Brandenburger Traktorenwerke KT - Prototyp

The KT 732 carries a four-cylinder diesel engine with 8,590 cm³ of displacement, producing 63 hp, or 46.34 kW, at 1,150 rpm, and works with evaporative circulation cooling rather than a radiator with a water pump. At 4,940 kg, 3,985 mm long, with a 2,250 mm wheelbase and 1,700 mm width and 2,280 mm height, the machine reaches a top speed of 9.5 km/h. At 1,150 rpm the engine ran at a markedly lower speed than typical tractor diesels of later decades, favouring durability over specific output.

Evaporative circulation cooling without a radiator was a simple, low-maintenance solution for slow-running tractor engines, in which the cooling water stayed in circuit only through evaporation and refilling. The low top speed of 9.5 km/h points to a purely field-work machine, with no role in road transport.

With a test vehicle such as this prototype, the first question is whether it is genuinely the original vehicle or a later reconstruction, since prototypes in museums and collections have often been reworked more than once. Technically, the condition of the circulation cooling, the tightness of the fuel system and cracking of the engine block after decades of standing should be checked.
