How the EP-9YG-2.2 Round Baler Works
Unlike square balers that compress crop in a reciprocating plunger chamber, the EP-9YG-2.2 forms bales inside a fixed-diameter roll-drum chamber lined with 18 large-diameter (Φ222 mm) pressing rollers. Crop is continuously fed and rolled into an ever-tighter cylinder until the preset diameter and density are reached, at which point the automatic net-wrapping sequence triggers without any operator input.
- Spring-Tooth Pickup: The 2,200 mm wide spring-tooth reel lifts windrowed crop from the ground with hardened tines that minimise leaf shatter and soil contamination across all crop types. Hydraulic height adjustment with floating capacity allows the pickup to automatically follow ground contours, maintaining clean crop collection even on uneven field surfaces.
- Continuous Screw Feeding: Picked-up material is delivered into the compression chamber by a continuous screw feeding mechanism, which provides an uninterrupted, consistent crop flow into the roll-drum chamber — eliminating the charge-by-charge feeding cycle of square balers and enabling truly continuous forward operation.
- Roll-Drum Compression: Inside the 1,400 mm wide roll-drum chamber, 18 pressing rollers (Φ222 mm each) rotate to continuously compact the growing bale. As the bale diameter increases toward the preset 1,220 mm target, the rollers apply progressively higher radial pressure, producing a uniformly dense, stable bale cylinder with a consistent cross-section from core to outer ring.
- High-Precision Net Wrapping: The handheld colour touch screen monitors bale diameter and weight in real time via high-precision displacement sensors. When the preset target is reached, the fully automatic net-wrapping system engages, applies the programmed number of net loops (sensor-controlled for cost optimisation), cuts the net, and signals the operator that the bale is ready for ejection.
- Bale Ejection: The rear tailgate opens hydraulically, the completed round bale rolls out onto the field surface, and the tailgate closes automatically — the next bale forming cycle begins immediately. The operator selects automatic or manual mode via the touch screen depending on field conditions and operator preference.
⚙ Smart Control Highlights
- Handheld colour touch screen — stable and reliable operation with precise bale weight control
- Automatic and manual operating modes — operator selects based on field condition
- High-precision displacement sensor monitors entire baling process at a glance
- Sensor-controlled net-wrap loop count — precise material cost control per bale
🔩 PTO Shaft — High-Torque Driveline Requirements for the 9YG-2.2
The EP-9YG-2.2 draws 110–150 kW continuously through the PTO shaft to drive the 18-roller compression chamber, continuous screw feeder, hydraulic system, net-wrapping mechanism, and electronic control auxiliaries simultaneously. This is a substantially higher continuous torque load than a square baler of equivalent pickup width. Shaft selection must account for both steady-state rotor torque and intermittent peak loads from dense crop ingestion. Key requirements:
- High continuous torque rating: The shaft must be rated for the full 150 kW upper power limit with an appropriate safety factor. A heavy-duty friction torque limiter (not shear-bolt) is strongly recommended to handle the continuous high-torque cycle without bolt replacement downtime.
- PTO speed and spline: The 9YG-2.2 is typically configured for 1,000 rpm input (21-spline). Confirm the exact input specification with our technical team before ordering the shaft.
- Telescoping length and articulation angle: At 4,100 mm overall length, the 9YG-2.2 has a relatively short hitch-to-input distance. Measure carefully and ensure the shaft telescopes freely through the full turning radius without bottoming or separating.
- CE-rated full safety guard: Mandatory. The high continuous PTO speed and torque make an undamaged, correctly fitted safety guard critical for operator protection at all times.
Our preferred supply partner provides CE-certified, high-torque round-baler driveline solutions. For dimensional and torque-rating reference, we recommend reviewing their पीटीओ शाफ्ट range for large balers to identify the correct shaft specification for your tractor-baler combination.
Core Advantages of the EP-9YG-2.2 Round Baler
Handheld Touch Screen — Precision Bale Weight Control
The handheld colour touch screen combined with a high-precision displacement sensor allows the operator to monitor bale weight and density in real time and set exact bale targets. Automatic and manual modes provide operational flexibility for different crop types and contractor requirements.
18-Roller Chamber — Superior Bale Density and Uniformity
The 18-roller (Φ222 mm) roll-drum chamber applies radial compression across the full 1,400 mm bale width simultaneously, producing uniformly dense 1,220 mm diameter bales with a consistent cross-section that resist deformation during storage and transport.
Continuous Screw Feeding — No Charge Interruption
The continuous screw feeding mechanism delivers an uninterrupted crop stream into the roll chamber, eliminating the charging-and-compression cycle of square balers. This allows higher forward field speeds and greater daily throughput on large acreages.
Fully Automatic Net Wrapping with Loop Control
High-precision sensors accurately position the number of net-wrap loops per bale, enabling the operator to optimise net consumption per bale precisely — reducing material costs at scale without compromising bale protection during outdoor storage or transport.
Full-Auto Thin Oil Lubrication System
The fully automatic thin oil lubrication system ensures smooth running of the entire chain drive system and extends its service life significantly. Grease lubrication points use a centralised oil supply method, reducing daily maintenance time and minimising unscheduled downtime during peak harvesting seasons.
Globally Sourced Key Components
The drive shaft, bearings, clutch, chain drive, and electronic control system are globally sourced from world-renowned brands, ensuring every critical component meets international quality standards. This eliminates the reliability gap that sometimes affects lower-cost machinery built entirely from local-spec components.
Hydraulic Pickup with Floating Capacity
Hydraulic adjustment of pickup height combined with an automatic floating capacity allows the pickup reel to follow field surface variations without manual intervention, maintaining consistent crop collection on undulating terrain and easing daily cleaning and maintenance access.
Factory-Direct Value at Commercial Scale
Sold factory-direct with a comprehensive global spare-parts export programme, the EP-9YG-2.2 delivers large-diameter round-baler capability — complete with touch screen control, automatic net wrapping, and auto lubrication — at a substantially lower purchase price than equivalent Western-brand machines.
Structure Design and Key System Engineering
Main Frame: Heavy-duty Q355B structural steel, robotic MIG welded and reinforced to absorb the high continuous torque loads of the 18-roller compression system and the continuous screw feeder operating simultaneously. Multi-pass shot-blasting (Sa 2.5) plus epoxy primer and polyurethane topcoat delivers long-term corrosion resistance in humid forage-field environments.
Roll-Drum Compression Chamber: The chamber houses 18 pressing rollers (Φ222 mm each) arranged in a fixed-diameter configuration. All roller shafts are mounted in heavy-duty sealed bearings sourced from internationally recognised bearing brands. Roller surfaces are hardened and precision-ground to maintain consistent diameter and surface finish across the service life, ensuring uniform bale density from the first to the ten-thousandth bale.
Continuous Screw Feeding System: The screw feeder is fabricated from hardened wear-resistant steel with a profile optimised for consistent crop flow across the full range of supported materials — from light-density dried grass to high-moisture fresh-cut alfalfa and coarse straw. The screw mechanism eliminates the crop-slugging that can cause uneven density in square balers at high forward speeds.
Automatic Net Wrapping and Control: The net-wrapping mechanism is driven by a dedicated motor and controlled by the electronic system through the handheld touch screen. High-precision displacement sensors monitor bale growth continuously. Net-wrap loop count is set digitally and executed automatically, eliminating operator error in net application and ensuring consistent bale protection across an entire day of operation.
Lubrication Systems: The fully automatic thin oil lubrication system services all chain drive points via a centralised pump on a programmable cycle, eliminating the need for the operator to manually grease individual chain points during the working day. Centralised grease points for bearings and pivot joints are consolidated into accessible banks to reduce servicing time.
Key Component Sourcing: The drive shaft, bearings, clutch assembly, chain drive components, and electronic control module are globally sourced from world-renowned brands including internationally recognised bearing, chain, and electronics manufacturers. This component strategy ensures long-term parts availability and consistent performance across the machine service life.
Typical Application Scenarios
🐄 Alfalfa Export and Premium Forage Baling
Large-diameter 1,220 mm round bales with precise sensor-controlled net wrapping are a standard format for containerised alfalfa export to Middle Eastern and Asian markets. Touch screen bale weight control ensures every bale meets the weight specification required by export logistics and purchase contracts, minimising rejected loads at destination ports.
🌾 Wheat and Rice Straw at Commercial Scale
Following the combine harvester, the 9YG-2.2 produces large round bales from wheat or rice straw windrows at a rate that outpaces square balers of equivalent pickup width — thanks to continuous feeding and no plunger-cycle interruption. Bales are sold to paper mills, mushroom substrate producers, and biomass energy plants.
🌿 Silage Grass and High-Moisture Forage
The roll-drum chamber handles high-moisture grass and silage material that can plug fixed-chamber square balers. Net-wrapped round bales of wilted grass at 40%–55% moisture are commonly over-wrapped with stretch film to create sealed silage bales for winter livestock feeding. The precise net-loop control reduces film requirement per bale.
🔥 Biomass Energy and Corn Stover
Large round bales of corn stover, sorghum residue, and mixed straw are produced at high daily tonnage for biomass co-firing plants and pellet mill feedstock supply contracts. The high-power 110–150 kW drive system handles bulky, tangled corn stover without the chamber plugging that affects lower-power machines.
Selection Guide — Round Baler vs. Square Baler: Choosing the Right Format

Frequently Asked Questions — EP-9YG-2.2 Round Baler
Q1: What is the key functional difference between the 9YG-2.2 round baler and the EP square balers?
The 9YG-2.2 forms cylindrical round bales (1,220 mm diameter) inside a roll-drum chamber using 18 pressing rollers, wrapped with net, and is designed for continuous-feed high-throughput operation with a 110–150 kW tractor. EP square balers produce 460 x 360 mm rectangular bales using a reciprocating plunger and twine knotter, requiring 40–100 hp tractors. Round bales are better for silage, outdoor weathering tolerance, and large-volume alfalfa export; square bales are better for compact storage, manual handling, and export pallet logistics.
Q2: How does the handheld touch screen control the baling process?
The colour touch screen, working in combination with a high-precision displacement sensor, monitors bale diameter and density continuously during formation. The operator sets target bale weight and net-wrap loop count via the touch screen. When the bale reaches the preset target, the automatic net-wrapping sequence triggers without any operator input. Both automatic mode (fully hands-off from bale start to ejection) and manual mode (operator triggers wrapping and ejection manually) are available for different field conditions and operator preferences.
Q3: Can the 9YG-2.2 be used for silage baling?
The 9YG-2.2 produces net-wrapped round bales suitable as the first stage of round bale silage production. After ejection, net-wrapped bales of wilted grass (typically 40%–55% DM moisture) are over-wrapped with stretch silage film using a separate bale wrapper to create a sealed anaerobic environment. The high-precision net-wrap loop control on the 9YG-2.2 reduces the film requirement in the subsequent wrapping stage, saving material costs at scale.
Q4: What routine maintenance does the 9YG-2.2 require?
Daily: check automatic oil lubrication system reservoir level and top up if required, inspect pickup tines for damage, check net-wrap roll supply and tension, verify hydraulic fluid level. Weekly: inspect all roller bearings for noise or play, check chain tension and sprocket wear, inspect hydraulic hoses and fittings. Seasonal: drain and replace gearbox and chain drive oil, inspect all roller surfaces for wear, replace worn pickup tines, test electronic control system sensor calibration. The centralised oil supply and grease manifold design significantly reduces daily servicing time compared with machines requiring individual point greasing.
Q5: What net-wrap types are compatible with the 9YG-2.2?
The 9YG-2.2 net-wrapping system is compatible with standard round-baler net wrap rolls in widths matched to the 1,400 mm compression room width. UV-stabilised polyethylene net wrap in 64–72 gsm weight range is recommended for outdoor-stored bales. For silage bales to be over-wrapped with stretch film, a lighter 50–64 gsm net wrap minimises net tenting and ensures good stretch-film adhesion. Contact our technical team for net-wrap roll core diameter and carrier specifications before first use.
Q6: What warranty and spare-parts support is included with the EP-9YG-2.2?
The EP-9YG-2.2 carries a 24-month manufacturer warranty on the main frame, gearbox, and structural components, and a 12-month warranty on the roller assemblies, net-wrapping mechanism, and electronic control system. Support is direct from our factory engineering team — no dealer intermediary required. All fast-wear parts (pickup tines, net-wrap knife, roller bearings, chain sets, hydraulic seals) are held in export stock and dispatched globally within 48 hours. A recommended seasonal spare-parts kit is available with each new machine on request.
