One of the leading manufacturers of agricultural machinery in our country is. In fact, this is a group of companies that have production lines not only in Russia, but also in Ukraine, Kazakhstan, the USA and Canada. The main specialization of the company is the production of grain and forage harvesters. Currently, the company produces about 18 categories of special equipment, which gives a total of up to 100 different models. Rostselmash has firmly established itself in the top five world leaders in the production of grain harvesting equipment, confidently competing with such giants in this area as the USA and Canada.

In this article, we will talk about the RSM 1401 forage harvester model, which is ideal for working in large areas where it is impossible to do without the use of high-performance equipment. The nominal performance indicators of the RSM 1401 combine allow harvesting up to 140 tons of feed per unit of time, which is higher than that of its predecessor DON 680M; accordingly, even large agro-industrial holdings will be provided with feed in the shortest possible time. At the same time, the equipment is characterized by ease of operation, ease of use and high build quality. Let's look at the technical characteristics of this amazing machine.

History of creation

Let's take a short excursion into the past and look at the history of the development of the Rostselmash enterprise. The construction of the plant's production workshops was completed in 1929, and the company immediately began designing grain harvesting equipment. The first combine harvester was the “Kolkhoz”, which successfully passed field tests in 1930. A year later, the “Stalinets” combine was designed, which amazed spectators at an industrial exhibition in Paris. A series of these combines was produced for about 20 years. The last vehicle in the model range was the Stalinets-6, launched into mass production in 1947. By the way, the designers of this model became laureates of the Stalin Prize.

In 1955, the technically outdated Stalinists were replaced by a fundamentally new machine, the RSM-8. The distinctive features of this model are a wide-area header and a beater drum. In addition, the throughput of the threshing device was increased. The production of this combine continued until 1958, then the enterprise switched to producing self-propelled grain harvesters, the SK-3 series.

• The modern history of the enterprise is also marked by the development and production of new combines:
• 2004 – VECTOR series. This modification differs in that the power plant is located behind the grain bin.
• 2007 – ACROS 530. Thanks to its design features, the model was 15% ahead of its classmates in terms of performance.
• 2009 – TORUM 740. This is an innovative rotary machine of class 7 performance.

In 2009, simultaneously with the development of TORUM, work was carried out on the RSM 1401 forage harvesting machine and the KSU-1 self-propelled universal mower. The RSM 1401 combine harvester differs from its classmates in its well-thought-out layout, which allows it to work with minimal resource consumption in any weather conditions. The operating speed of the equipment is 18 km/h, this does not affect the cleanliness of the cut and the quality of grinding of the plant mass.

Technological path

The RSM-1401 combine harvester is distinguished by a well-thought-out and verified layout of all the components of its technological path, which guarantees uniform movement of plant mass along it along an optimal trajectory throughout the entire processing process. This allows you to achieve the best energy intensity of agricultural machinery, as well as create conditions for economical consumption of diesel fuel.

The speed is increasing: each subsequent technological operation is performed by the combine at a higher linear speed than the previous operation. This ensures the stable flow of the entire technological process as a whole, and consequently the production of high-quality silage, grain haylage or haylage.

Design Features

The main criteria when choosing a combine harvester are its power, productivity and versatility. On all counts, RSM 1401 deserves the highest score. The equipment does a good job of harvesting and chopping coarse crops, followed by loading them into trucks. Such indicators cannot be achieved without the use of high-tech components and parts. Let's look at the main elements of the combine in more detail.

Engine. Many combine harvesters produced by Rostselmash are equipped with domestic engines. RSM 1401 was no exception to this rule. The vehicle is equipped with a YaMZ 7511 diesel power plant. This is a turbocharged engine with a V-shaped cylinder arrangement and air cooling. Diesel power is 400 hp. With. Please note that some machines are optionally equipped with MERCEDES 6L engines, increasing the power of the combine to 450 horsepower. The power units are connected to a planetary gearbox and a clutch. Through the gearbox, the necessary power is transmitted to operate the hydraulics and pumping stations of the hydraulic structures. The clutch drives the threshing drum, the additional chopper and the accelerating device. This scheme made it possible to abandon the use of intermediate belt drives.

Feeding and grinding device. The feeding apparatus, which is equipped with RSM 1401, is a four-roller device of increased reliability. The feeding unit provides four speed modes for feeding plant material, which gives an adjustable cutting length (4/7/10/17 mm). The gap between the lower and upper rollers is 24 millimeters, which increases the efficiency of the metal detector. The device has a reverse function, which simplifies the removal of foreign objects caught in the mechanism. The use of a grinding device allows you to reduce the load on the feeding apparatus. A drum with a diameter of 630 mm is installed here. rotating at a speed of 1,200 rpm. The cutting elements of the drum are arranged in a V-shape, which ensures a centralized supply of plant mass. Please note that the chopping device circuit includes a system for automatically sharpening knives.

Adapters. Grain and forage harvesters are useless without the proper attachments. In the case of the RSM 1401 combine, the following adapters are used:

• Front header with a terrain following system and a hinged, balanced part. The width of the header is 5 m. 6/8 row header designed for harvesting agricultural silage crops and corn.
• drum-rake type pick-up
• Useful options. At the customer's request, the RSM 1401 forage harvester can be equipped with a system for introducing preservatives. For this purpose, two five-liter containers with ultraviolet protection are installed. It is possible to install a video surveillance system that provides visual control over the degree of filling of the grain bin. An automated lubrication system is optionally installed, which significantly simplifies the maintenance of the combine.
