EP-4965×2500×1750mm LWH 1700mm Spring Tooth Square Baler

① Ground Pickup

The spring tooth reel sweeps forward across the windrow, lifting loose straw, grass, or crop residue cleanly from the field surface. The spring-loaded tine design is forgiving on uneven ground — a key practical advantage for paddy fields in Korea and Northern Asia where surface leveling after combine harvest is imperfect.

② Fork Feeding

Lifted material passes to the fork feeding unit, which meters crop into the compression inlet at a controlled rate. This prevents the bunching and bridging that causes compression chamber blockages — one of the most time-consuming interruptions in any baling operation, particularly when running light, fluffy straw types.

③ Plunger Compression

The plunger drives material into the 460×360mm compression chamber in successive strokes. Each stroke adds another layer to the growing bale. The chamber geometry produces square hay bales with high volumetric density — meaning fewer trips per tonne when loading, hauling, or stacking compared to loosely formed material from under-powered small square hay balers.

④ Automatic Knotting

When the bale reaches its target length, both D-type knotters fire simultaneously, tying twine around the bale without operator input. The finished bale ejects rearward onto the field. With two knotters running automatically, the operator can maintain forward speed through the entire baling cycle rather than slowing to manage tying events manually.

Wide Tractor Compatibility Range

The 29.5–73.5kW power range makes this a genuine square baler for compact tractor pairing — a 40hp utility tractor can run it, and an 80hp mid-size tractor can push it to full capacity. This flexibility reduces the barrier to entry for smaller farms while still serving commercial-scale operations running larger equipment.

Consistent Pickup on Irregular Ground

Spring tooth tines flex over clods, ridges, and soil irregularities without losing pickup contact — then spring back immediately. In fields that have not been power-harrowed after combine harvest, the spring tooth design recovers measurably more crop per hectare than rigid-tine alternatives. More straw picked up means more bales per acre and lower cost per tonne.

Stackable, Transportable Bale Format

The 460×360mm rectangular bale cross-section stacks flat and tight. When weighing how many square bales of hay fit per truck versus the dead space in round bale loads, the square format consistently delivers more payload per vehicle. For straw recycling businesses and biomass operations selling by the tonne, this makes a measurable difference in logistics cost.

No Manual Tying Intervention

Automatic rope baling removes one of the most disruptive stop-start events in traditional baling. Dual D-type knotters fire simultaneously with each completed bale, keeping the machine and tractor moving. Over a full day's operation, eliminating manual tying typically saves 45–60 minutes of downtime — meaningful productivity when harvest windows are measured in days.

Compact Machine Footprint

At 4965×2500×1750mm overall dimensions and 1750kg machine weight, this is a meaningfully lighter and shorter machine than the wider-swath models in our range. For farms with narrow gate access, terraced parcels, or transport width restrictions, the smaller footprint of this square baler machine matters at every stage — field, road, and storage.

Structural Frame

Heavy-gauge welded steel box sections form the primary chassis. The frame geometry is designed to resist torsional deflection under repeated compression plunger loads, which cycle thousands of times per operating day. Weld joint integrity is checked at multiple points in the production process.

Spring Tooth Tines

High-carbon spring steel, heat-treated for fatigue resistance. Tine geometry is tuned for the balance between flexibility and recovery speed — tines that flex too easily lose pickup efficiency; tines that are too stiff break on impact. The current specification is the result of several field iteration cycles in actual harvest conditions.

Compression Chamber Liner

Wear-resistant hardened plate on compression and bale channel surfaces. This is the highest-abrasion area of any square hay baler — the liner extends chamber service life substantially compared to unhardened steel, deferring the most costly in-field repair that operators of older baler designs commonly encounter after 500–800 hours.

PTO Drivetrain

Forged and heat-treated gears throughout the PTO drivetrain. Sealed bearing assemblies on all rotating shafts reduce daily lubrication demands and provide protection against the fine crop dust and chaff that infiltrate conventional open-bearing designs during dry harvest conditions.

🌾 Rice Straw Post-Harvest Recovery

After paddy combine harvest across Korea, Japan, and Southeast Asia, large volumes of short, fine rice straw are left in loose windrows. The spring tooth pickup on this machine handles this light material efficiently, gathering cleanly without pulling up soil or stones that would contaminate bales and damage recipient processing equipment downstream.

🌽 Corn Stover Collection

Corn stover is one of the more challenging baling crops — bulky, moisture-retaining, and prone to causing blockages in machines not designed for it. The fork feeding mechanism on this baler controls material flow into the inlet at a rate the compression chamber can process cleanly, reducing the stover-related blockages that plague general-purpose small square baler designs not built for this crop type.

🌿 Wheat Straw Baling in Temperate Zones

In the wheat belts of Russia, Belarus, and Mongolia, post-harvest straw management is a large-scale logistical challenge. This machine's 1700mm picking width covers ground efficiently enough for commercial-scale straw contractors while remaining compact enough for farms with narrower field access routes and smaller storage facilities than operations running big square balers.

🐄 Livestock Feed & Bedding

Operations producing small square hay bales for dairy or beef cattle benefit from the consistent bale dimensions this machine produces. Square bales are easier to portion for daily feed allocation than large round bales, and they stack efficiently in existing storage without specialized handling equipment — important for smallholder livestock farms managing feed stocks manually.

♻️ Biomass Fuel Supply Chains

Biomass energy plants and agricultural waste processing facilities increasingly require contracted straw supply in uniform, stackable bale formats. The square bale output from this machine — consistent cross-section, high density — integrates directly into automated biomass handling conveyors without pre-sorting or reprocessing steps that add cost and handling time.

South Korea — KS B ISO Framework

Korean agricultural machinery is governed under KS B ISO 4254 (agricultural machinery general safety) and KS B ISO 11684 (safety signs). PTO-driven towed implements must meet KS B 6024 guarding requirements. Korean buyers should confirm that PTO shaft and guard specifications match local compliance requirements before committing to a field deployment schedule.

EU — Machinery Directive 2006/42/EC

Towed agricultural implements entering EU member states require CE conformity under the Machinery Directive 2006/42/EC. PTO shaft shielding must comply with EN 1152. Buyers in Germany, the Netherlands, and other EU markets should request CE declaration of conformity documentation and verify that the supplied PTO shaft meets EN 12965 for tractor-to-implement connections before field use.

Russia & Belarus — EAEU TR Requirements

Within the Eurasian Economic Union, TR EAEU 010/2011 governs machinery safety and TR EAEU 018/2011 covers wheeled vehicle requirements where applicable. Russia additionally enforces GOST R certification for commercial agricultural equipment sales. Buyers in these markets should confirm current certification requirements with their customs agent, as documentation requirements are updated periodically.

Global PTO Standard — ISO 500

ISO 500 defines PTO shaft dimensions and rotational speed standards (540rpm and 1000rpm) that govern compatibility between tractors and PTO-driven implements worldwide. This square baler operates on standard 540rpm PTO, within the 29.5–73.5kW tractor range specified. Ensure the PTO shaft guard is intact and properly secured before every engagement — this is not optional in any jurisdiction.

Square Baler Gearbox

A failing gearbox mid-harvest is not a maintenance event — it is a production loss. Our matched square baler gearbox units are dimensionally and specification-matched to this machine's drivetrain. Direct-fit replacement means no shimming, no machining, and no time lost to sourcing parts that almost fit. Keeping a spare on hand before the season begins is the single most effective insurance against harvest disruption.

PTO Drive Shaft

The PTO shaft transmits all drivetrain torque from tractor to machine — it is the most stressed single component in the system. Undersized or worn shafts are a safety risk, particularly during the high-load compression cycles that characterize dense straw or corn stover baling. Our EP PTO Shaft for square balers is rated across the full 29.5–73.5kW tractor power range of this machine, with integrated slip-clutch overload protection. Available in custom lengths to suit different tractor-hitch configurations.

The people behind this machine are engineers who have worked farm equipment problems on actual farms, service technicians who have responded to breakdowns during harvest, and growers who understand what a failed machine at 6am costs in a narrow weather window. Post-harvest residue management is not an abstract logistics challenge for our team — it is something they have managed directly.

We started in 2021 with a 2,000-square-meter facility and a straightforward goal: build machines that work when farms need them, at price points that do not require buyers to choose between quality and financial viability. Too many operations were trapped between overpriced premium brands and underbuilt budget machines that failed precisely when the pressure was highest.

Growth has been consistent. Our production floor now covers 32,000 square meters of modern manufacturing space, and annual output has scaled from roughly 100 units to 2,000. Our machines are now working in Mongolia, Russia, Belarus, and across multiple export markets. The benchmark for everything we build remains the same: does it perform in the field under real conditions, not just in a factory acceptance test?
