In 1956, the HTZ-7 was replaced in production at the Kharkov factory by the DT-14, which had a 14 hp diesel engine. The transmission, rear axle, and the trailer hitch attached to the rear assembly were the same as in its predecessor. The engine was single-cylinder, water-cooled, and four-stroke. In the first DT-14, starting was done with a crank handle, and in the developed DT-14A version, starting was done with gasoline. In 1957, the DT-14B was introduced, which had electric starting and a two-function lift device. It had 4 forward and 4 reverse gears; with a direction reverser and a crawler gear, it had 5 forward and 4 reverse speeds. The clutch was manually operated. There were separate brake pedals for steering brakes on the left and right edges, and in addition, there was a main brake pedal. The DT-14 was a so-called reversible tractor: the seat could be moved to the other side of the vertical steering column by loosening two bolts, and the steering wheel simultaneously changed to the other steering column pivot. The tractor’s ground clearance could be adjusted from 33 to 53 cm, which also changed the length. The DT-14 cost about 15% less in Finland than the Pikku-Valmet. About 400 units were sold there. Based on testing by Vakola, it was ordered banned from sales, but by then production had already ended.

The DT-20, introduced in 1958, was a further developed model with a power output of 18 hp at 1600 rpm and, for short durations, 20 hp at 1800 rpm. Electric start, glow plugs, and foot throttle were standard. The hydraulics were renewed and more powerful than before. In addition to steering brake pedals, there was a separate combined brake pedal. Nearly 250,000 units of the DT-20 were produced.
