Introduction to the 9F-70 Forage Grinder for Tractor
The 9F-70 Forage Grinder for Tractor represents a robust solution in agricultural processing equipment, designed to efficiently pulverize forage materials for livestock feed. Manufactured by Netherlands Square Baler Co., Ltd., this forage grinder features a stationary operation structural form, driven by stationary power from a diesel engine with a rated power of 191 kW. Its welded shell manufacturing method ensures durability, while the hammer mill type rotor structure, with 64 hammers and hammer sets, facilitates high-efficiency grinding. The rotor disc diameter of 450 mm and working diameter of 700 mm contribute to its capacity to handle substantial volumes.
The grinding chamber width of 1100 mm allows for ample material intake, and the overall dimensions of 7700×2600×2900 mm make it suitable for farmyard setups. With a PTO speed of 1800 r/min and wheelbase of 2200 mm, this agricultural crusher achieves productivity of 5-20 t/h, weighing 5500 kg in total. The tub feeding system enhances user convenience, enabling easy loading of hay, straw, or silage. As a hay grinder, it excels in breaking down fibrous materials into fine particles, improving digestibility for animals.

Netherlands Square Baler Co., Ltd. emphasizes precision in design, incorporating features that minimize downtime and maximize output. For instance, the hammer configuration allows for replaceable parts, extending machine life. In one case, a dairy farm in the Midwest USA utilized this best forage grinder for livestock to process 15 tons of alfalfa daily, resulting in 20% improved feed conversion rates due to finer particle size. This demonstrates its reliability in high-volume operations.
Key Features and Functionality of the Forage Grinder
This forage grinder’s drive type and power type, relying on a powerful diesel engine, provide consistent performance without dependency on electrical grids, ideal for remote agricultural areas. The structural form supports stationary installation, ensuring stability during operation. Functionality centers on the rotor’s hammer mill design, where 64 hammers pulverize material through high-speed rotation, achieving uniform grind sizes. The rotor dimensions optimize energy transfer, reducing power consumption while maintaining high throughput.
Product details include a welded shell for structural integrity, resistant to wear from abrasive forages. The feeding method via tub system prevents blockages, allowing continuous operation. For compatible tractor models, this high-efficiency hay grinder for farms pairs with heavy-duty units like John Deere 6R Series, Case IH Puma, or Massey Ferguson 6700 Series, which offer 150-200 kW power. Hydraulic requirements of 2-4 outlets at 2500-3500 PSI enable seamless integration for auxiliary functions like lifting.
Tire sizes of 16.9-28 rear and 12.4-24 front enhance mobility if repositioning is needed, while the 12V/24V DC electrical system connects directly to tractors. Warranty of 2 years for structural components and 1 year for others underscores quality. In a case from a European grain farm, the machine processed corn stalks into mulch, increasing soil fertility and yielding 10% higher crop returns the following season.
Application Areas and Product Qualifications

The 9F-70 excels in livestock feed preparation, grinding hay into palatable forms for cattle, sheep, and horses. In crop residue management, it converts straw into bedding or biofuel feedstock. Application in dairy farming involves silage processing, where fine grinding improves fermentation. Qualifications include adherence to international safety standards, with robust testing for vibration and noise levels. As a durable straw chopper for tractors, it holds certifications for emissions compliance, ensuring eco-friendly operation.
Product details extend to customizable hammer configurations for different material hardness. The productivity range of 5-20 t/h accommodates small to medium farms, with total weight distributing evenly for stability. In a South American operation, this precision feed crusher for dairy farms handled soybean residues, reducing waste by 25% and enhancing animal health through better nutrition absorption.
Netherlands Square Baler Co., Ltd. integrates this grinder with other products like round hay balers for complete forage chains. Qualifications feature patented hammer designs for longevity. A case in Asian rice fields saw the machine grinding paddy straw for mushroom cultivation, boosting secondary income by 15% through efficient residue utilization.
