Sunflower harvesting header Speed FLOW 7.75

with hydraulic adjustmentfor combine harvestersrotary

Overview
PWL SpeedFlow headers are rowless sunflower harvest headers designed to harvest regardless of sowing direction. They can be equipped with an optional roto-cut rotating cutter with a reel that shreds stem residue. Design features deliver low seed loss (up to 3%) and enable high operating speeds (up to 12 km/h). An additional rotor under the cutter bar and a hydraulic flap allow operation on uneven sunflower fields. Machines are available in multiple working widths from 4.1 m to 13.1 m.

Key features

• Rowless design — harvest regardless of row orientation
• Optional roto-cut system for shredding residue and protecting the combine underside
• Adjustable crop divider/platform width (manually adjustable to reduce clearance and minimize losses)
• Hydraulic flap and under-cutter rotor to manage uneven sunflower heights
• Adjustable sunflower head gripper and collection screw conveyor for controlled material flow
• Universal mounting — adaptable to most combines with appropriate frame, hydraulic couplings and gearbox reductions
• High working speed capability (typical 7–10 km/h, up to 12 km/h)

Roto-cut system & residue management
The optional roto-cut is mounted on an independent frame with hydraulic cutting height adjustment from the operator cabin. It uses durable bevel gears and cutters made of wear-resistant steel coated with tungsten carbide. Rotor tip speed: 25 m/s. A crushing reel behind the shredder protects tires and accelerates decomposition of residues.

Drive & protection
Power transmission for the roto-cut uses cast-iron bevel gearboxes and PTO shafts to ensure low maintenance and long life. A central friction clutch protects the machine from damage caused by sudden jams, allowing higher working speeds.

Operation & control
Cutting height for the roto-cut and the hydraulic flap are adjustable from the operator's cabin. A cutting height indicator on the header is visible to the operator for precise control.
