With the KT-12/12A, Belarus offers a model from the KT-12/12A series. Production: 1951–1955. The engine delivers 45 hp, has 6 cylinders, with a displacement of 5,550 cm³. Rated speed is 2,300 rpm. The machine is 4,500 mm long, 1,950 mm wide and 2,790 mm high. The unladen weight is 6,150 kg. The wheelbase measures 3,370 mm. Ground clearance is 500 mm. Top speed is 10 km/h. Transmission: 5/1. Drive: Kette. The engine is water-cooled. The fuel is Holzgas. Rated output across the Belarus range ranges from 37 to 450 hp; the KT-12/12A sits at the bottom of that range with 45 hp. Its immediate neighbours are the MTZ-1 below it with 37 hp and the MTZ-50X above it with 50 hp. Rated output across the Belarus range ranges from 45 to 450 hp; here the KT-12/12A sits at the bottom of that range with 45 hp. 412 Belarus models across 29 series are on record.

KT-12/12A: the wood-gas-generator tractor of 1951 to 1955, six-cylinder with 45 hp, 6,150 kg unladen weight, top speed 10 km/h

The KT-12/12A was built from 1951 to 1955, in the first post-war years of the Soviet Union, when fuel shortages encouraged the building of farm machinery with gas-generator drive: instead of diesel or petrol, the engine burns wood gas produced by an onboard generator fed with wood or charcoal. Tractors of this design eased the shortage of petroleum fuels in agriculture in the immediate post-war years, before diesel engines displaced wood-gas technology in the following years.

The six-cylinder engine of 5,550 cm³ displacement produces 45 hp at 2,300 rpm – a modest figure for a six-cylinder, reflecting the lower energy density of wood gas compared with liquid fuel. With an unladen weight of 6,150 kg, a length of 4,500 mm, a width of 1,950 mm, a height of 2,790 mm and a wheelbase of 3,370 mm, the tractor reaches only 10 km/h top speed, a pace that points to pure field work rather than road transport.

At 10 km/h the KT-12/12A lies far below the 40 km/h limit of today's driving licence category L; the low travel speed combined with a high unladen weight is typical of early post-war tractors built for draft power at the plough rather than for covering distance. The onboard gas generator required extra steps to light compared with an ordinary diesel tractor, plus regular refilling of wood or charcoal during work.

Surviving examples are museum pieces today; when acquiring one for a collection, what matters is the completeness of the gas generator, the condition of the boiler and gas lines, and the originality of the cab and sheet-metal parts. Because spare parts for the gas-producing plant are no longer made, the value of the vehicle usually comes down to the preserved condition of the existing generator.

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.
  • 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.
