Running two baling chambers simultaneously cuts your effective field time in half. The 9YFS-2.2 Double Chamber Square Baler ejects two rope-tied square bales per cycle — driven by four D-type knotters working in coordinated pairs. For commercial baling contractors and large farm operations working under time pressure during harvest windows, this dual-output design delivers throughput that no single-chamber machine at equivalent weight and power can match.
Product Overview
The 9YFS-2.2 is a trailed square baler built around a twin-chamber compression architecture. Two independent 460 x 360 mm compression chambers are arranged side by side within the machine body, each served by its own pair of D-type knotters — four in total. With every completed plunger cycle, two fully formed, rope-bound square bales are released simultaneously from the dual rear outlet. No other adjustment or operator action is required between cycles; the entire sequence from pickup to ejection is fully automatic.
The machine is tractor-towed and PTO-driven, requiring a minimum of 51.5 kW (approximately 70 HP) for sustained dual-chamber operation. A 2200 mm spring-tooth pickup reel collects wheat straw, rice straw, cotton stalks, corn stover, and a range of forage grasses across a wide working swath, channelling all material through the fork feeding mechanism into both chambers evenly. At 3115 kg and 5600 mm in length, the 9YFS-2.2 is the highest-capacity square baler in the Ever-Power range.
Key Features
Dual Output: Two Bales Released Per Plunger Cycle
Both compression chambers operate from a single plunger drive in perfect synchronisation. Material from the pickup reel is distributed evenly between the two chambers by the fork feeding mechanism, ensuring that both bales form at identical density and cross-section with each cycle. When the plunger stroke completes, all four knotters fire simultaneously — two ropes per bale — and both finished bales are ejected together. This design eliminates the mechanical inefficiency of single-chamber machines, where the plunger returns empty after each ejection cycle. The result: roughly double the bale count per operating hour at the same field speed and tractor fuel consumption.
2 x 2 D-Type Knotter System
Four D-type knotters — two per chamber — tie two ropes across each bale for secure, field-durable binding. The D-type rotating bill hook is the proven industry standard for commercial square baling: it forms a mechanically locked knot in a single stroke, operates cleanly at high cycle rates without jamming, and is straightforward to service in the field. All four knotters fire synchronously via a shared cam drive, ensuring consistent knot tension and uniform bale shape across both chambers throughout an extended operating day. Individual knotter adjustment points are accessible from ground level without disassembly.
2200 mm Spring-Tooth Pickup
The 2200 mm spring-tooth pickup reel sweeps a working width that matches the machine’s dual-chamber footprint, collecting material across a broad swath in a single pass. Each spring tooth flexes individually on contact with soil or stones, recovering material without digging in and resetting immediately for the next pass. Even distribution of collected material across the full 2200 mm width is maintained by the fork feeding mechanism before material enters the chambers, eliminating the density imbalance between left and right chambers that would otherwise develop if one side received more material than the other.
Power Matching at 51.5 kW and Above
Sustaining two compression chambers, four knotters, and a 2200 mm pickup from a single PTO shaft demands continuous high torque. The 9YFS-2.2 is engineered for tractors of 70 HP and above, and operates most efficiently in the 80-120 HP range where the drive train can maintain consistent compression density under full crop loading. Operators running at the 70 HP minimum will find the machine functional but should reduce forward speed in dense crop conditions to avoid PTO overload.
Automatic Rope Baling — Fully Unattended Operation
Once set up and engaged, the 9YFS-2.2 requires no operator intervention during the baling cycle. Bale length is set by a mechanical star-wheel counter on each chamber independently, allowing the operator to adjust output bale length to suit downstream handling requirements. Twine tension is set at the needle assembly and maintained automatically throughout the day. One tractor driver can operate the full machine without an assistant.
Field Applications and Typical Use Cases
The primary crop applications include wheat straw, rice straw, cotton stalks, corn stover, mixed forage grasses, and leguminous fodder plants. Baled output from this machine serves a range of downstream uses depending on regional agricultural practice and buyer requirements: livestock bedding (cattle, poultry, equine), animal roughage feed, straw recycling operations, biomass fuel feedstock, paper industry raw material, and field residue management.
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
The 9YFS-2.2 operates on flat ground and gentle paddy-field terrain. Field surface should be reasonably free of large stones and hard objects to avoid spring-tooth damage. Optimal bale density is achieved when crop moisture content falls within 15-25%. At higher moisture levels, bale density decreases and knotter jam risk increases; at lower moisture levels (very dry, brittle straw), pickup efficiency may be reduced at high forward speeds.
How It Works
Step 1 — Pickup
The 2200 mm spring-tooth reel lifts windrowed material off the field and delivers it evenly to the fork feeding mechanism serving both chambers.
Step 2 — Dual Compression
The reciprocating plunger builds bales in both 460 x 360 mm chambers simultaneously, compacting material slice by slice to the target density.
Step 3 — Dual Binding and Ejection
All four D-type knotters fire together. Two ropes bind each bale simultaneously and both completed bales are ejected from the dual rear outlet.
