Product Advantage
The World Combine Harvester Blade is a premium cutting component designed for optimal performance in modern combine harvesters. This combine harvester blade features a sharp, durable design that delivers clean, efficient cuts across a range of crops, ensuring minimal crop loss and maximum harvesting productivity. As a critical harvester cutting part, it is engineered to fit world-class harvester models, making it a reliable choice for agricultural operations worldwide.

A cutting gap is formed between the moving blade and the stationary blade (fixed blade), and when the crop ears and straw pass by, the blade moves back and forth to cut the crop. | Blade protectors/blade presses and other accessories are responsible for supporting, positioning, and protecting the blades, while ensuring the accuracy of cutting gaps and preventing blade jumping or deformation. |
Technical Parameters
Our harvester cutting blade is crafted from high-strength, wear-resistant steel, ensuring longevity even in continuous, heavy-duty use. The blade’s precision design includes a sharp cutting edge that maintains sharpness over time, reducing the need for frequent sharpening or replacement. Measuring with a slim yet robust profile, it balances cutting efficiency with structural integrity, allowing for smooth back-and-forth movement in the cutting section. The blade is engineered to work in harmony with fixed blades, pressure blades, and blade guards, forming precise cutting gaps that ensure clean, neat incisions. It features compatibility with the cutting systems of World combine harvesters and related cutting equipment, with a design that prevents jumping or deformation during operation. Each blade undergoes rigorous quality control to meet strict agricultural equipment standards, ensuring consistent performance in diverse harvesting conditions.

Product Uses
Crop-Specific Performance
Perfectly suited for rice, wheat, soybean, corn stalks, barley, oats, and forage grasses. Whether you're running a full-scale grain operation or managing mixed crop harvesting, this blade offers consistently sharp, vibration-free cutting.
Compatible Harvester Types
Engineered as a direct fit for major combine harvesters, reaper binders, forage harvesters, and mower-conditioners. It easily replaces worn blades on popular brands like New Holland, , and LOVOL.
Tough Field Conditions
Treated with anti-rust finishes and hardened to HRC 48-58, this blade is built for heavy dew mornings, muddy rice paddies, dry dusty fields, and long storage periods between seasons. It resists edge rolling and breakage even when encountering occasional hidden stones or dense stalk clusters.
Product Operate Guide
Before any work, shut off the engine, remove the key, and engage all safety locks.
Wear heavy-duty gloves – the cutting edges are extremely sharp.
Support the header/cutter bar securely to prevent it from dropping during blade replacement.
Remove the old blades
Use a proper spanner or impact wrench to loosen the bolts/nuts holding each knife section to the cutter bar.
Slide out the worn blade sections. Note the orientation of the serrated edge (teeth facing the crop side).
Clean the cutter bar surface
Remove rust, dirt, and old crop residue from the bar. A clean mounting surface ensures the new blade sits perfectly flat and prevents premature loosening.
Align the new W2.0-01-01-03G-03-05 blade
Position the blade so the serrated edges face the direction of feed (toward the standing crop).
Align bolt holes with the cutter bar holes. If you have both standard and countersunk bolts, ensure the bolt heads will not hit the guards.
4.Bolt tightening procedure
Insert bolts and thread nuts by hand first.
Tighten gradually in a cross pattern to the manufacturer’s recommended torque (typically 30-40 N·m for M8 bolts, but always verify for your bar).
Critical: Use thread-locking compound or spring washers if originally equipped. Check bolt tightness after the first 2 hours of operation and then daily.
5.Check knife-to-guard clearance
With all blades installed, manually move the knife to check that each blade section moves freely between the guard fingers without rubbing or catching.
Adjust any guard alignment if necessary. The blade should have slight vertical play but not excessive gap.
Blade Hold-Down Clips: Adjust hold-down clips so they guide the blade sections without excessive friction (approx. 0.2–0.5 mm gap). Too tight causes overheating and rapid wear; too loose leads to poor cutting and stem pulling.
Knife Register: Ensure the knife drive head and pitman arm are in correct timing so the blades fully align with the guards at both ends of the stroke. Misalignment can cause stem bunching and missed stalks.
Cutting Height: Set the header height so the knife cuts the lower to middle part of the crop stem, reducing soil contact and shock loads on the blades.
Rice (wet/dry field): Keep forward speed moderate in muddy conditions. The 65Mn hardened steel resists edge rolling when hitting small stones, but avoid continuous rock contact.
Wheat & Barley: Increase blade speed and support sharp serrations for a clean cut through thick, dry straw.
Soybean & Corn Stalks: Lower the knife slightly if the crop has thick, woody stems. Check hold-down clips more frequently due to higher vibration.
After Each Day: Clear crop debris and mud from the knife bar. Inspect for missing or loose bolts.
Blade Sharpening: The W2.0-01-01-03G-03-05 is factory-sharpened by precision pressing/milling. If re-sharpening becomes necessary, use a blade grinder or flat file along the serration edges. Maintain the original edge angle – do not round the serrations.
End-of-Season Storage: Wash and thoroughly dry the entire cutter bar. Apply a light coat of anti-rust oil (or diesel-oil mixture) to the blades. Store the header in a dry place, preferably covered. The blade's baked enamel/anti-rust finish provides basic protection, but a manual oil layer extends life dramatically.
Replacement Indicator: If the cutting edge shows visible rounding, chips larger than 3 mm, or the harvester starts pulling plants rather than cutting them cleanly, it's time to replace the blade section with a new W2.0-01-01-03G-03-05.
