Rostselmash has developed a new version of its hybrid-type seeding complex. It incorporates the manufacturer's proprietary solutions. They include a high-strength frame, a pneumatic grain tank, other key assemblies, seeding control software and a dosing system.
"Rostselmash creates equipment that meets the most stringent requirements inherent in modern agricultural technologies, relying primarily on our own engineering solutions and manufacturing capabilities. I am confident that the new seeding complex will be a reliable partner for our farmers," said Alexander Vinogradov, CEO of Rostselmash.
At present, the Rostselmash seeding complex has successfully completed the bench-testing phase and is undergoing field trials, seeding spring barley in tandem with another new product from the company – the Rostselmash 3580 tractor. It is scheduled for delivery to a major agricultural company for field trials on winter crops in autumn 2026. A production decision will be made based on the results.
Like the previous versions of the SH series seeding complexes, the new complex, with a cutting width of 10.2 m, simultaneously performs pre-sowing tillage and in-soil application of mineral fertilizers. The sweeps in the cultivator section cut weeds, loosen the soil, and create a level, compacted seedbed for seed placement. Mineral fertilizers are applied into the space under the sweeps below the openers, while seed is delivered into the soil via double-disc openers. The possibility of separate placement of seeds and fertilizers to different depths with different seeding rates has a positive effect on the development of plants.
Among the key advantages, is an upgraded dosing system powered by an electric motor and manufactured domestically. This system helps to get maximum seeding rate accuracy with an error of 2%. The new model also features a unique downforce system that increases pressure on each opener of the cultivation section to 120 kgf, along with an updated control system. These improvements guarantee uniform working depth within a range of 2 to 12 cm.
The developers have also focused on the efficiency of the seeding complex when paired with self-propelled machinery. For instance, the integration of an axial-piston motor has not only enhanced the unit's operational reliability but also reduced the requirements for the performance of tractor's hydraulic system.
Changes have also been made to the machine's transportability on public roads. Due to a compact five-section cultivator frame, the overall height of the unit in transport position has been reduced from 5.2 m to 3.9 m.
The new-generation pneumatic grain tank differs from metal tanks, which are prone to corrosion when used with mineral fertilizers, and features a longer service life. Its plastic compartments are manufactured at the Rostselmash site using rotational molding of thermoplastic polymers.
