Agriculture Machinery Parts Disc Plough/Plow Blade Disc Harrow Blade

Overview

In modern agriculture, the efficiency of soil preparation directly impacts crop yield and resource utilization. Our Agriculture Machinery Parts—including Disc Plough Blades and Disc Harrow Blades—are designed to excel in primary and secondary tillage, delivering consistent performance across diverse soil types and farming conditions.

Manufactured using advanced casting and heat treatment processes, these blades combine high-strength alloy steel with precision-engineered geometries to cut, break, and level soil with minimal resistance and maximum durability.

Starting with premium-grade steel alloys (such as 65Mn or boron-treated steels), we use either sand casting or precision forging to form the blade’s foundational structure, ensuring uniform material density and structural integrity. The blades undergo a rigorous heat treatment cycle—quenching and tempering—to achieve a balance of hardness (HRC 48-55) and toughness, critical for resisting wear from stones, roots, and abrasive soil particles. Each blade is then precision-ground to optimize cutting angles (typically 35-45 degrees for plough blades and 20-30 degrees for harrow blades), ensuring smooth soil penetration and efficient residue incorporation.

Features

Adaptive Soil Engagement

The concave design of disc plough blades creates a self-sharpening effect as they rotate, maintaining cutting efficiency even after prolonged use. Disc harrow blades, with their shallower curvature, excel at breaking up clods and incorporating organic matter into the topsoil. Both types feature thickened edges and reinforced hubs to withstand impacts from hidden rocks or tree roots, reducing the risk of chipping or bending.

Material Excellence

Our blades are made from high-carbon, high-manganese steel alloys formulated to resist abrasion and fatigue. The addition of alloying elements like chromium and molybdenum enhances corrosion resistance in wet, acidic soils, while the heat-treated surface forms a wear-resistant layer that outlasts standard carbon steel blades by 30-50%.

Precision Geometry

Computer-aided design (CAD) ensures optimal blade diameter (600-1200mm for ploughs, 400-800mm for harrows), thickness (8-15mm), and spacing to match the power output of tractors and the specific tillage depth required. The balanced weight distribution minimizes vibration, reducing stress on the machinery’s drivetrain and improving operator comfort.

Easy Maintenance and Replacement

Standardized mounting interfaces (bolt-on or quick-release hubs) allow for fast installation and removal, simplifying blade replacement in the field. Many models feature reversible designs, enabling users to flip the blade when one side is worn, effectively doubling service life before replacement is needed.

Environmental Sustainability

By promoting efficient soil aeration and moisture retention, our blades support sustainable farming practices. The precise cutting action reduces fuel consumption by up to 20% compared to outdated tillage tools, while the durable construction minimizes waste from frequent part replacements, aligning with global goals for resource-efficient agriculture.

Applications

Secondary Tillage (Disc Harrow Blades)

Following primary tillage, disc harrow blades refine the seedbed by smoothing clods, removing weeds, and incorporating fertilizers or manure into the topsoil. Their lighter weight and shallower penetration make them suitable for sandy or loamy soils, as well as for post-planting cultivation to control weeds without damaging young crops.

Specialized Applications

No-Till and Conservation Tillage: Modified blades with wider spacing and anti-clogging profiles are used in no-till systems to minimize soil disturbance while cutting through crop stubble, promoting water retention and reducing erosion.

Orchard and Vineyard Management: Narrow-profile blades navigate between tree rows, tilling the soil without damaging roots, ideal for maintaining healthy root zones in perennial cropping systems.

Municipal and Landscaping: Smaller disc blades are used in garden tractors and compact loaders for lawn preparation, soil amendment, and turf renovation, delivering professional-grade results for residential and commercial landscapes.

Global Farming Environments

From the arid plains of Australia to the wet rice paddies of Southeast Asia, our blades are adapted to regional challenges:

High-Impact Soils (e.g., rocky fields in Spain): Reinforced blade tips and thicker hub sections prevent damage from embedded stones.

Acidic/Peat Soils (e.g., Netherlands wetlands): Corrosion-resistant coatings protect against soil-borne chemicals and moisture.

Heavy Clay Soils (e.g., Midwest USA): Aggressive concave angles ensure continuous soil flow, preventing mud buildup and maintaining cutting speed.

Agriculture Machinery Parts Disc Plough/Plow Blade Disc Harrow Blade
A harrow disc is a harrow whose cutting edges are a row of concave metal discs, which may be scalloped, set at an oblique angle. It is an agricultural implement that is used to till the soil where crops are to be planted. It is also used to chop up unwanted weeds or crop remainders.
