Holder AR (38/39): air-cooled single-cylinder two-stroke compact tractor from the Auto-Rekord series with 335 cc displacement, 4.8 kW output and 480 kg weight, built 1937 to 1941
Holder, based in Metzingen, Baden-Württemberg, was in the late 1930s among the smaller German manufacturers offering simple compact tractors to farms that had previously relied on horse teams or manual labour. The AR (38/39) from the Auto-Rekord series was built between 1937 and 1941.

The single-cylinder engine of 335 cc runs on a two-stroke petrol-oil mixture, is air-cooled and delivers 4.8 kW, or 6.5 hp. At a weight of 480 kg, a length of 2,000 mm, a height of 900 mm and a width of 1,100 mm, the AR (38/39) reaches a top speed of 7 km/h.
A two-stroke tractor this small and light, with a top speed of only 7 km/h, was built for the simplest tasks of a small holding: light tillage, driving small stationary equipment through a belt pulley, and hauling light loads, not for field work on a larger scale or for any meaningful road use beyond the farmyard.
When buying such an old two-stroke compact tractor, the correct petrol-to-oil mixture ratio for the engine, the condition of the piston and rings, which see the wear typical of two-stroke engines, and the cooling fins on the cylinder and rust on the frame and sheet-metal parts all matter. Spare parts for a model this old can now practically only be found among collectors of historic agricultural machinery and vintage-engine specialists.
