Frieg Holder AG 3: water-cooled three-cylinder diesel compact tractor from the A series, 1,500 cc displacement and 990 kg weight, built around 1970
The AG 3 from the A series is a compact tractor of the kind built around 1970 for farms with limited space or for specialist crops, where an ordinary large field tractor would have been too unwieldy.

The AG 3 is powered by a water-cooled three-cylinder diesel engine of 1,500 cc, producing 30 hp, or 17 kW. At a weight of 990 kg, a length of 2,300 mm, a height of 1,200 mm and a width of 870 mm, with a wheelbase of 1,130 mm, it is a very compact tractor with a top speed of 19 km/h.
The small overall dimensions and low weight make a compact tractor like this manoeuvrable in tight spaces, for instance between rows in specialist crops, in greenhouses or on small, irregularly shaped plots that a large standard tractor could not access. For heavy drawbar work or large mounted implements, however, the output of a three-cylinder engine this size is not sufficient, and the low ground clearance further limits travel over uneven terrain.
When buying such an old and small tractor secondhand, the condition of the radiator and water pump of the water-cooled engine, and wear in the clutch and gearbox, matter most. Also worth checking are the brakes and visible corrosion on sheet-metal and frame parts; spare parts for such a small and old compact tractor are now usually only available through specialist suppliers, often only to special order.

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.
