SHELBOURNE (UK)
The company was founded in 1972 when Keith Shelbourne acquired the assets of Reynolds Engineering and formed Shelbourne Reynolds Engineering Ltd. For over 45 years, the company has been developing and manufacturing innovative agricultural machinery and attachments, exporting to more than 40 countries worldwide.
The company's main focus has always been and remains the production of stripping headers with various cutting widths.
ADVANTAGES OF SHELBOURNE STRIPPER HEADERS
HIGH CLEANING EFFICIENCY
Shelbourne stripper headers are ideal for efficiently harvesting fields with heavy weed loads, lodged crops, and plants damaged by hail, for example. The header's rotor rotates from the bottom up (in the opposite direction to the combine's rotation), allowing the stripper fingers to quickly and efficiently lift lodged heads and direct them into the auger chute, leaving stubble in the field. The clever design of the stripper fingers allows green weeds to remain in the field, reducing the load on the combine and increasing its productivity and harvesting speed.
FUEL ECONOMY
Traditional harvesting requires a significant amount of energy to cut plant stems, transport them, separate them, thresh them, and operate the chopper, which consequently requires significant fuel consumption. Stripping harvesting requires significantly less energy, significantly reducing fuel consumption. Furthermore, using a stripper header significantly reduces combine wear and extends its service life.
MINIMAL GRAIN DAMAGE
Due to the fact that the threshing of the majority of the grain occurs in the header itself, the combine's threshing system can operate significantly slower and, accordingly, less aggressively towards the harvested crop.
OPPORTUNITY TO START CLEANING EARLIER
A stripper header allows harvesting to begin 1-2 weeks earlier than usual, with grain moisture levels up to 35%. Drying wet grain at the beginning of the harvest is significantly easier and less expensive than drying it at the end.
CONSERVING MOISTURE IN THE SOIL
Strip harvesting leaves a large amount of stubble in the field, which effectively protects the soil from sunlight, allows moisture to accumulate, retains snow, and prevents erosion.
SIMPLE, ROBUST AND THOUGHT-OUT DESIGN
Shelbourne headers are made of high-quality, wear-resistant components, ensuring high durability and years of trouble-free operation. The header rotors consist of eight rows of stripper fingers made of ultra-strong stainless steel. The absence of quickly wearing components and parts significantly reduces operating costs.
FEATURES AND ADVANTAGES OF THE COMBO CLEANING TECHNOLOGY
-
Increase in combine productivity by 30-50% and a significant increase in harvesting speed
The average grain harvested by a traditional header consists of one part grain and one and a half parts straw, while the harvested grain by a stripper header, under identical conditions, consists of one part grain and only a quarter straw. Reducing the grain mass entering the combine by half due to the reduced amount of straw in the grain pile results in the combine's threshing system operating at an underload, creating a reserve in its throughput capacity. This allows the combine to move 1.5-2 times faster during harvesting than a traditional header.
-
Reduced fuel consumption by an average of 40%
If we assume that a combine harvester, when the threshing apparatus is fully loaded with grain mass, consumes the same power regardless of the ratio of grain and straw in it (in fact, the more grain in the grain mass, the less power is consumed), then fuel consumption will be less, as much as there is more grain in the grain mass entering the combine, that is, 1.5-2 times.
-
Extending harvesting time by working in a wider range of crop moisture levels
The upper moisture limit is limited only by the biological maturity of the crop, so stripper headers harvest grain well with moisture content as low as 35%. The lower moisture limit is limited by the equilibrium moisture content of grain storage, which is 12-15%. At lower moisture content, the grain-to-ear connection weakens, and the mechanical action of the header on the stalk can cause additional grain loss. Despite this, by starting harvesting on average 10-12 days earlier, the overall harvesting season with a stripper header is longer than with traditional headers.

The stripper header is an ideal component in a no-till and minimum-till system.
Threshing standing crops has proven effective not only during harvesting but also in creating favorable conditions for higher yields when combined with disc seeding (no-till). When sowing in the spring, it's best to leave the stubble intact. This helps conserve energy and improve water retention. Stubble protects the soil from solar heating and moisture evaporation. Moisture retention occurs by trapping snow in the tall stubble. This technique is crucial in arid regions.

High-quality harvesting of lodged crops
The rotor of Shelbourne stripper headers rotates from the bottom up, which helps to easily lift lodged crops for stripping.
