Sunflower harvesting header Speed FLOW 9.75

with hydraulic adjustmentfor combine harvestersyield saving

Overview
PWL SpeedFlow headers are rowless sunflower harvest headers designed to harvest regardless of sowing direction. Models are available in multiple working widths from 4.1 m to approximately 13.1 m. The headers can be fitted with an optional roto-cut rotating cutter and a shredding reel to process stem residue and protect the combine underside. Design features support reduced seed loss and operation on uneven fields.

Key features

• Rowless design: enables harvesting irrespective of row orientation.
• Optional roto-cut system: rotating cutter and reel shred stems to protect the combine underside.
• Low seed loss: reported up to 3% under specified conditions.
• Working speed: text indicates up to 12 km/h; technical table lists a working speed range of 7–10 km/h.
• Under-cutter rotor and hydraulic flap: improve harvesting performance on uneven sunflower stands by bending heads forward and pulling them onto the platforms for cutting under the heads.
• Manually adjustable crop divider platforms to reduce clearance for thin-stem varieties and minimise losses.
• Adjustable sunflower head gripper for gentle transfer of cut heads to the collection screw conveyor.
• Roto-cut specifics: hydraulic cutting-height adjustment from the operator cabin; cutters made from wear-resistant steel with tungsten carbide coating; rotor shredder blade-tip speed ~25 m/s; crushing reel behind shredder protects tires.
• Transmission: cast-iron bevel gearboxes and PTO shafts, with central friction clutch protection against jams.
• Universal mounting: compatible with most combines given appropriate mounting frame, hydraulic connections and gearbox reductions; tilt and frame adjustments for optimal working angle.
• Full in-cabin control: cutting height and hydraulic flap adjustable from the operator cabin; cutting height indicator visible on the header.

Design benefits
Roto-cut accelerates decomposition of crop residues and protects the combine underside. The crushing reel located behind the shredder provides tyre protection. Adjustable platforms combined with the flap/rotor system ensure reliable harvesting quality across uneven-height sunflower stands.
