Core Functional Advantages
Elastic curvature lifts lodged crops close to the ground, guiding straw to the cutter, reducing missed cutting and grain loss.
Double-torsion spring allows automatic retreat when encountering stones or clods, preventing tine breakage and header damage.
Even rebound and stable force ensure continuous, uniform pushing of straw into the auger — no jamming.
From economical carbon steel to food-grade stainless steel, all specifications available for different budgets and environments.
Supports galvanizing, powder coating, and electrophoretic coating for dry, humid, and coastal conditions.
Full range of wire diameters and lengths, compatible with most combine harvesters — direct replacement.

RH / LH Structural Design
RH (Right-Hand) — Main Universal Type
Force principle: Right-hand wound spring; torque tightens the coil, maintaining stable spring force.
Primary use: Over 90% of lifting and guiding operations — central area of the reel.
Application: All conventional harvesting conditions. Main model with bulk stock.
LH (Left-Hand) — End-Position Dedicated
Force principle: Left-hand wound spring; counteracts centrifugal outward tension at reel ends.
Primary use: Only used at the left and right end positions of the reel — small quantity per machine.
Application: Essential for high-speed, large-area harvesting to prevent end tine detachment.
