Corn stalk baling for livestock feeding demands more than volume — it demands clean, finely processed fibre with minimal dust and soil contamination. The 9YF-2200S Dual-Crusher with Negative-Pressure Fan adds a second stage of hammer-claw shredding and an integrated active dust removal system, producing low-impurity, high-density corn stalk bales optimised for direct livestock feeding, silage preparation, or premium straw markets.
Product Overview
This advanced variant of the 9YF-2200S builds on the single-crusher model with two critical upgrades: a second independent hammer-claw crushing stage for more complete fibre breakdown, and a negative-pressure fan system that actively draws dust, fine soil particles, and light chaff away from the material flow before baling. Together, these systems address the two main limitations of single-pass shredding: residual long fibre segments that reduce bale density, and dust and soil particles that reduce feed quality and accelerate wear on internal machine components.
The result is a machine capable of producing corn stalk bales that meet livestock feed quality standards without additional post-baling cleaning or processing. For dairy farms, sheep operations, and large cattle enterprises that use corn stalk bales as direct roughage feed or as silage base material, this output quality is a direct economic benefit: lower feed rejection rates, better fermentation consistency for silage, and reduced veterinary costs associated with dust-related respiratory issues in confined livestock housing.
At 6500 x 2900 x 3360 mm and 2350 kg, this is the largest and most comprehensively equipped machine in the Ever-Power square baler lineup. It requires a minimum of 73.5 kW (100 HP), with 110-130 HP recommended for sustained field operation under full dual-crusher and fan load.
Key Features
Dual-Stage Hammer-Claw Crushing for Maximum Fibre Breakdown
Two sequential hammer-claw crushing stages process material before it reaches the compression chamber. The first stage breaks coarse stalk structure into medium-length segments; the second stage refines these further into short, homogeneous fibres. This two-pass fragmentation is significantly more effective on dense, tall-growing materials — sorghum, late-season corn, heavy-gauge cotton stalk — where single-stage processing leaves fibre segments long enough to resist compression and cause density inconsistency across the bale cross-section. Short, uniform fibres pack more densely, produce more stable bale geometry, and compress with less plunger force — reducing wear on the compression chamber components over time.
Negative-Pressure Fan — Active Dust and Soil Separation
The negative-pressure fan creates a controlled low-pressure zone in the material flow path between the crushing stage and the feed chamber. Fine soil particles, dust, sand, and light chaff — all of which are lifted from the ground along with crop material during pickup — are drawn away from the main material stream by this suction and discharged separately. This active separation process works continuously throughout operation, not as a periodic cleaning cycle, ensuring consistent low-impurity output bale by bale throughout the working day.
The practical outcomes of dust removal are measurable: feed palatability improves when dust and soil content is reduced, silage fermentation quality is more consistent when the starting material is cleaner, and internal machine wear on the plunger face, knotter bill hooks, and twine path guides is reduced when abrasive soil particles are separated before the compression cycle. The fan also improves the operator environment by reducing dust cloud generation in the crop-entry zone of the machine.
Broadest Material Compatibility in the Range
The dual-crusher configuration with active dust separation handles the full spectrum of agricultural residue and forage types processed by any Ever-Power square baler: corn stalks (upright, lodged, or lying), sorghum, cotton stalk, wheat straw, rice straw, alfalfa, dry and fresh grass, and various leguminous forages. The negative-pressure fan further extends the practical material envelope by managing the heavy dust load associated with very dry, brittle crop residues — materials that create dense dust clouds in the pickup zone on conventional machines, triggering frequent cleaning stops and reducing effective operating time.
2200 mm Collection Width at Full Commercial Scale
The 2200 mm working width ensures that the additional processing equipment does not compromise field efficiency. The dual-crusher and fan systems are integrated directly into the main drive train, sharing the PTO power distribution system without reducing forward ground speed capability. Large post-harvest corn areas are covered at the same working pace as a standard-width baler, while delivering significantly superior bale quality at every pass.
Field Applications and Typical Use Cases
The primary crop applications include corn stalks (10-23% moisture), sorghum, cotton stalk, wheat straw, rice straw, alfalfa (17-23% moisture), fresh and dry forage grasses — the widest material range of any Ever-Power square baler. Baled output from this machine serves a range of downstream uses depending on regional agricultural practice and buyer requirements: dairy farm and beef cattle roughage feed (direct bale feeding without secondary processing), silage base material for film-wrapped fermentation, premium straw supply to feed mills and trading operations where impurity specifications apply, and commercial biomass operations with clean-material quality requirements.
Square bales produced by this machine are stackable to uniform heights, making them well suited to container loading, covered warehouse storage, and mechanical handling with telehandlers and front-loaders. The consistent 460 x 360 mm cross-section across all Ever-Power standard models ensures that bale handling and storage infrastructure designed for one model is fully compatible with others in the range.
Operating Conditions
Corn stalks 10-23% moisture; leguminous forage 17-23%. Soil moisture during operation: 12-25%. Maximum slope: 8 degrees. Field surface should be free from large rocks and deep irrigation furrows. Not recommended for extremely high-moisture fresh-cut green material. 110-130 HP tractor strongly recommended for sustained operation in dense, tall corn stalk fields under full dual-crusher and fan load.
How It Works
Step 1 — Dual-Stage Shred and Collect
Two sequential hammer-claw stages fragment corn stalks and hard-stemmed material into short, uniform fibres across the 2200 mm working width.
Step 2 — Dust Separation and Feed
The negative-pressure fan draws dust, fine soil particles, and chaff from the material stream before it enters the fork feeding mechanism and compression chamber.
Step 3 — High-Density Baling
Clean, short-fibre material is compressed in the 460 x 360 mm chamber. Twin D-type knotters automatically bind each bale with two ropes for immediate ejection.
