EP Round Baler -Φ1220 mm Compression 4100×2900×2400 mm (L×W×H)

The integrated handheld colour touch screen communicates with a high-precision displacement sensor to monitor bale diameter in real time and trigger the net wrapping sequence at the exact programmed diameter. This removes the guesswork from bale size management — every hay round bale ejected by this machine is consistent in diameter, weight, and density regardless of crop variation or operator experience level. The touchscreen interface also displays live operational data including current bale progress, wrap counter, and system alerts, keeping the tractor operator fully informed without leaving the cab. This level of digital integration is increasingly expected by commercial operations managing multiple machines across large acreages.

The continuous screw feeding mechanism on this round baler is engineered to maintain a constant, metered flow of crop into the 1400 mm wide compression chamber without the stop-start interruptions that interrupt belt or fork-only feeder systems. In dense ryegrass, thick lucerne, or tall maize residue, where conventional feeders frequently bridge and clog, the screw conveyor's positive displacement action keeps material moving regardless of windrow density variation. Commercial baling contractors operating this agricultural round baler in high-yield crop seasons — common in South Korea's autumn rice straw harvest and in Brazilian soybean stubble collection — report substantially fewer blockage-related stoppages than with earlier-generation machines.

Manual greasing of a round baler machine of this complexity — 18 pressing rollers, pickup reel bearings, feeder shaft journals, chain drive tensioners, and tailgate hinges — would consume 30–45 minutes per day and is frequently skipped under harvest pressure, leading to accelerated bearing wear and unplanned breakdowns. The fully automatic thin oil lubrication system on this machine delivers precisely metered lubricant to all chain drive components on a programmed schedule, while dry-sump grease points use a centralised manifold supply that reduces individual zerking from dozens of points to a single fill location. This extends service intervals and protects round baler parts that are expensive and time-consuming to replace mid-season.

The hydraulic system on this round baler adjusts pickup height dynamically, providing a floating action that keeps the spring tooth tines at the correct ground clearance as the machine traverses uneven terrain, furrows, and headland transitions. Without this feature, the pickup either scalps the soil surface — damaging tines and contaminating bales with soil — or rides too high and leaves crop behind on irregular ground. Floating pickup adjustment is particularly valuable in paddocks with irrigation channels, Korean terraced rice fields (계단식 논), and Dutch polders where the field surface is rarely perfectly planar. The hydraulic adjustment also makes pre-season setup faster and more precise than manual mechanical stops.

The drive shaft, bearings, clutch, chain drive, and electronic control system on this machine are sourced from internationally recognised OEM suppliers. This matters for buyers in markets where the supply of generic replacement parts is unreliable or where machinery warranty claims require documented component traceability. Using branded bearings and clutch components also means that when parts do eventually need replacement, the specifications are publicly available and the components are stocked by agricultural engineering suppliers in South Korea, Australia, the Netherlands, Brazil, Canada, and Colombia — shortening the supply chain and reducing the risk of extended downtime waiting for obscure proprietary parts.

The 2200 mm spring tooth pickup reel, riding at hydraulically controlled floating height, sweeps a wide path ahead of the machine. Spring tines lift windrow material cleanly from the ground and transfer it rearward. The hydraulic float adapts to surface undulation in real time without operator adjustment during the pass.

The continuous screw feeding mechanism receives crop from the pickup and meters it into the compression chamber at a controlled rate regardless of windrow density variation. Dense sections of the windrow do not create a surge that can jam the intake; instead, the screw geometry disperses the excess material uniformly across the 1400 mm chamber width.

Eighteen Φ222 mm pressing rollers grip and rotate incoming crop, building the bale radially from the centre outward. As the bale grows in diameter, the high-precision displacement sensor tracks its progression toward the Φ1220 mm target and transmits live data to the touchscreen display in the tractor cab.

When the displacement sensor confirms Φ1220 mm has been reached, the touchscreen alerts the operator and initiates the automatic net wrapping sequence. The programmed number of net passes is applied at consistent tension across the full bale width, and the high-precision sensor monitors net wrap loop count to ensure every bale receives exactly the correct coverage.

After the final wrap pass, the automatic cutter severs the net cleanly and the free end is guided against the bale surface. The wrapping system then resets to the standby position, ready for the next bale cycle. The full wrapping and cutting sequence is completed in under 25 seconds.

The rear tailgate opens under hydraulic control and the completed hay round bale rolls to the ground. The tailgate closes as the tractor moves forward and the next bale begins accumulating immediately. The automatic lubrication system delivers its next scheduled dose to chain drive components in the background throughout each cycle.

Australian hay exporters shipping to markets in Southeast Asia and the Middle East routinely bale at Φ1200–1250 mm diameter because the bale density and weight utilise container space more efficiently than smaller round formats. This round hay baler produces bales in exactly that size class, with the consistent Φ1220 mm diameter that container loading plans require for uniform layer stacking. The automatic net wrapping with sensor-controlled loop counts ensures every bale in a shipping container is wrapped to the same standard — a requirement when end customers in Japan and South Korea pay a premium for verified hay quality and presentation.

South Korean agricultural cooperatives (농업협동조합) operating shared machinery services increasingly invest in commercial-scale round balers to provide cost-effective baling services across multiple member farms during compressed harvest windows. The 2200 mm picking width and intelligent touchscreen control on this agricultural round baler allow a single skilled operator to service significantly more member farms per day than is achievable with smaller machines. The consistent bale weight output — monitored by the high-precision displacement sensor — also simplifies the co-operative's billing calculation when charging members per tonne of baled material rather than per bale. Korean target regions include 충남 (Chungnam), 전남 (Jeonnam), and 경북 (Gyeongbuk) grain and forage belts.

The purpose of a round baler in intensive dairy silage systems is to process cut grass into sealed, fermentable bales fast enough to keep pace with the mower and to maintain optimal harvest moisture for silage quality. At 110–150 kW, this round baler machine matches the tractor sizes deployed on large European and Korean dairy farms and runs fast enough to avoid crop wilting delays at the critical cutting stage. The Φ1220 mm bale format holds a significant quantity of high-moisture silage per bale, reducing the total number of individual film-wrapping events needed per hectare — the film wrapping step is typically the rate-limiting factor in silage bale production, so minimising bale count directly speeds the overall operation.

What is a baler used for in industrial biomass contexts? At this scale, it is a critical first step in a supply chain that converts agricultural residues into renewable energy feedstocks, animal bedding, or specialty materials. Rice straw collected in South Korea's autumn harvest window, wheat and barley straw from Australian grain farms, sugarcane tops from Brazilian operations, and energy grass from Dutch marginal land all become commercially viable biomass feedstocks when the collection and transport step is this efficient. The Φ1220 mm bale format is compatible with most industrial bale shredders and pre-processors used at biogas and pellet manufacturing plants, making this machine a natural fit for contracted residue supply agreements.

Contract baling businesses in the Netherlands (Flevoland, Friesland), Canada (Saskatchewan, Alberta), Colombia (Llanos Orientales), and Brazil (Mato Grosso do Sul) charge per bale or per hectare and depend on machine productivity to generate the margins that justify the capital cost of premium equipment. The digital control system on this round baler allows easy job logging — bale count and estimated weight per farm — which simplifies invoicing and provides data for the contractor's seasonal production records. Combined with the automatic lubrication system's downtime reduction, this machine delivers the field efficiency and management data that serious commercial operators require. This is not a machine you buy to bale a few paddocks; it is one you buy when baling is a core business activity.

The Agricultural Mechanization Promotion Act (농업기계화 촉진법) governs safety testing and approval of agricultural machinery including large round balers. The Rural Development Administration (농촌진흥청) administers performance evaluation programmes that Korean buyers use as a reference for purchasing decisions. At 2900 mm working width, road transport in Korea requires an overwidth permit under the Road Traffic Act (도로교통법); the standard non-permit road width limit is 2.5 m. The round baler gearbox and PTO driveline must comply with Korean Industrial Standards (KS B) for mechanical transmission components, and PTO guarding must meet the Agricultural Machinery Safety Management Regulations' dimensional and material requirements.

EU Machinery Directive 2006/42/EC (transitioning to Machinery Regulation EU 2023/1230 from January 2027) mandates CE marking, Declaration of Conformity, and a full technical construction file. EN ISO 4254-1 (agricultural machinery safety — general requirements) and EN ISO 11684 (safety signs) both apply. Whole Vehicle Type Approval under Regulation EU 167/2013 is required for trailed machinery above standard transport width on public roads in the Netherlands, Germany, Belgium, and France. The round baler gearbox falls under the Ecodesign Regulation for energy-related products if its lubricant sump exceeds the applicable volume threshold in Commission Regulation (EU) 2019/1781. Dutch buyers in Noord-Holland and Flevoland should confirm regional road transport permit procedures with their provincial authority (provincie).

Safe Work Australia's Model Code of Practice for Managing the Risks of Plant in the Workplace and corresponding state WHS Act regulations cover guarding, PTO safety, and operator exclusion zones during baling operations. At 2900 mm, this machine exceeds the standard 2.5 m road width limit in all Australian states, requiring an Oversize and Overmass (OSOM) permit and potentially a pilot vehicle depending on state and route. Queensland Transport and Main Roads and Victoria's VicRoads have specific escort requirements for agricultural machinery above 3 m; buyers should confirm transport arrangements before delivery. Agricultural show and demonstration permits are separate and handled through state agriculture departments.

INMETRO Resolution 488/2021 and ABNT NBR standards govern agricultural machinery conformity assessment in Brazil. At this machine weight and power class, a Technical Evaluation Report (Laudo Técnico de Avaliação) from an INMETRO-accredited body is likely required. MAPA (Ministério da Agricultura, Pecuária e Abastecimento) handles import registration for agricultural equipment, and the gearbox and PTO shaft components must comply with relevant ABNT NBR standards for mechanical transmission safety. Brazilian state road authorities (DENATRAN) apply width restrictions of 2.6 m for agricultural machinery on state highways; special transport authorisation (Autorização Especial de Trânsito) is required for widths exceeding this limit, which applies to this machine.

Canadian Agricultural Safety Association (CASA) guidelines and provincial OHS regulations govern machinery safety standards for agricultural equipment. Alberta OHS Code Chapter 18, Ontario Regulation 851, and Saskatchewan's Occupational Health and Safety Regulations all include provisions for machinery guarding and PTO shaft protection relevant to this machine. At 2900 mm transport width, special transport permits are required in all provinces — standard non-permit width is 2.6 m in most provinces. Saskatchewan Highway Traffic Act and Alberta Transportation regulations set specific procedures for agricultural machinery overwidth transit. Buyers in the Canadian Prairies should confirm permit procedures with their provincial ministry of transportation before delivery is finalised.

Colombia's Ministry of Transport (Ministerio de Transporte) requires prior route authorisation for oversize loads on national highways. ICONTEC NTC 4116 sets safety sign and guarding requirements for agricultural machinery placed on the Colombian market. The Andean Community's harmonised technical regulations (Decisión 562 de la Comunidad Andina) also cover machinery safety labelling and are directly applicable. Key Colombian agricultural regions where this round baler application is growing include Córdoba, Sucre, and Meta, where expanding cattle and forage industries are driving demand for commercial hay baling capacity beyond what smaller machines can supply. Buyers should consult AGROSAVIA (Colombia's agricultural research agency) for current machinery import guidance.

The internal round baler gearbox transmits power from the PTO input to the pickup reel drive, screw feeding mechanism, 18 compression rollers, and automatic net wrap unit simultaneously. At 110–150 kW input, the gearbox must handle sustained torque loads that significantly exceed those of smaller-format machines. Our matched gearboxes for this model use case-hardened helical gears in a ductile iron housing with a heat-dissipating ribbed exterior, suitable for continuous high-load operation across full commercial working days. Oil specification, fill volume, and service interval are clearly documented in the technical manual provided with each machine.

The PTO shaft connecting a 110–150 kW tractor to this round baler must be rated for peak torque inputs above 3000 Nm at 540 or 1000 rpm PTO speed. An undersized or worn shaft is a safety risk and a leading cause of drivetrain damage in commercial baling operations. Our matched PTO shafts for this application incorporate wide-angle constant-velocity joints that accommodate the full range of tractor-to-baler angular positions, an overrun clutch for baler protection during sudden stops, a shear bolt torque limiter for pickup protection, and full-length CE-compliant PTO guarding. Specify your tractor model and drawbar-to-PTO-output distance when ordering to receive the correct shaft length.
