Large-Scale Dairy Farm • New Zealand • 800+ Cattle Herd
The Challenge
Before implementing our solution, Green Valley Dairy faced the same operational bottlenecks that affect dairy farms worldwide.
Manual feed preparation required 3 full-time workers, consuming 24 man-hours daily just for chaff cutting operations.
Variable cutting lengths led to poor fermentation results and reduced feed nutritional value, impacting milk production.
Existing equipment couldn't keep pace with 15 tons daily feed demand, creating constant operational delays.
Poor cutting efficiency resulted in 18% raw material waste, directly impacting profit margins.
Client Profile
Green Valley Dairy operates one of New Zealand's premier dairy facilities, managing over 800 milking cows with a commitment to sustainable farming practices. Their operation processes mixed forage including grass silage, corn stover, and alfalfa hay, requiring versatile and reliable feed preparation equipment that can handle diverse material types while maintaining consistent quality standards.
Our Solution
9ZP-2.2 Heavy-Duty Chaff Cutter with 22kW diesel engine, selected for high-volume continuous operation capacity.
Dual-blade rotor system with adjustable cutting lengths (3-50mm) to accommodate various forage types and feeding requirements.
Emergency stop systems, protective guards, and automatic shutdown mechanisms exceeding international safety standards.
45-day production and delivery schedule with on-site installation support and comprehensive operator training program.
Technical Excellence
High-carbon alloy steel blades with 40% longer service life compared to standard cutters. Self-sharpening design reduces maintenance downtime and replacement costs.
Patented roller design prevents material buildup during high-moisture silage processing, maintaining consistent throughput even with challenging materials.
Hydraulic adjustment system allows real-time cutting length modification without stopping operation, optimizing feed preparation for different livestock requirements.
Reinforced steel frame with anti-vibration mounting system ensures stable operation during continuous use, reducing structural fatigue and extending equipment lifespan.

Measurable Impact
Processing capacity improved from 10.5T to 15T per day with same labor input
Staff requirements reduced from 3 to 1 operator, saving $68,000 annually
Material wastage dropped from 18% to 3%, improving raw material utilization
Average daily milk production increased by 4.2% due to better feed quality
The chaff cutter from Golden Machinery has transformed our feed preparation operation. What impressed us most wasn't just the equipment quality, but their engineering team's understanding of our specific challenges. The machine handles our varied forage types flawlessly, and the reduction in labor costs paid for the investment in less than 18 months. This is exactly what we needed to scale our operation sustainably.
Problem Solving
Power Supply Limitations: Farm's existing electrical infrastructure couldn't support the required 22kW continuous load during peak operation periods, risking circuit overload and equipment damage.
Switched to diesel-powered configuration with integrated fuel management system. This provided operational independence and actually reduced operating costs by 12% compared to electric power in New Zealand's rural rate structure.
Variable Material Moisture: Seasonal variations in silage moisture content (45%-75%) caused inconsistent cutting performance and required frequent manual adjustments with previous equipment.
Implemented our adaptive feed roller system with pressure-sensing technology that automatically adjusts feed rate based on material resistance, maintaining consistent output quality across moisture ranges.
Operator Training Gap: Farm staff had limited experience with advanced agricultural machinery, creating concerns about proper operation and maintenance procedures.
Developed customized training program with bilingual operation manuals, video tutorials, and dedicated WhatsApp support group. Conducted hands-on training with all shifts to ensure competency and confidence.
Versatile Solutions
Ideal for feedlot operations processing corn stover and grass hay. Handles tougher, drier materials with consistent cutting performance for backgrounding and finishing programs.
Commercial silage operations benefit from high-volume processing capability. Perfect for contractors serving multiple farms with varied forage types and quality requirements.
Smaller cutting lengths (3-15mm) perfect for sheep and goat nutrition requirements. Reduces waste and improves digestibility for small ruminant operations.
Seamless integration with Total Mixed Ration (TMR) preparation lines. Consistent particle size ensures accurate nutrient mixing and optimal feed formulation.
