Agriculture is a branch of the national economy that is engaged in the cultivation of plants (crop farming) and the breeding of animals (livestock husbandry), and is the leading branch of the Russian agro-industrial complex (AIC). The agro-industrial complex includes industries serving agriculture (agricultural engineering, equipment repair, production of mineral fertilizers, reclamation construction, etc.), industries providing processing, storage, transportation and sale of products. The grain harvester SK-5M-1 “Niva-effect” has been the most common brand of grain harvesting equipment for many years. Thousands of these machines continue to work successfully in the fields, among the grain harvesters available on the market today, demonstrating the best qualities of Rostselmash equipment. Thanks to the ratio of performance, affordable price and low operating costs, quick payback, the Niva combine, the video of which you can also watch on our page, is one of the most affordable solutions for harvesting grain crops. Cabin. Silence and coolness. Initially made in a Spartan spirit, the new cabin will pleasantly surprise you with its comfort. The air conditioning operates in two modes: ventilation and air conditioning, providing pleasant coolness. Increased comfort seat (similar to the Don-1500B), heater, air conditioning, sponge mat, sealed cabin, modern soundproofing material , create the necessary comfort for the efficient operation of the combine operator. Reliability. Confidence in the stable operation of the combine. Fluid connections are tighter and cleaner after replacing solder joints with cutting ring connections. This guarantees reliable tightness during repeated installation and dismantling. Rubber seals have been replaced with fluorine rubber ones - they shrink less and are much more durable. Belts from the German company Optibelt, the reliability of which has been proven by world practice, have been used in all Rostselmash combines since 2001. All elements of the hydraulic system are supplied only from trusted companies, including products from aviation and defense enterprises. The reel rake design has become more rigid and reliable after replacing welded pipes with solid ones. Engine. Economical and unpretentious. The new D-260.1 engine with turbocharging and a built-in heat exchanger has a longer service life and lower fuel consumption. Fully balanced and with more torque reserve, the engine runs smoother even under high loads. The torque reserve increased to 25% allows you to work in the most difficult conditions. Chassis. Smooth ride, increased maneuverability. Drive axle - smooth hydrostatic drive of the drive wheels greatly facilitates control, provides a smooth change in speed, smooth running and good maneuverability. Now you can move at a speed of even 0.1 km/h. Steering wheel axle - the track width of the steering wheel axle is adjusted to the width of the driving wheels. Now, the wheels will follow the trail, which will significantly reduce soil trauma and improve cross-country ability. Service. Simplicity and convenience For the convenience of measuring pressure in the main hydraulic system and the steering hydraulic system, places for connecting a pressure gauge have been introduced. An additional step allows for a convenient transition from the ladder platform to the thresher when servicing the engine and hydraulic units. Stair handrails and rubberized handles, borrowed from the Don-1500B, increased the convenience and safety of crossings. New chopper-spreader In addition to the universal chopper-spreader PUN-5, a new chopper-spreader has been introduced, which has a simple and reliable design and is lighter in weight. The chopper has two operating modes: chopping and spreading straw across the field and laying straw in a windrow. Simplification of the design has significantly increased the reliability and ease of use of the chopper.

Combine harvester Niva SK 5ME 1

Niva combines are known to any Russian farmer, because they are legendary equipment with excellent characteristics and an attractive price. One of the most popular models since the 70s was the Niva SK-5 model, which was considered the best combine harvester during the Soviet era. Today a new modification has been released with improved performance and functionality - Niva SK 5ME 1 or otherwise Niva Effect. The main purpose of the equipment is high-quality harvesting of cereal crops in fields that have a slope of maximum 8 degrees. This is an ideal machine for Russian conditions and fields; it works great in different climates and shows high productivity.

The technical characteristics of the equipment allow it to be used in small and medium-sized fields, which it can handle perfectly. The appearance and design of the combine was remembered by every resident of the Soviet Union, so many remembered this technique as the best means for harvesting, reaping and loading grain.

Technical characteristics of Niva SK 5ME 1

Full operation and greater productivity are ensured by the use of the D-442-54R diesel engine; if desired, you can order a slightly improved engine as an option - D442-55R with electric start. The engine used has received such features as turbocharging and a heat exchanger; fuel injection is faster and more efficient, causing fuel consumption to be noticeably reduced.

The indicated engine power is 155 horsepower, the engine operates in 4-stroke mode and has a fuel consumption of only 162 g/hp. For long-term operation, a large fuel tank with a capacity of 300 liters is installed. Such a motor and properly selected equipment allowed the combine to provide a productivity of 7.2 tons per hour. But the equipment cannot be called compact and light enough, because the Niva SK 5ME 1 has a weight without a header of 6,637 kg, and with a 5-meter header the weight will be 8,087. For sufficient grain collection without stopping, the grain bin has been enlarged, which now totals 3,000 liters. An interesting fact is that it only takes 3 minutes to completely unload the bunker.

Detailed review of Niva SK 5ME 1

Harvesting with a Niva combine is carried out with maximum efficiency; spare parts for the equipment are quite affordable and are on sale. The new Niva Effect received an improved chassis, represented by high wheel clearance. Due to this, soil damage during grain harvesting is minimal. For comfortable movement and smooth running, a hydrostatic transmission is installed.

Depending on the soil, the combine is able to change its speed, which can reach 100 m/hour. Additionally, the engineers decided to increase the track width of the steering wheels, which significantly improved the maneuverability of the combine. The hydraulic system is very efficient and works with most components. Interesting is the pressure control of the hydraulic system, which facilitates the operation of most parts of the combine.

Maximum comfort is provided for the combine operator; the cabin has a modern design with air conditioning, heating, sound insulation and a comfortable driver's seat. The air conditioner works great and is available even in the initial configuration; noise insulation and the absence of dust provide comfortable conditions for long-term work on the combine. The seat is created in the most comfortable position, so the driver will not experience discomfort after several hours of work.

Main advantages

Each part of the Niva SK 5ME 1 combine has its own characteristics and makes this model the best assistant for its owner. The main advantages can be considered:

1. The engine has lower fuel consumption and a long service life;
2. Maintenance is simple and straightforward; in particular, a pressure gauge can be connected to the hydraulics;
3. The chopper for the Niva combine is used with new characteristics; the PUN-5 chopper-spreader is used;
4. The main purpose is direct and separate harvesting of grain crops.
5. Automation allows you to control the loading of the bunker with grain crops, therefore, when overflowing, the doors open and close only when the bunker is empty again;
6. The header is available in widths from 4 to 6 meters.

For work on the field, the combine is equipped with one drum, the drum itself is of the beater type with an installed beater and deck. This makes it possible to achieve a coverage angle of 128 degrees. As befits modern machines, Niva SK 5ME 1 works with a 4-key straw walker.

Please note that if you intend to harvest crops such as rapeseed or corn with a combine, be prepared to purchase certain equipment. For example, a pick-up platform and a chopper-spreader will be mandatory.

A few disadvantages

Unfortunately, any technique of this level has small, but still disadvantages. These include:

• not suitable for fields with heavy, uneven terrain;
• some parts wear out quickly and require replacement;
• Improper maintenance may increase fuel consumption;
• There is no panoramic view in the cabin.

Price Niva SK 5ME 1

The Belarusian Niva Effect combine is offered at a fairly low cost, which is why it is extremely popular in the countries of the former USSR. The current price for a combine is 3,450,000 rubles; you can find used examples of good quality. It will also offer various equipment, for example, a 5-meter wide header will cost 600 thousand.
