OverviewSpeed Flow sunflower headers are rowless harvest headers designed to harvest regardless of sowing direction. Optional roto-cut rotating cutter with a reel shreds stem residues and protects the combine underside. Design solutions keep seed loss down to around 3% and enable operating speeds up to 12 km/h. An under-cutter rotor and hydraulic flap allow work on uneven sunflower fields. Available working widths range from 4.1 m to 13.1 m.
Key features- Rowless design: harvest regardless of row orientation and inter-row spacing.
- Optional roto-cut rotating cutter with reel to shred stems and protect the combine underside.
- Low seed loss: engineering measures achieve seed loss of up to 3%.
- High operating speed: up to 12 km/h with adjustable sunflower head gripper and collection screw conveyor.
- Manually adjustable crop divider platform width to minimize losses with thin-stem varieties (3.5–7 cm clearance).
- Hydraulic flap and under-cutter rotor for uneven-height sunflowers and irregular fields.
- Universal mounting: compatible with most combines via dedicated mounting frame, hydraulic couplings and gearbox reductions.
Roto-cut systemThe optional roto-cut system is mounted on an independent frame with hydraulic adjustment of cutting height from the operator cabin. It uses durable bevel gears and cutters in wear-resistant steel with tungsten carbide coating. Rotor blade tip shredding speed is 25 m/s. A crushing reel behind the shredder protects tyres and accelerates residue decomposition.
Drive and componentsPower to the roto-cut is transmitted via cast-iron bevel gear transmissions and PTO shafts, protected by a central friction clutch to prevent damage from sudden jams. The cutting unit incorporates components from established manufacturers to ensure durability and reliability.
