Around 150 units were built. The 380 series covers 4 models. Rated output within it ranges from 10 to 20 hp; the 381S sits in the middle of that range with 14 hp. Its immediate neighbours are the 382 below it with 10 hp and the 383 above it with 20 hp. 6 Stihl models across 2 series are on record.

Stihl 380 – small tractors 381, 381S, 382 and 383 with single- and twin-cylinder diesel engines from 7 to 15 kW, displacement 534 to 1,004 cm³, unladen weight between 690 and 1,030 kg

The 380 series brings together four closely related small tractors: the 381, 381S, 382 and 383 types. The continuous numbering from 381 to 383 shows a model sequence with rising motorisation, while the S suffix on the 381S denotes a separate version within the base 381 type. All four models are built as single- or twin-cylinder diesel tractors with comparatively small displacement, placing them in the lightest class of tractors listed here in the register.

The register lists four versions here with 7.4 to 14.6 kW from single- and twin-cylinder diesel engines with 534 to 1,004 cm³ displacement. Rated speed lies between 1,890 and 2,000 rpm, unladen weight ranges from 690 to 1,030 kg with lengths from 2,415 to 2,825 mm, widths from 1,250 to 1,470 mm and heights from 1,240 to 1,640 mm.

With unladen weights under a tonne and single- to twin-cylinder engines, the 380 series sits in the smallest tractor class, of the kind used for specialty crops, small sideline farms or municipal maintenance work, where manoeuvrability and low weight mattered more than high pulling power.

When buying used, with engines this small the condition of the injection pump and fuel system, tightness of the crankcase and valve cover, wear on the clutch and gearbox, and corrosion on sheet metal parts and wings are especially important to check. Parts availability for such small tractors is limited and runs mainly through specialist used-parts dealers.

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 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.
