Sunflower harvesting header Speed FLOW 6.75

with hydraulic adjustmentfor combine harvestersuniversal

The PWL Speed FLOW rowless sunflower header is engineered to harvest independent of sowing direction, offering low seed loss and high operating speed. Optional roto-cut cutter, additional rotor and hydraulic flap ensure consistent cutting and residue handling on uneven fields while protecting the combine and accelerating residue decomposition.

Key features

• Rowless Speed FLOW design: harvests regardless of sowing/row orientation and inter-row spacing.
• Optional roto-cut rotating cutter with rear reel for shredding stems; cutter rotors reach approx. 25 m/s blade-tip speed.
• Low seed loss: design target up to 3% when operated correctly.
• Adaptation to uneven fields: additional rotor under the cutter bar and hydraulically controlled retractable flap bend and pull heads for consistent cutting.
• Adjustable crop divider platform (3.5–7 cm clearance) to minimise losses with thin-stem varieties.
• Hydraulically adjustable cutting height from the operator cabin; cutting height indicator visible on the header.
• Durable drive and protection: cast-iron bevel gearboxes, PTO shafts and central friction clutch to protect the machine in case of jams.
• Wear-resistant steel blades with tungsten carbide coating (blade coating hardness 60 HRC).
• High working speeds: typical 7–10 km/h; design supports up to 12 km/h.
• Universal mounting: can be fitted to most combines with appropriate mounting frame, hydraulic couplings and gearbox reductions; tilt and frame adjustments available.
