EP-HC-40002 Round Baler Gearbox – 85HP Heavy Duty

★ The Heaviest-Duty Gearbox in the HC Series — 85HP, 111kg, Three Reduction Ratios, Built for Round Baler Punishment

The EP-40002 is not a general-purpose agricultural gearbox scaled up — it is a dedicated high-torque drive unit designed from the ground up for the cyclical shock loading, sustained compression, and extreme torque demands of large-format round baler operation. Three reduction ratios (3.2:1 / 3.77:1 / 4.17:1) and gear modules from M12 to M15 — the coarsest tooth pitch in the entire HC series — deliver the bending strength and surface durability that 85HP bale chamber drives require at every rotation. The 1 3/4″ Z6 spline input (a full step above the 1 3/8″ standard used on lighter units) and the Φ333mm circular flange housing at 111 किलोग्राम reflect the structural reality of this application: when a baler stalls in a heavy windrow, the drivetrain absorbs that energy somewhere — and it should be the overload clutch, not the gearbox. Supplied by Korea Ever-Power Agricultural Machinery Co., Ltd. to commercial baler manufacturers and large-scale farm operators across South Korea, Japan, and Southeast Asia.

What the EP-40002 Is — and the Problem It Solves

EP-40002 heavy duty round baler gearbox 85HP 111kg three ratio Korea Ever-Power

EP-40002 · 85HP · Ratios 3.2:1–4.17:1 · 111 kg · Φ333mm flange

Round balers operate under a load profile that no other agricultural implement replicates. Each bale cycle compresses a mass of crop from loose windrow material into a dense, tightly bound cylinder — and during that compression phase, the bale chamber resistance increases non-linearly. At peak chamber pressure, the drive system experiences torque spikes 3–5 times the average running load, delivered at unpredictable intervals depending on crop density, moisture content, and forward travel speed. A gearbox that performs adequately at average load will fail prematurely in this application because gearbox life is determined by peak loads, not mean loads.

The EP-40002 is built around this reality. The M12–M15 gear module range gives each tooth a face width and root fillet large enough to absorb repeated peak-load spikes without the progressive tooth-root cracking that develops in fine-pitch gearing under shock loading. The 111kg housing mass is not excess weight — it is the structural volume required to contain the large-module bevel gear set at the correct bearing span, maintain housing rigidity under the asymmetric forces generated during belt-wrap compression, and provide the oil sump capacity needed for sustained thermal management at 85HP.

The 1 3/4″ Z6 spline input is the most visible departure from the standard HC mower and tiller range. This larger-diameter spline transmits the peak torque that 85HP at 540RPM represents — approximately 1,190 Nm at the input shaft — with the contact area and shear strength to do so across the cyclical load variation of baler operation without spline wear that would develop on the smaller 1 3/8″ interface used in lower-power units. Buyers replacing an existing round baler gearbox should confirm their tractor and machine PTO shaft standard before ordering: the 1 3/4″ Z6 is the correct specification for large-frame balers; it is physically incompatible with the 1 3/8″ shafts used on mowers and tillers in the same HP range.

Replacement Reference: The EP-40002 is engineered to match the specification of comparable Claas, Krone, New Holland, and John Deere OEM round baler drive gearboxes in the 85HP / high-reduction-ratio class. Korea Ever-Power is not affiliated with, sponsored by, or an authorised parts supplier for these OEM brands.

Complete Technical Specifications — All Three Ratio Configurations

All parameters below are factory-verified from the official EP-40002 product datasheet. The module values listed alongside each ratio — M15, M13, M12 — represent the actual gear module for that tooth pair, not a nominal series designation. The module decrease as ratio decreases (from 4.17:1 to 3.2:1) follows the same progressive-module logic seen in the EP-75: lower ratios carry higher circumferential velocity at the tooth face, so a slightly smaller module (with higher tooth count) provides better tooth engagement smoothness while still meeting the bending strength requirement for 85HP. All three configurations share the same housing, input shaft, and output flange — only the internal gear set changes.

EP-40002 heavy duty baler gearbox circular flange housing dimensions and gear detail

Φ333mm circular flange OD · housing height approx. 339.5mm

The engineering drawing confirms the EP-40002's circular flange mounting face: Φ333mm outer diameter, Φ296.8mm pitch circle diameter for the mounting bolt holes, Φ235.6mm bore — dimensions that align with the standard bolt-circle configurations used on large-format European round baler drive assemblies. The dual 1 3/4″ Z6 spline input sockets (one each side of the housing centreline, spaced at 1 3/4 Z20 as visible in the drawing detail) allow dual-side PTO input configurations used on certain baler designs where the drive shaft approaches from either side depending on the tractor-baler connection geometry.

The housing cross-section height of approximately 339.5mm reflects the physical space required by the large-module bevel gear pair. At M15 (Config A), the crown gear pitch diameter alone exceeds 720mm — this is not a standard mower-style gearbox that happens to have a large housing. The housing geometry is specifically designed around the gear set, with bearing spans and wall thicknesses calculated to maintain the correct gear mesh contact pattern under the asymmetric loads imposed by alternating compression and release cycles during bale formation.

Three Ratio Configurations — Matching Output Speed to Your Baler Design

Round baler rotor and bale chamber designs vary in their required input shaft speed depending on bale diameter, belt wrap system, and crop type. The EP-40002's three ratio options cover the speed range used across the main large-format baler designs in production today. All three are rated at the same 85HP — the ratio selection determines output speed and torque multiplication, not power capacity.

Config A · 3.2 : 1

Highest output speed · lowest torque multiplier

दाँत	15 / 48
आउटपुट आरपीएम	≈ 169 RPM
आउटपुट टॉर्क	≈ 3,540 Nm
इनपुट	1 3/4″ Z6

Best for: balers with higher rotor speed requirement, lighter crop conditions (dry grass, straw), or faster belt-wrap systems that need the higher output RPM to maintain bale density.

Config B · 3.77 : 1

Mid-range · most commonly specified

दाँत	13 / 49
आउटपुट आरपीएम	≈ 143 RPM
आउटपुट टॉर्क	≈ 4,170 Nm
इनपुट	1 3/4″ Z6

Best for: general-purpose large round baler operation, mixed crop conditions (grass, hay, legumes), and replacement of OEM baler gearboxes where the original ratio is approximately 3.7–3.8:1.

Config C · 4.17 : 1

Highest torque · lowest output speed

दाँत	12 / 50
आउटपुट आरपीएम	≈ 129 RPM
आउटपुट टॉर्क	≈ 4,620 Nm
इनपुट	1 3/4″ Z6

Best for: dense, heavy crop conditions (corn stover, thick hay at high moisture), large-diameter bale formats, and applications requiring maximum torque multiplication to drive a stiff bale chamber.

Quick selection guide: If you are replacing an existing OEM baler gearbox, match the original ratio as closely as possible. If you are specifying for a new baler build, calculate the required rotor shaft RPM from your bale chamber design and select the config whose output RPM at 540 input is closest to that requirement. Korea Ever-Power can provide ratio confirmation support — contact us with your baler make, model, and original gearbox part number for a direct match recommendation.

Understanding Output Torque — How to Calculate What Your Application Needs

Many gearbox buyers focus on the HP rating without calculating the actual output torque that their baler drive system will experience. For a राउंड बेलर गियरबॉक्स, output torque is the number that determines whether a gearbox survives the bale-formation peak load cycle. Here is a straightforward calculation method:

Output Torque Formula

टी_out (Nm) = 9,550 × P (kW) ÷ n_out (RPM)

Where पी = rated power in kilowatts (85HP ÷ 1.341 = 63.4 kW) and एन_out = output shaft RPM at the selected ratio.

अनुपात	आउटपुट आरपीएम	आउटपुट टॉर्क	Typical baler chamber requirement
3.2 : 1	≈ 169 RPM	≈ 3,580 Nm	Light crop, dry conditions, higher rotor speed balers
3.77 : 1	≈ 143 RPM	≈ 4,230 Nm	Standard mixed crop, most commercial baler designs
4.17 : 1	≈ 129 RPM	≈ 4,690 Nm	Dense or wet crop, large bale diameter, maximum compression

To use this table in practice: determine your baler's design bale chamber torque requirement from the machine manufacturer's service manual. The EP-40002 configuration whose output torque exceeds that requirement — with at least a 25% margin for peak load spikes — is the correct specification. If your calculated requirement falls between 3,500 and 4,700 Nm at 85HP, the EP-40002 covers it across the three configurations. If it exceeds 4,700 Nm at 85HP, contact Korea Ever-Power's technical team to discuss options.

Construction Quality — Why 111kg Is Structural Necessity, Not Excess

⚖️

Large-Module Gear Mass

The bevel gear pair in Config A — 15-tooth pinion and 48-tooth crown at M15 — weighs significantly more than any gear set in the HC mower or tiller range. M15 tooth pitch means each tooth is 15mm in module, producing a gear face width and root cross-section that dominates the component weight. This gear mass cannot be reduced without reducing module — which directly reduces bending strength — so the 111kg is partly the unavoidable physical consequence of the gear specification.

🏗️

Heavy-Section GGG50 Housing

At peak bale compression, the housing experiences the full reaction torque of the output shaft — approximately 4,200–4,700 Nm in Config B/C. The housing wall thickness and rib geometry are calculated to maintain housing torsional rigidity under this load without deflection that would change the gear mesh contact pattern. Thin-wall castings adequate for mower and tiller loads would deform measurably under baler peak loads, causing the contact stress concentration that leads to progressive tooth pitting.

🔩

बड़े टेपर्ड रोलर बियरिंग

The bevel gear set at this scale requires large-bore tapered roller bearings — not the deep-groove ball bearings used in smaller units — to manage the combined radial and axial loads at the gear mesh faces. Tapered roller bearings in agricultural heavy-duty sizes carry substantial mass in their own right; they also require precision-machined seats and pre-load settings that demand the housing wall dimensions present in the EP-40002.

🛢️

High-Capacity Oil Sump

The housing volume supports a large oil charge — estimated 2.0–2.5 litres of SAE 90 gear oil based on housing dimensions. During sustained baling operation at peak output — 4+ hours of continuous heavy baling in dense crop conditions — the gear oil is the primary mechanism for removing heat from the gear mesh and bearing interfaces. The large sump volume provides the thermal buffer required to avoid oil degradation under these conditions, which would otherwise require frequent oil changes during the baling season.

⚙️

Carburised & Quench-Hardened Gear Faces

All EP-40002 gear faces are carburised to 0.8–1.2mm case depth and quench-hardened to HRC 58–62, identical to the specification used across the HC series. At M12–M15 module, carburising penetrates a proportionally smaller fraction of the tooth height than at smaller modules — the heat treatment specification accounts for this by targeting the root fillet zone where bending stress is highest, not just the tooth face where contact stress occurs.

✅

Full-Load Bench Test — Every Unit

Every EP-40002 is run at full rated load on a calibrated test bench before packaging. For a 111kg unit, this test is not trivial — it requires a test rig capable of absorbing 85HP at the output shaft while monitoring gear mesh noise, bearing temperature, oil seal integrity, and housing vibration. Units that pass this test have demonstrated their capacity under conditions that replicate baler operation, not just assembly quality.

EP-40002 vs. EP-BGB8 — Choosing Between Korea Ever-Power's Two Baler Gearboxes

Korea Ever-Power supplies two gearboxes for baling applications. The EP-BGB8 (30HP, dual-ratio, 18kg) covers the light-to-medium baler segment. The EP-40002 (85HP, three-ratio, 111kg) covers commercial-scale large baler operation. The choice is straightforward once the application is defined:

Factor	EP-40002	ईपी-बीजीबी8
मूल्यांकित शक्ति	85 HP	30 HP
इनपुट शाफ्ट	1 3/4″ Z6 (large frame)	1 3/8″ Z6 (standard)
अनुपात विकल्प	3.2:1 / 3.77:1 / 4.17:1	1:1 / 1.67:1
अधिकतम आउटपुट टॉर्क	≈ 4,690 Nm	≈ 590 Nm
शुद्ध वजन	111 kg	18 किलो
Bale Format	Large commercial round baler (≥1.2m bale diameter)	Small-medium round baler, hobby/small farm use
Choose When	Commercial farm, contractor, OEM baler manufacturer	Small farm, hobby baler, light baling duty

Do not attempt to use the EP-BGB8 (30HP, 18kg) on a machine designed for the EP-40002 (85HP, 111kg) class. The power rating difference is nearly 3:1 and the torque multiplication nearly 8:1 — a light-duty unit operated at heavy-duty loads will fail within one baling season, with potential for housing fracture and secondary machine damage.

Where the EP-40002 Is Used

EP-40002 heavy duty round baler gearbox application in large scale commercial baling operations

🌾 Large Commercial Round Balers — Korean Hay & Straw Operations

South Korea's forage hay production concentrated in Gangwon and Gyeongbuk provinces — timothy, rye grass, and Italian ryegrass for the domestic dairy and beef cattle industry — uses large-format round balers producing 1.2–1.5m diameter bales at typical throughputs of 40–80 bales per hour during peak season. The 85HP tractors operating in these conditions demand a baler gearbox rated for sustained full-load operation, not occasional peak use. The EP-40002 at Config B (3.77:1) is the standard specification for Korean large-round-baler builds targeting this market segment, where bale density requirements are high and stoppages for gearbox failure represent significant revenue loss during the narrow baling window.

🏭 OEM Baler Manufacturing — Korea & Southeast Asia

Several Korean agricultural machinery manufacturers building large round balers for domestic sale and export to Southeast Asia and the Middle East specify the EP-40002 as their OEM baler gearbox. The circular flange mounting standard (Φ333mm OD) aligns with the drive housing dimensions used in European baler designs that have been the reference point for Korean OEM engineering teams. Korea Ever-Power supplies OEM customers with confirmed matching dimensional certification, dedicated stock allocation, and volume pricing — contact our technical sales team for OEM programme details including customisation options (housing colour, shaft specifications, marking).

🌿 Rice Straw Baling — Vietnam, Thailand & Philippines

Post-harvest rice straw baling is a growing application across the Mekong Delta in Vietnam, the Chao Phraya basin in Thailand, and Luzon's central plain in the Philippines, where rice straw is processed for mushroom cultivation media, animal feed, and industrial fibre rather than burned in field. Rice straw baling at commercial scale uses large-format round balers on 80–100HP tractors. The high moisture content of freshly harvested straw (30–45% moisture at the time of field baling) significantly increases bale chamber resistance compared to dry hay, making the higher-torque EP-40002 configurations (Config C, 4.17:1) the preferred specification for operations in the wet baling conditions common to these tropical and subtropical growing regions.

🌽 Corn Stover Baling — Contract Operations

Corn stover baling for biogas feedstock and cattle bedding — a growing contract service in Korea's Gyeonggi and Chungcheong provinces — involves some of the most demanding baler drive conditions in agricultural machinery. Corn stover at harvest moisture is dense, lignin-rich, and prone to bridging in the bale chamber, creating sharp torque spikes well above the mean drive load. The EP-40002 at Config C (4.17:1, ≈4,690 Nm output torque) is specified by Korea Ever-Power's commercial contractor customers for this application — the maximum torque multiplication provides the force to overcome chamber stalls without requiring the operator to reduce forward speed below profitable throughput rates.

Large format round baler operation using EP-40002 heavy duty baler gearbox

From the Field — EP-40002 Operator Reports

Jung Byeong-chul Commercial Hay Contractor · Pyeongchang, Gangwon Province, South Korea · 2024

We run two round balers on a 90HP tractor during the June–July hay season in Pyeongchang. We were replacing European OEM gearboxes every 2–3 seasons at significant cost and 4–6 week lead times. Switched to the EP-40002 (Config B, 3.77:1) 18 months ago. We've completed one full hay season and two rounds of winter forage baling. No issues at all — the seals are dry, the oil comes out clean at 200 hours, and the noise level is comparable to the OEM unit. Lead time to Pyeongchang was 5 days. That alone saves us weeks of machine downtime risk during peak season.

Nakamura Yoshio Agricultural Machinery Dealer · Tochigi Prefecture, Japan · 2024

I supply replacement gearboxes to baler operators across Tochigi and Ibaraki — mostly large round balers on 85–100HP tractors baling grass and corn stover. The EP-40002 has become my standard recommendation for customers who don't want to wait 6 weeks for an import and don't want to pay the OEM price. I've placed three separate customer orders so far. All three machines are still running on the EP-40002 units with no reported problems. Documentation for Japanese customs was complete and correct on every shipment.

Le Van Thanh Rice Straw Baling Contractor · Tien Giang Province, Mekong Delta, Vietnam · early 2025

We operate two large balers for post-harvest rice straw baling across Tien Giang and Long An provinces. Rice straw baling is hard on gearboxes — high moisture, heavy loads, and long days. We tried the EP-40002 Config C (4.17:1) on one machine for the dry season. It handled the wet-season straw conditions at the tail end of the trial period without any sign of stress. Oil temperature stayed manageable even at 38°C ambient. I've now fitted it to the second machine as well. The price difference versus what we were paying for European parts is significant on our operating margins.

Shin Hyeon-woo Round Baler OEM Manufacturer · Gimhae Industrial Zone, South Korea · 2024

We produce large round balers for the Korean domestic market and export to Vietnam and Indonesia. We evaluated the EP-40002 against the European OEM gearbox we had been using and found the dimensional spec matches our housing design closely on Config B. The surface finish on the mounting flange face is adequate for our seal arrangement. We switched over 10 months ago and have produced 34 machines with the EP-40002. Zero gearbox-related warranty claims in that period. Korea Ever-Power's OEM support — dedicated stock allocation, technical data on request, consistent batch quality — has been what we needed.

Somphong Rattanakul Agricultural Contractor · Khon Kaen, Northeast Thailand · 2025

We bale sugarcane tops and corn stover in the northeast. Heavy work — 10-hour days, dense material, hot weather. I fitted the EP-40002 Config C to my 90HP tractor last season. It's been running for about 5 months now, probably 300 operating hours. The gearbox housing barely gets warm to the touch during operation — the OEM unit I replaced used to get quite hot. I check the oil at every 200 hours and it's consistently clean. No leaks, no noise. It has earned its place on my machine.

Frequently Asked Questions — EP-40002

Why does the EP-40002 use a 1 3/4″ Z6 input shaft when most HC series gearboxes use 1 3/8″?

85HP at 540RPM represents approximately 1,190 Nm of input torque. The 1 3/8″ Z6 spline — used on all HC mower and tiller units — has a torque capacity adequate for up to approximately 65–70HP on a standard agricultural shaft. Above that level, the spline contact stress under peak loads (which can be 2–3× the average in baler service) approaches the fatigue limit of the spline flanks. The 1 3/4″ Z6 increases the spline pitch diameter by approximately 11mm, roughly doubling the contact area and the torque capacity. Using the smaller shaft on an 85HP baler gearbox would result in progressive spline wear within the first operating season.

How do I confirm which ratio configuration matches my existing baler OEM gearbox?

The most reliable method is to count the teeth on both gears of your existing unit (if accessible for inspection) or locate the original gearbox part number in the machine service manual and check the ratio specification there. Send us the original part number or the tooth counts and we will match the EP-40002 configuration for you. Alternatively, if the original ratio is unknown, measure the output shaft RPM at 540 PTO input using a tachometer and compare to the three EP-40002 configurations (169 / 143 / 129 RPM). Contact Korea Ever-Power before ordering if you are unsure.

What gear oil volume and type does the EP-40002 require?

SAE 90 gear oil, GL-4 or GL-5 specification. Given the housing dimensions, estimated fill volume is 2.0–2.5 litres — always fill to the level mark on the oil plug, not a fixed volume. First change at 50 hours (break-in metal particles); subsequent changes every 200 hours. In continuous heavy baling service — 8+ hour operating days in dense crop — check oil temperature at 100 hours: if housing surface temperature exceeds 80°C, reduce the change interval to 150 hours and consider switching to a higher-viscosity SAE 140 or 80W-140 multi-grade gear oil for better film strength at elevated temperature.

How is the EP-40002 shipped — does the 111kg weight cause freight problems?

The EP-40002 ships by sea freight or air freight depending on order urgency and quantity. A single unit at 111kg is within LCL sea freight minimum cargo weight and can also be air-freighted as a standard heavy shipment — not dangerous goods. For Korean domestic delivery, road freight is available. Sea freight LCL to Busan (from our dispatch location) is typically 10–14 days; air freight is 3–5 days. We prepare all export documentation including commercial invoice, packing list, and Certificate of Origin. Contact us with your destination port or city for a specific freight quote alongside the product price.

Should I fit an overload clutch between the tractor PTO and the EP-40002?

Yes — for all commercial baling operations, we strongly recommend a friction torque limiter or shear-bolt overload clutch rated for 85HP between the tractor PTO shaft and the gearbox input. Round balers regularly encounter bale chamber stalls — when the bale wrapping mechanism jams, a crop slug enters the chamber, or the bale reaches density limit — and the torque spike that occurs at stall can reach 5–8× the rated running torque. Without an overload clutch, that spike is transmitted directly to the gearbox input shaft and gear set. The EP-40002 is designed for cyclical peak loads, but not for stall-condition overloads. An overload clutch is the correct safety and protection measure; it is not optional in commercial use.

Does the EP-40002 mounting flange match standard European baler designs?

The EP-40002 circular flange dimensions — Φ333mm OD, Φ296.8mm PCD, Φ235.6mm bore — are aligned with the dimensional standard used in a number of European large-format round baler drive housings. However, bolt hole count, pattern, and diameter vary between OEM designs, so direct fit cannot be assumed without verification. Korea Ever-Power can provide a dimensional drawing of the mounting flange face for comparison with your machine's housing specification. Send us your machine make, model, and year and we will confirm dimensional compatibility before you order.

What warranty applies to the EP-40002?

12 months from dispatch against manufacturing defects. Covers housing fracture under rated loads (within the 85HP specification), gear tooth failure within rated HP, bearing failure not caused by contamination or oil starvation, and seal defects present at delivery. Not covered: damage from stall-condition overloads without an overload clutch fitted, operation above 540RPM input, oil neglect, or physical damage from installation errors. We strongly recommend fitting a torque-limiting overload clutch as a precondition for warranty coverage on baler applications — stall-condition damage is not a manufacturing defect and cannot be covered regardless of the unit's age or origin. Contact Korea Ever-Power with the unit serial number and a description of any failure to initiate a claim.
