Schlüter S 350 / SF 3300: three-cylinder tractor rated at 25 kW, 2,926 cc displacement and 1,880 kg weight from the lighter S 350 range
Schlüter was a German tractor manufacturer based in Freising in Bavaria, building a wide power range from the 1930s until it ceased tractor production in 1993, from compact single-cylinders to the high-output large tractors it later became known for. The S 350 range belonged to the company's lighter programme.

The S 350 (SF 3300) is powered by a three-cylinder engine of 2,926 cc, producing 25 kW (34 hp) at 1,800 rpm. At a weight of 1,880 kg and a width of 1,774 mm, the tractor reaches a design top speed of 19 km/h. Height stands at 1,547 mm and length at 3,417 mm. The front carries 5.50-16 AS tyres, the rear either 11.2-28 AS or 10-28 AS.
A three-cylinder of this power class marks a light-to-medium field tractor, the kind used for grassland upkeep and light implements on smaller and mid-sized farms. The 19 km/h top speed falls within the L driving licence category, and the power take-off on tractors of this era usually ran at 540 rpm, while a three-point hitch was only becoming widespread at this power level.
Buying a used three-cylinder this old, the injection system and the condition of the cooling system deserve particular attention. Also worth checking at inspection are the sheet metal for rust damage, the condition of either rear tyre option fitted and the functioning of the brakes.

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.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
