EP-4965×2640×1750 mm (L×W×H) 1900 mm Picking Width Square Baler

The 36.8–73.5 kW power range covers a broad spectrum of mid-range farm tractors — from compact 50 hp units to standard 100 hp field tractors. Farms operating in South Korea, Mongolia, Russia, and Belarus can deploy this square baler without a dedicated high-horsepower purchase, making it a practical starting point for operations transitioning from manual straw collection.

The 1900 mm spring tooth pickup reel lifts windrows cleanly from flat, level ground without stone damage — an important characteristic for Korean paddy fields and Mongolian flatland operations where buried stones are uncommon but surface hardness varies. Spring teeth absorb impact better than rigid tines and maintain pickup efficiency in light or lodged crop conditions.

The plunger compression system produces bales at densities that significantly outperform manual bundling and net-wrapped round bale alternatives on a per-unit-volume basis. High-density small square bales of hay or straw stack tightly in barn bays, fit standard container dimensions for export, and resist moisture infiltration during outdoor storage — three qualities that directly support the traded hay and biomass markets in Korea and East Asia.

Fully automatic rope baling eliminates manual twine threading between bales. The timing mechanism triggers twine needles and D-type knotters at consistent density points, maintaining knot integrity across varied crop moistures — from dry cereal straw in summer to slightly damp alfalfa in autumn. Consistent knots mean fewer broken bales during mechanical loading and transport.

Designed to operate on both paddy field terrain and conventional dryland soils, the 9YF-1900 handles the surface-condition variability that single-crop balers struggle with. Its mid-mounted balance and trailing running gear allow it to follow irregular field surfaces without the frame stress that front-mounted square balers experience on Korean upland plots with cross-slope headlands.

Welded Steel Main Frame

The main chassis is fabricated from heavy-section hot-rolled steel sections, fully welded and gussetted at all load-bearing nodes. The frame must absorb the repeated impact loads generated each time the plunger reaches bottom-of-stroke compression — forces that accumulate to millions of cycles over a machine's field life. Frame geometry is verified by finite-element analysis to eliminate fatigue cracking at the highest-stress welds around the plunger housing.

Plunger & Chamber Liners

The plunger face and compression chamber walls are lined with hardened wear-plate steel. Replaceable wear inserts at the plunger corners and chamber entry points extend service intervals without requiring full plunger or chamber replacement. Consistent chamber geometry across the wear life of the liners maintains bale density and shape — essential when producing small square bales of hay for the Korean export and livestock feed markets where bale dimension uniformity is a commercial requirement.

Spring Tooth Pickup Reel

Individual spring teeth are formed from oil-tempered spring steel and are individually bolted to the pickup reel tube — allowing single-tooth replacement after stone strike damage without removing the full reel assembly. This field-serviceability feature is significant for Korean paddy-to-dryland operations where stone contamination risk varies by field history.

D-Type Knotter Assembly

Precision-machined alloy steel bill hooks with surface-hardened bearing surfaces. The knotter timing is fixed to the plunger crankshaft through a positive-drive chain, ensuring correct bill hook position relative to plunger position across the full power and speed range — preventing the timing drift that causes missed knots during heavy crop loading at the upper end of the 73.5 kW power range.

South Korea

The Act on Promotion of Agricultural Mechanisation governs the import and use of farm machinery. The Rural Development Administration (RDA) operates a voluntary performance certification programme for imported agricultural equipment; RDA-certified machines are eligible for government purchase subsidies targeted at small and medium-scale Korean farms. Importers should request full Korean-language operator manuals and parts lists to support RDA registration documentation. PTO shaft guarding must meet the minimum shielding requirements applicable under Korean industrial safety law.

European Union

Trailed agricultural machinery marketed in EU member states must carry CE marking in accordance with Machinery Directive 2006/42/EC. This directive is being replaced by EU Machinery Regulation 2023/1230, which will apply from January 2027. ISO 11684 applies to safety sign requirements. Square balers specifically require guard documentation for the flywheel, PTO shaft, and knotter zone under Annex I of the directive. Manufacturers must maintain a Technical Construction File for inspection by market surveillance authorities.

Russia & EAEU

Machinery sold into the Eurasian Economic Union — covering Russia, Kazakhstan, Belarus, Armenia, and Kyrgyzstan — must carry EAC (Евразийское соответствие) conformity marking under Technical Regulation TR CU 010/2011 on machinery safety. Agricultural machinery is explicitly covered and requires third-party conformity assessment by an accredited EAEU certification body. Documentation must be submitted in Russian. Importers operating in Belarus are subject to the same EAEU framework as Russia.

Mongolia

The General Authority for Standardisation and Metrology (MASM) manages import certification for agricultural equipment in Mongolia. Machines above a set output threshold require a technical inspection certificate at the point of customs clearance. Mongolian buyers typically request Chinese or English documentation; importers should confirm that operator manuals, spare-parts lists, and lubrication schedules are available in a language accessible to local service technicians before confirming the order.

Rice & Wheat Straw — Korea & Japan

Post-combine straw collection on Korean and Japanese cereal farms is one of the most time-critical agricultural operations of the year — the baling window between combine exit and field re-entry for tillage or seeding can be as short as five days in wet autumn conditions. The 9YF-1900's 1900 mm pickup width handles the wide windrows left by modern wide-cut combines efficiently, and the compact 4965 mm overall length fits on the narrow headlands typical of Korean paddy field blocks. The resulting small square hay bales can be sold directly to local mushroom cultivation, biomass, or livestock bedding markets without further processing.

Forage Grass & Alfalfa — Mongolia

Mongolian livestock producers cutting and baling native grassland or cultivated alfalfa for winter fodder require bales with sufficient density to survive outdoor stacking under snow load for four to six months. The 9YF-1900's plunger compression consistently achieves bale densities that resist settling and shape loss during this storage period. Square hay bales also stack into stable columns that reduce feed loss due to mould penetration from rain ingress — a practical advantage in Mongolian steppe conditions where covered barn storage is often insufficient for the full winter feed inventory.

Cotton & Corn Stover — Russia & Central Asia

Cotton straw and corn stover baling in Russian and Central Asian agricultural regions requires a feeder and compression system capable of handling the coarser, stiffer fibre structures of these crops compared to cereal straw. The fork feeding mechanism on the 9YF-1900 pre-compresses and meters these materials into the chamber in controlled charges, preventing the bridging and blockages that cause unplanned field stoppages during the narrow autumn harvest window. The resulting bales are used in bioenergy feedstock supply chains and as livestock roughage supplements in mixed farming systems.

Contract Baling Services

The 9YF-1900's compatibility with a wide tractor power range makes it well-suited to contract baling businesses serving multiple farm clients with different tractor models. A contractor in Korea's Gyeongnam province, for example, can operate this square baler behind a 50 hp compact tractor on small paddy plots in the morning and switch to a 90 hp row-crop tractor for larger dryland fields in the afternoon without changing the baler. This flexibility reduces equipment idle time and broadens the range of clients a single machine can serve.

PTO Shaft for Square Balers

The connection between your tractor and the 9YF-1900 gearbox is only as reliable as the PTO shaft bridging them. An improperly rated shaft can fail under peak torque during dense-crop plunger cycles; an unguarded shaft creates a hazardous entanglement zone that violates machinery safety requirements in Korea, the EU, and the EAEU. Our PTO Shaft for Square Balers series is rated and shielded to match the 9YF-1900's power window, with CE-compliant guarding for export markets and EAEU documentation for Russia and Belarus. Every shaft is load-tested before dispatch.

Square Baler Gearbox

The gearbox distributes PTO power to the plunger, knotter cam, and feeder simultaneously — it is the mechanical nucleus of the entire baling cycle. A gearbox not matched to the 9YF-1900's plunger stroke frequency and peak torque requirements will suffer premature bearing and gear wear, shortening overhaul intervals and increasing downtime during the harvest season. Our square baler gearbox replacements are manufactured to the same load specifications as the original factory fitment, maintaining correct timing between the plunger, needles, and knotters after installation.
