Harrow tooth

The spring tooth is designed for pre-emergence tillage. Application: spring harrow; cultivators; seeding machinery; pickers; rotary rakes; combines; wheel-finger rakes and blowers.

Harrow Tooth Advantage

Heavy-duty steel processing technology ensures a long period of preservation of the original tooth shape and elasticity, even under intense cyclic loads.

To increase wear resistance and fatigue strength, the harrow tooth is processed with a shot. The technology increases tooth life by 30% by creating a hardened surface layer.

Durability and economy
The teeth for harrows are made of special spring steel 60C2A, as well as analogues of EN, which guarantees a high service life and resistance to shock loads and abrasive wear. This will reduce your costs for spare parts and equipment downtime.
Quality and elasticity
The advanced heat treatment technology of the workpiece preserves the properties and characteristics of the heavy-duty spring wire. This provides two key advantages of the products: the preservation of elasticity and shape, the tooth, and the rack resist residual deformation longer and retain their springy properties throughout their entire service life. The products retain their elasticity, and the risks of cracks and fractures in the most stressed areas, curls and bends are reduced. This increases the life of the part under shock loads and abrasive wear.
Hardness and permeability
Combined heat treatment provides different hardness of the spring parts, increasing overall wear resistance and efficiency by 1.5 times. Working part 48...52 HRc - high hardness guarantees maximum resistance to abrasive wear. Spring part 42...46 HRc- optimal hardness, high elasticity, high technology provides exceptional strength and efficiency, 100% treatment of heavy soil.
The benefits of ownership
The shotblasting of the entire surface creates a hardened layer that increases fatigue strength and resistance to abrasive wear. Therefore, the service life of the tooth, especially when working in conditions of high vibration and abrasive wear, increases by 30%. This reduces operating costs and the frequency of replacement parts.
Quality control in accordance with ISO 9001 standards.

The results of the resource tests confirmed the high margin of fatigue strength of the harrow tooth - all samples withstood the full volume of cyclic loads without breaking while maintaining their shape.
The parameters are checked:
• control of geometric parameters of products
• surface quality control
• measurements of thickness, application quality, adhesion -coatings for each batch selectively, at least 10%
• marking and completeness control.

Harrow tooth classification

The harrow tooth / agitator / rack is a torsion spring of complex shape made of alloy steel with high elasticity and hardness.

Types of torsion springs for the agro-industrial complex:
• A spring tooth is the main type of working organ of a harrow for loosening soil
• A harrow tooth is the main type of working organ of a harrow for loosening soil.
• A tooth for a rake - trowel is a working organ for processing mowing.
• The multi-injector rack is a supporting element for the fertilizer application system.
