Steyr 80-86

In 1949 Steyr introduced the single‐cylinder Model 80, whose water-cooled pre-chamber diesel engine developed 13 hp. The engine was part of the load-bearing structure, and the engine, clutch and gearbox were all placed on the left side of the centerline. It had 4 forward gears plus 1 reverse. At launch electric start and hydraulic lift were optional extras, but differential lock, steering brakes and both hand and foot throttle were standard. A crawling gear was available as an accessory, which increased the gearbox to 5 forward and 4 reverse gears. The original color was a dull green, later changed to a brighter shade of green. In 1953 output was raised to 15 hp.

In 1950 a parallel model called the 80a was introduced; its main difference was larger 36″ wheels. Another special version was the 80s, which was 40 cm narrower.

In 1955 the 84 models appeared. Power had been increased to 18 hp. The wheels were larger and the color scheme was red with yellow rims. The electrical system was upgraded from 6 V to 12 V. The 84e featured a faster 5 + 5 gearbox and a suspended front axle.

In 1964 the 86 models were launched, with styling updated to match the newer lineup. The seat was improved and the instrument panel redesigned.

A total of no fewer than 94 000 single-cylinder Steyrs were produced.
