EP-5600×2780×1790mm (L×W×H) Spring Tooth Type Double-Chamber Square Baler

01 — DOUBLE-CHAMBER OUTPUT

Twin 460×360mm compression chambers operating in parallel from a single tractor pass is the defining commercial advantage of this square baler machine. Where a conventional single-chamber large square baler produces one bale per cycle, this model produces two — effectively doubling per-hour bale output from the same tractor, fuel, and operator investment. For commercial hay contractors in Australia and Canada billing by the bale or by the paddock, this output multiplier directly improves the return on every field hour worked during peak season.

02 — SPRING TOOTH PICKUP

The 2200mm wide Spring Tooth Type (弹齿式) pickup is well-proven across a wide range of crop types and field conditions. Spring tines flex on ground contact rather than breaking, extending their service life through multi-season use and reducing round baler parts replacement frequency. The generous 2200mm pickup width covers the full windrow width left by most twin-blade mower conditioners and wide rotary rakes, minimising the need for windrow merging passes and keeping total field operations per cut to a minimum — a time and cost saving that accumulates across a full baling season.

03 — 2×2 D-TYPE DUAL KNOTTERS

Four D-type knotters in a 2×2 configuration — two per chamber — apply two rope ties to every bale from each chamber simultaneously, producing structurally robust square hay bales that resist breakage through mechanical handling, transport, and storage. The D-type knotter is a well-established design format with a long service record on commercial square hay baler machines across Europe, North America, and Asia-Pacific, offering consistent tie formation across standard sisal and synthetic baler twine grades available through dealer networks worldwide.

04 — COMPACT MACHINE FOOTPRINT

At 5600×2780×1790mm overall dimensions and 3115 kg, this double-chamber square baler maintains a more manageable transport envelope than many large square baler designs producing equivalent output. The lower machine height of 1790mm is particularly relevant for road transport under bridges and overhead power lines on farm laneways — a practical consideration for contractors moving between multiple farm clients across hilly or infrastructure-dense regions in Korea, the Netherlands, and the UK. Compact dimensions also simplify implement shed storage between seasons.

05 — BROAD POWER COMPATIBILITY

A matching power requirement of ≥51.5 kW (≥69 HP) is notably accessible for a double-chamber large square baler with this output capacity. This means the machine can be deployed on tractors already working on many mixed farms without requiring a dedicated high-powered tractor purchase, keeping total cost of ownership lower than comparable double-bale output configurations requiring 90 HP or more. The square baler for compact tractor market segment will find this power threshold within reach of many modern utility and compact utility tractors, expanding the addressable farm size for this machine type.

Commercial Hay Contracting

Agricultural contractors in Korea, Australia, and Canada rely on bale output per day as the primary revenue driver. A double-chamber square baler machine that produces two bale streams simultaneously from the same tractor pass effectively lowers the per-bale time cost of baling without doubling tractor or fuel expenditure. For contractors running tight schedules across multiple farm clients during the short hay harvest window, this throughput advantage can translate to fitting one additional farm into the daily schedule — a meaningful revenue impact compounded across a full season.

Wheat & Rice Straw Recovery

Post-harvest wheat and rice straw recovery in South Korea, Japan, and Southeast Asia operates under tight time constraints — the stubble field must be cleared for next crop establishment within days of grain harvest. The EP's 2200mm spring tooth pickup efficiently lifts and clears the straw windrow in a single pass, and the double-chamber output ensures the available baling hours between grain harvest and the next sowing deadline are used at maximum productivity. Small square bales of hay and straw at 460×360mm cross-section are also the preferred format for mushroom substrate buyers who specify consistent bale weight and dimensions for their processing operations.

Alfalfa & Mixed Grass Hay

Spring tooth pickups are the preferred configuration for alfalfa baling because they handle the leafy, brittle nature of wilted alfalfa with lower leaf loss than hammer-claw or belt-based alternatives. The spring tines lift alfalfa cleanly from the windrow without shredding the leaf fraction that carries the bulk of the plant's protein and energy value — critical for hay destined for high-producing dairy cows or competition horses on farms across the Netherlands, Australia, and Canada where hay quality is purchased on protein and energy density analysis, not just visual grade.

Biomass & Fibre Crop Baling

Square bale format is the preferred delivery format for many biomass plant purchasing specifications, with bale weight and dimensions required to meet specific volumetric loading targets for biomass trucks and boiler feed systems. The consistent 460×360mm bale cross-section from the EP double-chamber square baler meets standard biomass purchasing specifications used across Korean and European district heating and power plant procurement programmes. Double-chamber output keeps the biomass supply chain running at the throughput rates required by industrial purchasing contracts that specify delivery volumes per day or per week.

Export Hay Production

Small square hay bales are the dominant format for hay exported in shipping containers to markets in the Middle East, Southeast Asia, and East Asia from Australian and Canadian production farms. Container stuffing efficiency for small square bales relies on consistent bale dimensions across the entire consignment — the 460×360mm format from this machine stacks tightly and fills a standard 40-foot high cube container to near-maximum volumetric capacity. Double-chamber output reduces the number of field hours needed to produce a full container load, shortening the time from cut crop to ship-ready product during the weather-sensitive export hay season.

Южная Корея

Under the Agricultural Mechanization Promotion Act, square baler machines imported for use by Korean farms or eligible for government purchase subsidies must pass RDA (Rural Development Administration) type approval testing. This covers PTO shaft guarding, hitching system structural integrity, and knotter guard completeness. The double-chamber design requires certification of the knotter guarding configuration for all four knotters as a unified system. Korean-language operator manuals are expected by dealers and end-users in the Korean market as a standard deliverable with the machine.

European Union

CE marking under EU Machinery Directive 2006/42/EC (transitioning to EU Machinery Regulation 2023/1230) is required for sale in all EU member states including the Netherlands, Germany, Belgium, and France. EN ISO 4254-7 (balers and baling presses) is the primary harmonised safety standard, covering knotter guarding, PTO connection, bale ejection safety, and rear gate design. For a double-chamber baler with four knotters, the risk assessment scope under EN ISO 4254-7 is expanded to cover all knotting system access points and guards around each chamber.

Australia

Safe Work Australia and state-level WHS regulations govern trailed agricultural machinery. PTO shaft guarding must comply with AS 1410. The machine weight of 3115 kg and 2780mm transport width require compliance with state over-dimension vehicle movement permits when transporting on public roads between farms. Queensland, New South Wales, and Victoria each have specific overwidth permit thresholds that should be checked before road transport. Operators should also note workplace noise exposure requirements under their state noise regulation where sustained baler PTO operation is involved.

Canada

Provincial WHS Acts govern farm machinery safety in Canada, with CEMA (Canadian Equipment Manufacturers Association) standards providing the recognised technical benchmark for baler safety and PTO shaft guarding. The ≥51.5 kW power requirement aligns with the lower-to-mid range of tractors commonly operated on Saskatchewan, Alberta, and Ontario grain and hay farms. Canadian buyers should also verify current import duty classification under the Canada-EU CETA agreement or the CUSMA framework, which may offer duty relief on agricultural machinery categories.

Brazil & Colombia

In Brazil, ABNT standards and MAPA Ministry of Agriculture import classification apply to agricultural machinery. INMETRO certification requirements should be confirmed per the specific machine category and intended market. In Colombia, ICA and INVIMA frameworks govern agricultural equipment imports. Both markets have growing commercial forage and biomass sectors where high-output square baler machines are finding demand, particularly among large-scale cattle ranching and sugarcane co-product operations seeking to monetise crop residue or reduce purchased feed costs.

United Kingdom

Post-Brexit UKCA marking under UK Machinery Regulations (SI 2008/1597 as amended) applies for the Great Britain market. PUWER 1998 covers employer obligations for safe use of farm equipment. The HSE publishes agricultural machinery Approved Codes of Practice that specifically address knotter guarding — relevant to the EP's four-knotter dual-chamber configuration. The 2780mm machine width requires standard overwidth movement notice in England and Wales when transporting between farm locations on public A and B roads.

Square Baler Gearbox

On a double-chamber square baler machine, the gearbox carries the combined PTO torque demand of two plunger assemblies and a wider-than-average pickup — a more demanding duty cycle than equivalent single-chamber machines. Our matched baler gearbox for the EP spring tooth platform is engineered to the specific torque and speed requirements of the dual-plunger drive layout, using case-hardened helical or bevel gear sets in an oil-bath sealed housing with oversized shaft bearings to handle the alternating plunger shock loads. For buyers in South Korea and the Netherlands requiring CE or RDA compliance documentation, we supply full gearbox technical data alongside the baler as a standard part of the export documentation package, reducing the compliance file burden for importers dealing with local machinery registration authorities.

PTO Drive Shaft

Он PTO shaft for square balers connecting the tractor to this double-chamber square baler must be rated for the combined drive loads of both compression systems operating simultaneously. Our matched EP PTO shafts include torque-limiting overrun clutch options that protect the gearbox from the peak impact loads generated when both plungers reach maximum compression simultaneously — a load condition unique to double-chamber machines that is not adequately addressed by standard single-chamber shaft ratings. Safety guarding complies with EN 12965 across EU, UK, Australian, and Canadian regulatory frameworks, and telescoping length is specified to match the EP baler hitching geometry without any field modification. All cross-and-bearing joints include grease nipple fittings at service points that align with the baler's standard maintenance schedule intervals, reducing the total number of independent service operations per season.
