BL Series Heavy-Duty Disc Harrow

BL Series Heavy-Duty Disc Harrow is an upgraded trailed heavy disc harrow, with maximum working depth up to 230mm. The densely arranged discs deliver finer soil crushing, compatible with 80-150HP tractors. It features strong overall rigidity and stable operation, and is the ideal tillage choice for large farmland that balances soil finishing precision and working efficiency.

BL Series Heavy-Duty Disc Harrow – Full Product Description

The BL Series Heavy-Duty Disc Harrow is a high-precision tillage equipment optimized and upgraded based on classic trailed heavy disc harrows. It offers 4 standard working width options from 2.2m to 3.4m, perfectly compatible with mainstream tractors in 80-150HP power range. It is purpose-built for large-scale farmland scenarios that demand high soil crushing precision, balancing both working efficiency and tillage quality.

High-Density Disc Layout for Ultra-Fine Soil Crushing
It adopts ultra-narrow 230mm disc spacing paired with 660mm high wear-resistant discs. Soil clods are continuously cut multiple times during operation, and the soil fineness is far better than ordinary heavy harrows of the same specification. It stably delivers 180-230mm working depth, even on heavy clay and high straw residue fields, no large clods will remain after operation, and it directly meets the sowing requirements of precision seeding crops without secondary finishing.
Reinforced Heavy-Duty Durable Structure
The whole frame is made of thickened high-strength square steel tubes, the 38mm/42mm thickened disc axle provides maximum rigidity, which will not cause axle deformation or frame shaking even under full load operation. The gross weight is controlled between 1700kg and 2350kg, which avoids extra traction burden on tractors while retaining full structural strength, delivering extremely low failure rate for long-time continuous operation.
Adjustable Angle Adapts to Multiple Working Conditions
The working angle can be freely adjusted between 17° and 23°. Small angle mode focuses on fine soil crushing, while large angle mode delivers deep penetration to break hard soilpan. One single machine can flexibly switch between different operation modes, and meets various demands from shallow stubble breaking to deep tillage.
Stable Trailed Performance & Convenient Transfer
Equipped with standard European-style wide tires, the trailed structure features simple hooking, smooth operation without jamming in fields, excellent stability for long-time connected operation, and high efficiency when moving between different plots. It is highly suitable for medium-sized farms and cash crop planting bases that pursue high-standard tillage quality.

Typical Applications: Precision seedbed preparation for sowing-sensitive crops, soil finishing on heavy clay fields, deep straw-soil mixing on high straw return fields, and standardized connected tillage for medium and large farms.
