When growing sunflower with a varying row spacing and a rugged relief of harvested fields, a good adjustment of harvesting units is needed. The universal Sun Stream series rowless header is designed to maximize the combine's performance in sunflower harvesting. They enable harvesting sunflower regardless of the row spacing, direction of sowing and variety.

Due to their low weight, while operating the same coverage as the row header, they guarantee a reduction in fuel consumption. Simple and robust design of the header guarantees long-term, reliable operation and allows use it for harvesting sunflower in any region where this crop is cultivated.

For harvesting confectionery seeds, as well as operations on weedy fields, designs with a pulling shaft and elongated dividers are offered.

Key features

Great capabilities

Customer-specific adjustable or non-adjustable lifters allow harvesting sunflowers of oil-bearing or confectionery varieties, considering maximum biological features of varieties and hybrids, as well as expanding the range of header applications
Adapting to biological features
The ability to adjust the angle of the lifters and the header itself (at the connection to the feeder house) allows working on fields with a slope up to 8° in any direction without losing the process quality
Working on slopes

Effective operation

A special modification with elongated dividers was developed to exclude losses and clogging (especially for confectionery varieties). They have a larger clearance, and the pulling shaft located under the knife bar. This design solution allows you to cut the plants at the base of the head, preventing weeds and stems from entering the hopper
Pulling shaft
The use of a shredder allows leaving small particles of frondiferous mass on the field, which accelerates their decomposition and reduces the cost of subsequent tillage
Simple design: only one gearbox and a minimal number of drives reduce the overall weight of rowless headers. This allows to aggregate wide-cut adapters with lesser-class harvesters and maximize their workload
Maximum harvester load

Perfection of mechanisms

During harvesting, the header feeds the threshing and separating mechanical control system of the harvester with heads with the minimum length of stalk residue. This relieves the harvester cleaning system and increases the cleanliness of the hopper grain
Clean threshing
The header is equipped with a Schumacher cutter bar with replaceable knives, which ensures an effective cutting even in wet harvesting conditions. Knife sections are easily replaced without dismantling the entire cutter bar.
Schumacher cutter bar
The reel is equipped with toothed combs featuring pulling fingers that speed up the feeding of the crop to the header auger. The pulling fingers are height-adjustable, which prevents the crop from hanging on the lifters and ensures uniform feeding
Free from clogging
