Belarus

Based on the Belarus 3022, in 2009 a more powerful model 3522 was introduced, equipped with a 7.1-liter Deutz engine. The hydraulics with an adjustable displacement pump were purchased from Rexroth. The transmission was mechanical 24+12 (with creeping gears 36+24) and featured a 6-speed quick shift. The clutch was a dry 2-plate type.

In 2015, the only versions meeting Western requirements were the Stage IIIb-compliant 3522.5, which had a Deutz engine, and the 3522.6 equipped with a Cummins engine.

In 2016, a 466-horsepower prototype Belarus 4522 was introduced, which entered the sales program in 2019. At that time, its engine was a 12.5-liter Caterpillar with a power output of 431 hp.

Belarus 3522-4522

Belarus introduced models meeting different emission requirements as regulations tightened, and all the old versions remained in the lineup for markets that were satisfied with them. The novelty of the 4-series was the common rail injection system, which allowed meeting Stage IIIA requirements. The 5-series introduced in 2013 featured urea injection, achieving Stage IIIb/Tier 4i levels. In 2015, the 6-series came out, equipped with an oxidation catalyst and emissions compliant with Stage IV/Tier 4. It is noteworthy that these requirements were met with their own engines, although at the lower emission levels, engines purchased externally were initially needed.

The 150-210 horsepower Belarus tractors did not gain much popularity, at least in Europe. Their technology was quite simple for their size class. The transmission was 16+8 or 24+12 without creep gears. The lifting capacity was 6.5 tons, and the power lift was standard.

In autumn 2019, the 1523.6 was introduced with a new appearance.

Belarus 1523.5-2022.6

In 1999, Belarus took a bold step towards larger tractors with the introduction of the 155-horsepower 1522. The 7.12-liter six-cylinder engine was fundamentally the same as the one previously introduced in the 1221 model. Similarly, the 16+8 transmission without a creeper gear was derived from the smaller model. The angular, 1990s-style design was new, and no other models with a similar style were introduced. In the 1523, introduced in 2004, the design shifted to a rounder, streamlined style, following the trend of smaller new models. The 1523 featured the same curved-glass cab as the 1222.

The lifting capacity was 7000 kg, appropriate for the tractor's size, and a Bosch electric lift was typically standard equipment. Three hydraulic valves were standard. The standard tires were relatively small for the size of the tractor.

In the intermediate-cooled 1523.3, introduced in 2006, the design shifted to a rear end and shorter wheelbase similar to the smaller models. The 1523.4, equipped with a Deutz engine, was also produced with a longer wheelbase.

The 2022 differed in design from the 1522/1523 but had minor technical differences. The engine was either Belarus’s own 7.1-liter or a similarly sized Deutz.

Vladimir Tractor Factory developed a slightly more powerful T-30 based on the T-25 in the mid-1970s. The engine power was increased to 30 horsepower. The transmission also came from the T-25, meaning it featured a directional reverser and crawling gears. In Sweden, this model was sold under the name Belarus 30. The same series also included the 3-cylinder T-45.

In the early 1990s, the T-30 became a tractor with a distinctive appearance. A new feature was independent power and hydrostatic steering. Most of the tractors produced were the T-30A model, which were four-wheel drive versions.

The successors to these models were the sloped-nose VTZ-2032 and VTZ-2048.

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.

The revised Kirovets K-744 R went on sale in 2014, marking Kirovets' return to many Western European markets. The most significant upgrades were made to the hydraulics. The pump was now standard with load-sensing and had a flow rate of 180 liters per minute. The cab roof section and engine hood were redesigned, and the fuel tank was now made of plastic. The noise level inside the cab was reduced to 75 decibels. For the lower-power model equipped with a Western engine, the engine manufacturer was now Cummins. Models with short wheelbases were removed from the lineup. The lifting capacity was specified as 8,500 kg at the lifting point. Based on the next model series, the lifting capacity at the ends of the drawbars was only about five tons. In 2016, an electro-mechanical gearshift and gear automation became available.

For the year 2018, the flagship model of the lineup introduced was the K-743, which replaced the previous K-744 R. The engine was still Mercedes' 10.7-liter, but now met the stage IV final emissions standard. The power had increased to 435 horsepower. The transmission was a new T5 quick-shift automatic. The range shift operated pneumatically. Load-sensing hydraulics were supplied by Bosch Rexroth. There were four hydraulic blocks. The new T400 axle was reported to be 27% stronger than before, and the brakes had been changed to disc brakes. The lifting capacity was now stated as 5500 kg at a standard distance of 610 mm.

The cab was updated to Comfort Plus. The noise level remained at 75 dB. Despite the purchased components, Kirovets stated that 70% of the tractor’s parts were of its own manufacture.

Outside Western Europe, the series also included many other models with YaMZ, Tutaevsky, and Mercedes engines in lower emissions classes. The last two digits of the model number indicated the maximum power. In 2020, a shorter wheelbase K-525 was also introduced, whose 250-horsepower YaMZ engine met the stage IIIa emissions standard.

The Kharkov Tractor Factory had mainly produced crawler tractors, but in 1950, production began there of a small 12 hp wheeled tractor. The engine of the HTZ-7 was a 2-cylinder gasoline engine. The transmission was a 4+4 equipped with a direction reverser. Also exceptional for this size class was a hydraulic lifting device. The HTZ-7 was a so-called "reversible tractor": the seat could be moved to the other side of the vertically positioned steering shaft by loosening two bolts, and the steering wheel could simultaneously be attached to another pin on the steering shaft. The tractor was started with a crank. In addition to magneto ignition, the only electrical equipment—namely the lights—received power from a dynamo. During a period of six years, about 48,000 units of the HTZ-7 were manufactured. Only a few were imported to Finland; however, its diesel-powered successor, the DT-14, became well known here as well.
