Some T-150K tractors manufactured by the Kharkov tractor factory were also sold in Finland, and more have come in used condition. The model was based on the T-150 crawler tractor, which came into production in 1970. Compared to its predecessor, the T-125, it was completely redesigned. Initially, the 9.15-liter V6 engine produced 160-165 hp, and from the early 1980s onwards, 175 hp. The T-150K featured hydrostatic frame steering, a suspended front axle, automatically engaging four-wheel drive that activated when the wheels slipped, air-operated brakes, and an air-assisted clutch. The transmission had a 4-speed partial power shift. In 1985, a new cab with larger windows was introduced. The noise level decreased from 87 dB to 84 dB. At the same time, the auxiliary engine start was replaced by a 24-volt electric start. The top speed of 1990s models increased from 28.4 to 36 km/h.

At the end of the 1990s, production of the SMD-63 engine ended. The main replacement became the 11.1-liter engine from the Yaroslavl factory, with the model equipped with it known as the T-150K-09. A rarer model, the T-150K-12, was equipped with a Kamaz engine.
