Rostselmash T500: Stability and Performance Across Any Agricultural Background

Harvesting campaigns under sharply continental climate conditions require harvesters capable of operating across fields with varying yields, in weed-infested and wet backgrounds, and handling high-awned barley varieties or high-straw wheat without losing momentum. The Rostselmash T500 class 6 twin-drum combine is specifically designed for such conditions, delivering a capacity of up to 30 t/h and processing over 1,300 hectares per season. The range of harvested crops extends beyond grains to include pulses, oilseeds, groats, and row crops such as lentils, flax, sunflowers, and corn.

The Tetra Processor twin-drum threshing system, featuring an 800 mm threshing drum and a 750 mm separator, ensures delicate grain extraction without cracking on crops with high awn and straw content. The total threshing and separation area of 8.3 m² maintains high throughput while handling mass of varying moisture levels gently. Electronic concave clearance adjustment adapts the machine to current conditions without stopping. On waterlogged and weak soils, the combine maintains mobility thanks to a 500 mm ground clearance and optional all-wheel drive, paired with a hydrostatic transmission.

A 360 hp YaMZ-537 6-cylinder engine provides sufficient torque for working with wide-span headers at any harvesting speed. The 10,000-liter moisture-protected grain tank is equipped with vibration agitators, allowing the unloading of grain with up to 35% moisture content without delays at a rate of 120 l/s, emptying the tank in under two minutes. An 850-liter fuel tank ensures operation without refueling for nearly two full shifts. A dual-stage cleaning system with an area of 5.85 m² and 4D longitudinal slope compensation minimizes losses.

The versatility of the T500 is proven by practical application on Kazakh farms. At Bolashak Tabys LLP in the North Kazakhstan region, the combine operated through the season on lentils, flax, barley, and wheat, achieving a productivity 1.5 times higher than previous machinery while receiving top marks for fuel efficiency. At Golovkin and Co. LLP, the T500 was used for oilseed harvesting, with management noting stable performance and virtually zero losses in difficult areas.

The relevance of the model to the market is reinforced by its production at the Kazrost Engineering plant in Kokshetau. Localizing assembly shortens delivery logistics and provides farms with prompt regional service support. This technological versatility enables agricultural enterprises to flexibly respond to changing crop structures and market conditions without purchasing highly specialized machinery.
