9ZR Series Chaff Cutter — Complete Assembly
The fully assembled straw cutter machine features a compact footprint, integrated feed hopper, heavy-duty frame, and rear discharge outlet. Every component is precision-aligned at our factory for optimal cutting performance.
Core ComponentsPrecision-engineered parts that define quality
9CrSi Alloy Steel Chaff Cutter Blade
Forged from premium 9CrSi alloy steel with heat-treated edge hardening. Delivers clean, precise cuts with exceptional wear resistance, maintaining sharpness through thousands of hours of operation.
Laser-Cut Integrated Kneading Blade Disc + Hammer Blade
One-piece laser-cut construction eliminates assembly gaps and vibration. The integrated hammer blade system kneads stalks into soft, digestible fibers — improving feed palatability and livestock intake rates.
Pure Copper Core Motor
100% pure copper windings deliver superior conductivity, lower heat generation, and longer service life compared to aluminum-wound alternatives. Provides consistent power output under heavy loads with reduced energy consumption.
Quenched Forged Gears
Forged from high-carbon steel and quenched for maximum surface hardness. The precision-machined teeth ensure smooth power transmission with minimal wear, extending the gearbox service life significantly.
ApplicationReal-world usage across crops and settings
Applicable Crops
Corn stalks, wheat straw, rice straw, sorghum, alfalfa, sweet potato vines, peanut vines, and cotton stalks.
Cutting Effect
Uniform cut length with soft, kneaded texture. Improved palatability leads to better feed intake and digestion for livestock.
Gear Shift Positions
Easy gear shift lever lets operators select cutting length from 10mm to 30mm. Clear position markers for quick adjustment.
