EP-5700×2800×1780mm LWH Spring Tooth Square Baler

What Makes This Square Baler Different

The EP spring tooth square baler is a towed-type, mid-mounted machine designed for commercial and large-scale post-harvest residue collection. With a 2200mm picking width and a D-type knotter system equipped with 2 knotters, it processes material efficiently across wide swaths in a single pass — reducing labor hours and fuel expenditure significantly compared to older-generation small square balers.

The spring tooth pickup mechanism is the core differentiator. Unlike rigid finger-type pickers, the spring tooth design flexes to follow ground contours, reducing crop loss on uneven terrain and ensuring a clean, complete pickup of lodged or windrow-spread material. Whether you are baling rice straw in Korea's lowland paddies, wheat stubble in Russia's broad plains, or forage grass in the grasslands of Inner Mongolia, this machine handles varying crop conditions with consistent performance.

The fork feeding mechanism pushes material into the compression chamber evenly, minimizing blockages that can stall operations during high-throughput harvest windows. The automatic rope baling system further reduces manual intervention, letting operators focus on driving lines rather than monitoring knotter action.

① Pickup

The spring tooth pickup reel rotates forward, lifting cut crop material from the ground surface or windrow into the machine's feed channel. The spring tooth fingers flex over irregularities in the soil surface, ensuring minimal crop is left behind even on settled or compacted ground.

② Fork Feeding

Gathered material passes through the fork feeding mechanism, which packs the crop evenly into the compression inlet. This stage prevents bridging and uneven packing — a common cause of bale density inconsistency in older-generation hay baler machines.

③ Compression

The plunger drives material into the 460×360mm compression chamber. Each stroke compresses successive flakes of crop into a growing bale. The chamber geometry produces dense, stable bales suitable for long-haul transport — making them significantly more cost-efficient to move than loosely formed material.

④ Knotting & Ejection

When the bale reaches target length, the dual D-type knotters tie twine automatically around the bale. The finished square hay bale is then ejected rearward onto the field. An operator can collect, stack, or load bales without stopping the machine for tying — maximizing throughput during compressed harvest windows.

Wide-Swath Efficiency

At 2200mm picking width, this large square baler clears more ground per tractor pass than many small square baler alternatives. For large-scale operations baling hundreds of acres in a single harvest window, fewer passes translates directly into lower diesel consumption and reduced field compaction from repeated tractor traffic.

Spring Tooth Pickup Reliability

The spring tooth pickup design outperforms rigid-tine systems in wet or irregular field conditions — a critical advantage in paddy regions across East and Southeast Asia where field surfaces are rarely perfectly level after harvest. Fewer missed stems means higher bale yield per hectare.

High-Density Square Bales

The 460×360mm compression chamber produces rectangular square hay bales with high volumetric density. Unlike round bales, square bales stack flat, allowing more material per truck or rail car — a meaningful logistics advantage for straw recycling businesses and biomass fuel operations.

Automatic Rope Baling

Manual twine tying is eliminated. The automatic rope baling system fires the dual D-type knotters without operator input, removing a major source of stoppages and inconsistent bale quality. This is especially valuable when running the machine with a single operator over long shifts.

Broad Tractor Compatibility

Requiring ≥36.8kW (approximately 50hp), this square baler for compact tractor and mid-size utility tractor pairing gives farms flexibility. It does not require large row-crop tractors, making it accessible to operations running 50–80hp machines — a common configuration among Korean and Eastern European grain farms.

Main Frame

Heavy-section welded steel box beam construction. The chassis resists torsional loads from high-output compression strokes without flexing or cracking at weld joints — a common failure mode in underbuilt competing models.

拾音器

High-carbon spring steel tines, heat-treated for fatigue resistance. Spring tooth geometry provides consistent ground clearance across uneven paddy field surfaces while maintaining pickup efficiency through an entire working season.

Compression Chamber

Hardened wear-plate lining on compression surfaces. The 460×360mm chamber section is dimensionally matched to standard bale-handling equipment globally, ensuring bales produced here integrate directly into existing storage and transport infrastructure.

Drivetrain Components

PTO-driven gear train with forged and heat-treated gears throughout. Sealed bearing units on all rotating assemblies reduce lubrication intervals and extend component life in dusty or high-humidity harvest environments.

🌾 Wheat & Rice Straw Recovery

After grain combine harvest, residual straw is the most common baling application globally. This machine handles both the dense, short-stemmed straw typical of Asian paddy varieties and the longer, coarser straw from temperate wheat varieties in Eastern Europe and Central Asia.

🌽 Corn Stover Baling

Corn stover presents a challenge for many small square hay balers due to its volume and stem thickness. The spring tooth pickup and fork feeding mechanism on this machine handle bulkier stover material without the jamming events that plague lower-capacity baler designs.

🌿 Cotton Stalk Collection

Cotton stalks, often left standing or knocked over after mechanical defoliation, require a robust pickup mechanism. The spring tooth system's flexible ground-following action lifts cotton material reliably across the variable surface conditions common in drip-irrigated cotton fields.

🐄 Livestock Feed Preparation

Operations producing square hay bales for dairy or beef cattle benefit from the dense, uniformly shaped bales this machine produces. Square bales stack efficiently in feed storage buildings and are easier to portion than large round bales — a practical advantage for smaller livestock operations managing daily feed allocation.

♻️ Biomass & Straw Recycling

Biomass energy companies and mushroom substrate producers require large volumes of uniformly sized bales for logistics and processing line compatibility. The consistent 460×360mm bale cross-section from this machine integrates directly into automated biomass handling systems, reducing pre-processing costs.

South Korea (KS B ISO Standards)

Korean agricultural machinery must comply with KS B ISO 11684 for safety signs and KS B ISO 4254 for agricultural machinery general safety. PTO-driven implements are additionally governed by KS B 6024 guarding requirements. Operators in Korea are advised to verify PTO shaft guard compliance before field deployment.

European Union (CE / Machinery Directive 2006/42/EC)

For distribution within EU member states including the Netherlands and Germany, towed agricultural machinery falls under the Machinery Directive 2006/42/EC. CE marking requires documented risk assessment, conformity of PTO shielding to EN 1152, and maintenance of a technical file. Buyers in EU markets should request CE declaration of conformity documentation prior to import.

Russia & Belarus (EAEU TR)

Within the Eurasian Economic Union, agricultural machinery must comply with TR EAEU 010/2011 on machine safety and TR EAEU 018/2011 on wheeled vehicle safety where applicable. GOST R certification may also be required in Russia for commercial sales. Buyers in these markets should work with their local customs agent to confirm current documentation requirements.

General PTO Safety (ISO 500)

Regardless of destination market, ISO 500 specifies PTO shaft dimensions and rotational speed standards (540 rpm / 1000 rpm) for compatibility between tractors and implements. This square baler is designed for standard 540rpm PTO operation, consistent with the ≥36.8kW tractor power requirement. Always ensure PTO shaft guards are intact before engagement.

Square Baler Gearbox

The gearbox is the mechanical heart of any square baler. Worn or incompatible gearboxes are one of the leading causes of mid-season breakdowns. Our matched square baler gearbox units are manufactured to the same dimensional specifications as the drivetrain in this machine — ensuring direct-fit replacement without shimming or adaptation work. Stocking a spare gearbox eliminates the multi-day lead time that can cost you an entire harvest window.

PTO Drive Shaft

A correctly rated PTO shaft is not optional equipment — it is a safety-critical component. Mismatched or worn PTO shafts can fail under the high torque loads generated during peak compression cycles, creating hazardous conditions for the operator and bystanders. Our EP PTO Shaft for square balers is rated for the torque output of tractors in the 37–75kW range, with overload slip clutch protection as standard. Available in custom lengths to suit your tractor-baler hitch distance.

Our team is made up of engineers, working farmers, and field service technicians — people who understand post-harvest residue management from direct experience, not from product literature. When a knotter jams at 7pm in the middle of harvest, they know what that costs.

Founded in 2021, we started in a 2,000-square-meter workshop producing a modest volume of baling machines each year. Honest machines at fair value, backed by people who could actually diagnose problems in the field. Word spread — particularly in Mongolia, Russia, and Belarus, where durable, serviceable equipment that can be repaired with standard tools is not a preference but a requirement.

Today we operate from a 32,000-square-meter modern production facility, with annual output approaching 2,000 units. The core commitment has not changed: every square baler that leaves this facility is checked by people who have spent time baling in real field conditions — not just running factory acceptance tests.
