Hela D-Reihe
5 models in this series
Hela D37 to D415 – small German standard tractors of the post-war years: D prefix for diesel drive, single- and twin-cylinder engines, 11 to 16.1 kW, 1.13 to 1.6 t service weight
Hela's D range belongs to the numerous small and mid-size standard tractors with which German makers drove the mechanisation of smaller farms in the post-war years, at a time when dozens of workshops across West Germany entered the tractor business alongside the established names. The D prefix in the type designation, as with many makers of the period, stands for diesel drive; the model numbers from 37 to 415 order the range roughly by power class, with the smaller versions running one and the larger two cylinders.

The register lists 5 versions with engines of 1,082 to 2,198 cm³, 1 to 2 cylinders and outputs of 11 to 16.1 kW. Service weights range from 1,130 to 1,600 kg, lengths from 2,560 to 2,900 mm, widths from 1,500 to 1,540 mm and heights from 1,250 to 1,600 mm.
Like many smaller German tractor brands of the 1950s, Hela served a niche alongside the large makers Deutz, Fendt and Eicher, aiming at farms that needed a simple, compact tractor for basic work without being able or willing to afford one of the pricier branded tractors of the day.
On these rare small tractors, operating hours, the condition of injection pump and cylinder head, clutch and gearbox, steering linkage, and rust on frame and sheet-metal parts all count; spare parts are practically obtainable only through specialist vintage-tractor collectors and replica workshops.
