Understanding the Energy Crop Opportunity<\/p>\n

1. Why Switchgrass and Miscanthus Are Redefining Biomass Harvesting \u2014 and Why the Round Baler Is Central to That Shift<\/h2>\n

Switchgrass (Panicum virgatum) and miscanthus (primarily Miscanthus x giganteus and Miscanthus sinensis) are the two perennial energy crops most actively cultivated for solid biomass production across temperate regions. Both species share a distinctive harvesting profile: they are typically cut only once per year, in winter or early spring after natural senescence has reduced the moisture content of standing stems to 15\u201325%, and the resulting dry material is collected and densified into bales for transport to power plants, pellet mills, or industrial biorefinery facilities. The round baler machine is the dominant collection technology for both crops because it handles their tall, coarse, fibrous stems more efficiently than large square balers at equivalent field scale, while producing bales that are well-suited to the bulk handling systems used at biomass receiving facilities.<\/p>\n

In Korea, the cultivation of miscanthus \u2014 particularly the native Miscanthus sinensis var. purpurascens known locally as eoksae \u2014 is expanding in the context of the national Renewable Portfolio Standard (RPS), which requires power utilities to source increasing proportions of their generation from renewable sources. Switchgrass, while less established in Korean agriculture, is being evaluated as a marginal land cover crop under government programs promoting renewable energy crops on land unsuitable for food production. Korean agricultural equipment importers and biomass project developers evaluating round baler options for these applications need to understand the specific mechanical demands that these energy crops impose on baling equipment \u2014 demands that differ meaningfully from conventional grass hay production and require careful machine selection and operator preparation.<\/p>\n

This guide covers the key technical dimensions of switchgrass and miscanthus baling: what makes these crops mechanically challenging, what manufacturing and material characteristics the 9YG round baler series brings to the task, and how the gearbox and drivetrain are designed to handle the torque loads that tall, fibrous energy crops generate. It also addresses the regulatory context governing biomass machinery and energy crop production in Korea, the European Union, the United States, and other producing regions.<\/p>\n<\/div>\n

Crop Mechanics<\/p>\n

2. What Makes Switchgrass and Miscanthus Technically Demanding for Round Baler Operation?<\/h2>\n

Both switchgrass and miscanthus grow to heights of 2\u20134 meters in a productive stand, with stem diameters at the base ranging from 8\u201320 mm for switchgrass and 15\u201330 mm for mature miscanthus canes. When these crops are cut in their dried, senescent state, they form a dense, tangled mat of long, rigid stems on the field surface rather than the relatively uniform, short-length windrow material produced by a grass hay crop. This mat behavior creates several distinct problems for the round baler: the pickup system must deal with stems that are too long to pass cleanly through the feeding mechanism without bridging across the throat between pickup and bale chamber; the coarse stems impose high compaction resistance per unit volume inside the bale chamber; and the dried silica-rich surfaces of both crops accelerate abrasive wear on chain link surfaces, tine tips, and roller shells.<\/p>\n

Miscanthus in particular is notable for its cane stiffness at harvest time. Unlike switchgrass, which collapses into a relatively manageable windrow after cutting, miscanthus canes retain considerable rigidity even at 15% moisture content, and their natural tendency is to lie parallel to the direction of cutting, forming a layered rather than tangled windrow profile. This parallel-lay windrow is actually helpful for pickup efficiency \u2014 the spring-tine pickup can engage the stems longitudinally rather than having to break through a mat \u2014 but the stiffness of individual canes means that the chamber must develop higher compressive force than would be needed for the same mass of soft forage grass to produce a bale at the target density range of 100\u2013200 kg\/m\u00b3.<\/p>\n

Switchgrass presents a different mechanical profile. Its finer stems and more tangled windrow structure mean that pickup blockage \u2014 where stems bridge across the pickup rotor width rather than feeding cleanly into the chamber \u2014 is a more frequent event than with miscanthus. The 9YG series axial-flow semi-forced feeding mechanism is designed specifically to address this: by providing a continuous, guided flow path from the pickup into the bale chamber without the gaps and recirculation zones that cam-and-guard pickup designs create, it reduces the frequency of blockage events that would otherwise require the operator to stop and clear the pickup manually.<\/p>\n<\/div>\n

Manufacturing Structure<\/p>\n

3. Frame Engineering and Chamber Design for Tall, Fibrous Energy Crop Baling<\/h2>\n

The structural challenge of baling miscanthus and switchgrass at commercial scale stems from the combination of high individual stem resistance to compaction, variable windrow density across large production fields, and the extended daily operating hours typical of commercial biomass harvest contracts. A round baler deployed across a 200-hectare miscanthus block may produce several hundred bales per working day for multiple consecutive days \u2014 a duty cycle that exposes every structural node in the machine to cyclic fatigue loading that accumulates over the harvest season. The quality of CNC laser-cut structural steel fabrication and automated welding at the 9YG manufacturing facility directly determines how consistently the machine’s structural behavior is maintained across this kind of intensive use.<\/p>\n

On the 9YG-2.24D series, the bale chamber measures 1,200 mm in diameter and 1,400 mm in width, supported by 18 press rollers each measuring 222 mm in diameter. The roller array uses dual-side chain drive on both chamber side plates, which distributes the compressive load symmetrically regardless of how the miscanthus canes or switchgrass stems are distributed within the forming bale. This balance is particularly important for energy crop baling where stem alignment variability within the chamber is higher than for a uniform forage grass windrow. The structural endplates of the chamber are manufactured from heavier-gauge material than the side panels, providing extra resistance to the bowing and deflection that elevated compressive forces would otherwise cause at the chamber ends where the roller bearing housings are located.<\/p>\n

The tailgate on the 9YG-2.24D Classic uses buffer cylinders to absorb the mechanical shock of rapid gate opening during bale ejection \u2014 a feature that prevents the fatigue damage at the gate hinge welds that accumulates when a heavy, dense energy crop bale rolls against the opening gate under gravity. The H-type ferrule hydraulic fittings used throughout the system provide reliable high-pressure sealing that maintains ejection speed consistency across the extended operating periods of commercial biomass harvest contracts. The drawbar connection, fabricated from boxed-section structural steel, handles the lateral loading that arises when the baler is towed at working speed across the undulating post-harvest surface of a miscanthus or switchgrass field.<\/p>\n<\/div>\n

Material System<\/p>\n

4. Chain Grades, Tine Alloys, Roller Design, and Surface Treatments for Abrasive Energy Crop Conditions<\/h2>\n

The material demands of miscanthus and switchgrass baling are dominated by abrasion, high compressive force, and the consequences of operating in the late-season conditions when these crops are harvested. Winter harvesting means cold temperatures that reduce lubricant film thickness on chain and bearing surfaces; dry, rigid stems that concentrate contact stress on tine tips and roller shells; and the silica content of grass epidermal tissue that turns every contact surface into a microscale grinding interface. The material selection across the 9YG drivetrain reflects engineering decisions made specifically for this kind of extended, abrasive workload.<\/p>\n

\n
\n

20A Heavy Roller Chain \u2014 Dual Side Drive<\/h4>\n

The 9YG-2.24D S9000 Transcend and Classic models use 20A specification roller chain on both sides of the rear chamber drive. At the elevated compressive forces needed to form dense miscanthus bales \u2014 where the coarse canes resist compaction significantly more than soft forage \u2014 the dual-side chain arrangement maintains even tension across both sides of the roller array, preventing the differential elongation that creates misalignment and uneven bale density in single-side drive systems. For winter switchgrass harvesting, where ambient temperatures may be near or below freezing in Korean highland and northern regions, the chain should be lubricated with a low-temperature-rated penetrating lubricant rather than a standard grease to ensure adequate film coverage at reduced operating temperatures.<\/p>\n<\/div>\n

\n

High-Tensile Spring Steel Pickup Tines<\/h4>\n

Spring steel pickup tines on the 9YG series are formed from high-tensile material that provides the combination of flexibility and fatigue resistance needed for energy crop harvesting. When engaging long miscanthus canes lying in a parallel-lay windrow, the tine must flex on contact and return quickly to position without residual deformation \u2014 a cycle it performs thousands of times per working day. The 2,240 mm pickup width on the 9YG-2.24D series covers a wide swath per pass, which is important for miscanthus production fields where the cutting windrow width is determined by the header width of a dedicated disc mower rather than a narrow hay conditioner. Tine tip wear in energy crop applications is typically 30\u201350% faster than in hay applications due to higher stem rigidity and silica content \u2014 this should be factored into spare round baler parts inventory planning before the harvest season.<\/p>\n<\/div>\n

\n

Press Roller Tubes and Bearing Sealing<\/h4>\n

The 18 press rollers in the bale chamber are steel tube construction with machined journal ends and fitted sealed bearings. Miscanthus cane fragments \u2014 particularly the outer epidermal silica layer that breaks away from dried canes during compression \u2014 are highly abrasive and will infiltrate open or inadequately sealed bearing housings over time, causing abrasive failure of the bearing race. Pre-season replacement of all roller end bearings with verified sealed-unit specification should be part of the pre-harvest preparation for any energy crop deployment. Roller surface condition should also be checked for wear ridges or diameter reduction that would create uneven compaction zones within the bale, since bale geometry consistency is a contractual requirement for most commercial biomass supply agreements.<\/p>\n<\/div>\n

\n

Frame Coating for Cold-Season Operation<\/h4>\n

Machines harvesting switchgrass or miscanthus in Korea’s winter window \u2014 typically January to early March for miscanthus, and October to December for switchgrass \u2014 operate in conditions where overnight condensation on unprotected steel surfaces is a regular occurrence. Electrostatic powder coating applied over a prepared steel surface after CNC fabrication provides a moisture-resistant barrier that prevents the condensation-and-drying corrosion cycle that attacks unprotected surfaces repeatedly through a winter harvest season. For machines stored outdoors or in open-sided field shelters between seasons, annual coating inspection and spot priming of any chips is the single most cost-effective maintenance step for extending structural service life.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

Biomass Economics<\/p>\n

5. How Bale Density Determines the Commercial Viability of Switchgrass and Miscanthus Supply Chains<\/h2>\n

For energy crop biomass supply chains, bale density is not merely a machine performance metric \u2014 it is a direct determinant of the cost-per-GJ delivered to the end-use facility. The transport step in a solid biomass supply chain typically accounts for 30\u201350% of the total delivered cost, and transport cost is driven by the number of truck loads required to move a given energy quantity. A round baler machine that consistently produces bales at the upper end of the 100\u2013200 kg\/m\u00b3 target range delivers twice the mass per bale compared to one operating at the lower limit \u2014 which can reduce the truck load count for a given field by 50% and cut transport costs proportionally. For Korean biomass project operators supplying under fixed-delivery contracts to RPS-certified power plants, this density consistency translates directly into operational margin.<\/p>\n

Miscanthus baled at the post-senescence moisture content of 15\u201320% and a density of 150 kg\/m\u00b3 from a 9YG-2.24D chamber (\u00d81300\u00d71400 mm) produces bales weighing approximately 280 kg. At a net calorific value of approximately 16\u201317 MJ\/kg for dry miscanthus (lower heating value basis), each bale represents roughly 4.5\u20134.8 GJ of thermal energy. At a productivity rate of 40\u2013100 bales per hour, a full working day of baling produces a substantial fuel inventory. Switchgrass baled under similar conditions produces slightly lighter bales due to the material’s lower bulk density at equivalent compression, but the energy content per kilogram of dry matter is comparable to miscanthus, so the per-bale energy value tracks the bale weight closely.<\/p>\n

The sensor-controlled density management system on the 9YG-2.24D series maintains this output consistency across the full range of windrow density variation encountered in a production field. When a section of the miscanthus stand yields heavier-than-average material due to better growing conditions, the sensor detects that the target density has been reached earlier in the bale formation cycle and triggers the wrapping and ejection sequence at the correct point. When the stand is thinner or the windrow was raked more loosely, the machine continues filling until the same density target is reached. Every bale that leaves the machine carries the same mass \u2014 a uniformity that commercial biomass buyers and plant operators price positively in their supply contracts.<\/p>\n

Power Transmission<\/p>\n

6. The Round Baler Gearbox Under Energy Crop Load Conditions: Design Considerations and Maintenance Demands<\/h2>\n

The round baler gearbox in a miscanthus or switchgrass harvest operation faces a torque demand profile that is more variable and in some respects more severe than in conventional hay baling. Miscanthus canes in particular enter the bale chamber in bundles \u2014 because the parallel-lay windrow tends to deliver clusters of aligned stems rather than a random mix \u2014 and these clusters impose brief but intense torque spikes on the gearbox input as the chamber suddenly needs to compress a higher-than-average mass of material. The frequency of these spikes is higher on energy crops than on hay, and their peak magnitude can exceed what the gearbox experiences in normal hay operation by a substantial margin.<\/p>\n

The proprietary dual-coupling gearbox on the 9YG-2.24D S9000 Transcend is rated for significantly higher input torque than standard-class agricultural gearbox designs, providing the mechanical headroom to absorb these energy crop cluster events without operating at the edge of its rated capacity. The design also incorporates a safety torque shaft in the PTO driveline between the tractor and gearbox input. This component functions as a mechanical fuse: when an instantaneous overload \u2014 such as a large knot of miscanthus canes jamming simultaneously against the press rollers \u2014 exceeds the shaft’s trip torque, the shaft absorbs and releases the energy without transmitting it as a destructive shock through the gearbox internals. For commercial biomass operators running machines 8\u201312 hours per day through the energy crop harvest window, this protection mechanism prevents the kind of gearbox failure that would take a machine out of service for days during the narrow harvest period.<\/p>\n

Gearbox oil management in winter energy crop operations requires attention to low-temperature lubricant behavior. Standard SAE 90 gear oil, which is adequate for summer hay baling at ambient temperatures above 15\u00b0C, may be too viscous for effective splash lubrication in a gearbox that starts cold in sub-zero conditions. Using a multi-viscosity gear oil such as SAE 75W-90 in the gearbox during the winter energy crop harvest window ensures adequate lubricant flow around gear contacts and bearing surfaces from the moment the machine begins operating, rather than waiting for the oil to warm up through frictional heating from a standing-viscosity cold start.<\/p>\n<\/div>\n

<\/p>\n

Model Selection<\/p>\n

7. Choosing the Right Round Baler for Switchgrass and Miscanthus at Different Operating Scales<\/h2>\n

The right model depends on the area of energy crop to be harvested, the available tractor power, whether the operator is running a pilot project or a full commercial supply contract, and whether a single machine will also be used for other crops during the rest of the year. The table below summarizes the key selection considerations for each model in the 9YG range in an energy crop context.<\/p>\n

Regulatory Landscape<\/p>\n

8. Energy Crop Policies, Machinery Safety Standards, and Gearbox Regulations in Key Producing Regions<\/h2>\n

Energy crop biomass supply chains are subject to both agricultural machinery safety regulations and energy sector sustainability standards. The following frameworks are relevant to operators in Korea, the EU, the United States, and other regions where switchgrass and miscanthus are cultivated commercially.<\/p>\n

\n
\n

Republic of Korea \u2014 Renewable Portfolio Standard (RPS) and Energy Crop Biomass Criteria<\/h4>\n

Korea’s Renewable Portfolio Standard, administered by the Korea Energy Agency (KEA), requires power utilities to source a growing share of generation from renewable sources. Solid biomass feedstocks \u2014 including domestic miscanthus and imported energy crop biomass \u2014 qualify for Renewable Energy Certificates (REC) under the RPS framework subject to sustainability and feedstock origin criteria. Round balers used in certified biomass supply chains should be capable of providing bale density records that support feedstock traceability documentation. ISO 9001-certified manufacturing processes support the quality management trail required for REC audit compliance. For Korean agricultural enterprises cultivating miscanthus under energy crop incentive programs, the round baler is the primary capital equipment item in the harvesting chain.<\/p>\n<\/div>\n

\n

Korea RDA Type Approval \u2014 Agricultural Machinery Safety<\/h4>\n

Round balers used in Korea for commercial purposes, including energy crop harvesting contracts, must hold Rural Development Administration (RDA) type approval to be eligible for national agricultural machinery purchase subsidies. The RDA evaluation covers safety guarding of the PTO shaft, chain drive, and bale ejection zone, as well as performance criteria for bale density and productivity. Energy crop operators considering round baler purchase in Korea should confirm the specific approval status of their chosen model with the manufacturer or importer at the time of inquiry.<\/p>\n<\/div>\n

\n

European Union \u2014 RED II and Energy Crop Sustainability Requirements<\/h4>\n

The EU Renewable Energy Directive (RED II) establishes mandatory greenhouse gas savings thresholds and land-use requirements for solid biomass qualifying for renewable energy support. Switchgrass and miscanthus production in EU member states qualifies under Article 29 of RED II provided the feedstock meets minimum GHG savings of 70% (for new installations from 2021) and land use criteria excluding high-biodiversity or high-carbon stock land. Round baler manufacturers supplying equipment into EU biomass supply chains are expected to provide machinery compliant with the EU Machinery Directive 2006\/42\/EC CE marking requirements, with specific focus on PTO shaft and chain drive guarding relevant to the safety provisions of ISO 4254-7.<\/p>\n<\/div>\n

\n

United States \u2014 USDA Biomass Crop Assistance Program (BCAP)<\/h4>\n

In the United States, switchgrass is the most widely cultivated dedicated energy crop, supported under the USDA Biomass Crop Assistance Program (BCAP), which provides establishment and annual payments to growers supplying qualified biomass conversion facilities. Eligible machinery used in BCAP-supported operations must meet OSHA agricultural equipment safety standards under 29 CFR 1928, which covers PTO shaft guarding requirements directly relevant to the round baler gearbox input connection. ASABE standard S318 provides the color-coding and connection specification framework for PTO shafts \u2014 a reference standard that informs machinery compliance documentation for US-market supply chains.<\/p>\n<\/div>\n

\n

United Kingdom \u2014 Post-Brexit Biomass Strategy and HSE Machinery Regulations<\/h4>\n

The UK Biomass Strategy published in 2023 sets out a framework for sustainable domestic biomass production, including energy grasses and perennial crops. Round baler machinery used in miscanthus and switchgrass harvesting on UK farms must comply with the UK Machinery Regulations 2008 (SI 2008\/1597), which retains the substance of the EU Machinery Directive post-Brexit. The Health and Safety Executive (HSE) Farm Safety Partnership guidance specifically identifies PTO shaft entanglement and baler ejection zone incidents as priority hazard categories for UK agricultural operators, with relevant guidance notes that energy crop operators should review before seasonal deployment.<\/p>\n<\/div>\n

\n

ISO 4254-7 \u2014 International Safety Standard for Baling Machines<\/h4>\n

ISO 4254-7 is the international reference standard for agricultural baling machine safety, covering guarding of the pickup rotor, bale chamber, and ejection zone; PTO connection safety provisions; and warning label requirements for crush and entanglement hazards. For round balers deployed in energy crop operations across multiple jurisdictions \u2014 particularly for Korean operators managing overseas switchgrass or miscanthus projects \u2014 compliance documentation referencing ISO 4254-7 provides a consistent safety benchmark that satisfies the majority of national machinery safety authority requirements without requiring jurisdiction-specific re-certification for each country of operation.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

FAQ<\/p>\n

Frequently Asked Questions: Round Balers for Switchgrass and Miscanthus Energy Crops<\/h2>\n
\n+<\/span>
\nQ1. What round baler machine is best for harvesting miscanthus on a large Korean RPS biomass supply project?<\/summary>\n
\n

For large Korean RPS biomass supply projects harvesting miscanthus, the 9YG-2.24D Transcend is the most capable option. Its dual-coupling gearbox handles the torque spikes generated by miscanthus cane clusters entering the bale chamber, and the safety torque shaft protects the drivetrain from sudden overload events during the dense winter harvest. At 40\u2013100 bales per hour with sensor-controlled density management, it produces the consistent, high-density bales that maximize transport efficiency for RPS supply contracts. For projects with flatter terrain and fewer turning constraints, the 9YG-2.24D S9000 provides comparable bale quality at a similar throughput rate.<\/p>\n<\/div>\n<\/details>\n

\n+<\/span>
\nQ2. How does the round baler gearbox handle the torque spikes from miscanthus cane bundle feeding during commercial biomass harvest?<\/summary>\n
\n

Miscanthus canes in a parallel-lay windrow tend to enter the bale chamber in clusters, creating brief torque spikes that can significantly exceed the steady-state load level. The dual-coupling gearbox on the 9YG-2.24D Transcend is rated for a higher torque capacity than standard class gearboxes, providing mechanical headroom above the steady operating load that absorbs these spikes without stressing gear tooth contact surfaces. The safety torque shaft in the PTO driveline provides a secondary protection layer \u2014 if a cluster event is severe enough to exceed even the gearbox’s rated capacity, the torque shaft trips and releases the energy rather than allowing it to propagate through the machine as a destructive shock.<\/p>\n<\/div>\n<\/details>\n

\n+<\/span>
\nQ3. What round baler parts wear fastest when harvesting switchgrass in autumn conditions and how should operators prepare?<\/summary>\n
\n

In switchgrass harvesting, the highest-wear components \u2014 in order of replacement frequency \u2014 are spring tine pickup fingers (silica in the epidermal tissue accelerates tip wear), roller chain links and pins (silica infiltration and the higher compressive forces of energy crop baling), press roller end bearings (seal integrity is critical given silica particle infiltration risk), and net wrap knife blades. Operators should stock replacement tines, a minimum of one full chain pitch length replacement, and a set of roller end bearings before the switchgrass harvest season begins. Chain lubrication intervals should be shortened to every 6\u20138 operating hours compared to the standard recommendation for conventional hay, and a penetrating low-temperature lubricant should be used if ambient temperatures at harvest time are below 5\u00b0C.<\/p>\n<\/div>\n<\/details>\n

\n+<\/span>
\nQ4. How does the round baler application differ between switchgrass and miscanthus, and which machine specifications matter most for each?<\/summary>\n
\n

Switchgrass produces a more tangled, mixed-length windrow than miscanthus, making pickup blockage a more frequent concern \u2014 the axial-flow semi-forced feeding mechanism on the 9YG series is particularly valuable here. Miscanthus forms a stiffer, heavier windrow of parallel canes that are easier to pick up but harder to compress, placing greater demand on the gearbox torque capacity and chamber compressive force. For switchgrass, pickup design and blockage resistance are the primary selection criteria; for miscanthus, gearbox torque rating, chain specification, and roller compressive force are more critical. The 9YG-2.24D Transcend addresses all of these dimensions simultaneously through its dual-coupling high-torque gearbox and dual-side 20A chain chamber drive, making it the most versatile choice for an operation handling both crops.<\/p>\n<\/div>\n<\/details>\n

\nQ5. What is the energy value per round bale of miscanthus and how does bale density affect the economics of the Korean RPS biomass supply chain?<\/summary>\n
\n

A miscanthus bale from the 9YG-2.24D chamber (\u00d81300\u00d71400 mm) at 150 kg\/m\u00b3 density contains approximately 1.86 m\u00b3 of material, weighing roughly 280 kg. At 15% moisture content and a net calorific value of approximately 16 MJ\/kg, each bale represents approximately 4.5 GJ of thermal energy. Transport cost in a biomass supply chain is typically charged per truck movement rather than per GJ, so higher bale density directly reduces the number of movements needed to deliver a given energy quantity. For Korean RPS supply contracts where transport costs are borne by the grower or aggregator, maximizing bale density through consistent sensor-controlled operation is one of the most direct levers for improving supply chain margin.<\/p>\n<\/div>\n<\/details>\n

\nQ6. Which round baler manufacturer provides RDA-certified models suitable for Korean miscanthus cultivation incentive programs?<\/summary>\n
\n

The 9YG series round balers are manufactured under ISO 9001 quality management certification, which forms the quality management documentation foundation for RDA type-approval applications in Korea. For growers participating in national miscanthus cultivation incentive programs and seeking machinery eligible for the agricultural machinery purchase subsidy, we recommend confirming the specific certification status of your chosen model at the time of purchase inquiry. Providing the intended use case \u2014 including energy crop type, annual harvest area, and tractor specifications \u2014 helps the export team advise on the most relevant model and its current regulatory status in Korea.<\/p>\n<\/div>\n<\/details>\n

\nQ7. How does a small round baler compare to a full-size model for a pilot switchgrass energy crop project on a Korean farm?<\/summary>\n
\n

For a pilot switchgrass project on 5\u201320 hectares, a smaller model such as the 9YG-1.25A provides a lower capital entry point while still delivering the sensor-controlled density management and net wrap features needed for biomass supply contract quality compliance. Its 540\u20131000 r\/min PTO flexibility makes it compatible with a wider range of existing tractor equipment on Korean farms, reducing the risk that a new round baler requires a tractor upgrade. The 9YG-1.25A produces bales of \u00d81300\u00d71250 mm \u2014 slightly smaller than the full 9YG-2.24D format \u2014 but the density consistency is comparable, and the smaller bale weight may actually be advantageous for small-scale logistics before an on-site bale handling system has been established.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<\/div>\n
