buying a used AR or GR model, the key points are the condition of the engine and injection pump, tightness of the cooling system, wear on steering and front axle, and corrosion on mudguards, bonnet and chassis; spare parts for the A series can now only be sourced through dealers specialising in vintage machinery and breakers, since Hanomag stopped farm-machinery production long ago.

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.
