Gearbox Menengah Serbaguna Ringan EP-LMP70 — Penggerak Flensa Kompak 40 hingga 70 KW

EP-LMP70 Light Multi-Purpose Gearbox — Product Overview

Built for Asia’s Small-to-Mid Farm Segment

Korea’s agricultural landscape is dominated by small-to-mid size farms where a single 55–95 HP tractor serves every task from spring paddy preparation to autumn straw management. The EP-LMP70 light multi-purpose intermediate gearbox is purpose-built for this scenario: a single, reliable gearbox kultivator putar that connects the tractor’s PTO output to any tillage or cultivation implement in the 40–70 KW power bracket.

Optimized Speed Reduction for Tillage

The 1.533 : 1 reduction ratio converts the standard 540 rpm PTO speed into 352 rpm at the output flange — a speed that precisely matches the working range for rotary tillers, soil beaters, and straw choppers. This ratio simultaneously multiplies input torque by 1.533×, providing the cutting force needed for medium-weight soil conditions without overloading the tractor’s PTO clutch or burning excessive fuel.

Entry Point in a Three-Tier Family

As the lightest member of Korea Ever-Power’s multi-purpose gearbox family — followed by the EP-MMP100 at 80–100 KW and the EP-HMP150 at 150 KW — the EP-LMP70 is designed so that any farmer can start at the light tier and upgrade to a larger gearbox as their operation grows, without changing the implement frame or driveline architecture.

Spesifikasi Teknis Lengkap

All specifications verified against the Korea Ever-Power engineering drawing for the EP-LMP70 (catalog reference P04). Dimensional values measured at 20°C ambient, no-load condition.

Multi-Purpose Series Sizing Ladder — LMP70 vs. MMP100 vs. HMP150

Korea Ever-Power’s multi-purpose gearbox family follows a three-tier sizing strategy. All three models share the same 1.533–1.54 : 1 ratio range and identical 540 rpm PTO input, but scale up in power capacity, housing size, and output spline strength. Choosing the correct tier comes down to your tractor’s PTO horsepower and the torque demands of your implements.

Compact Cylindrical Design — Why Size Matters in the Field

Ø200 mm Cylindrical Housing

Unlike rectangular gearbox housings that can catch on crop residue or field debris, the EP-LMP70’s cylindrical profile sheds material cleanly during operation. The Ø200 mm diameter and 200 mm length yield an extremely compact 6.3-liter volumetric envelope — one of the smallest in its power class. This minimizes the overhang behind the tractor’s three-point hitch, improving headland turning radius and reducing the bending moment on the implement frame.

28 kg Dry Weight

At only 28 kg without oil, the EP-LMP70 is light enough for a single operator to handle during installation or replacement. For comparison, competing gearboxes in the 60–70 KW range typically weigh 35–45 kg. This weight advantage matters on compact implements designed for small tractors, where every kilogram of parasitic weight reduces effective payload and increases fuel consumption during transport between fields.

Positive-Engagement Flanged Output

The 6-M12 bolt flange on Ø175 PCD with Ø150 spigot provides a backlash-free, self-centering connection to the implement input shaft. The spigot registers the gearbox concentrically with the implement bore before the bolts are tightened, eliminating the angular misalignment that causes premature bearing wear in keyway-connected assemblies. Bolt torque is specified at 85 N·m in a star pattern for even clamping force distribution.

Dimensi Utama & Antarmuka Pemasangan

Skenario Aplikasi Lapangan

Small-Scale Rice & Vegetable Farms

Farmers working 1–5 hectares on 55–75 HP tractors represent the largest segment of Korean agriculture. The EP-LMP70 is sized precisely for this audience — powerful enough to handle spring paddy tilling and autumn straw incorporation, light enough to keep the implement manageable in narrow paddies and polytunnel aisles. The 352 rpm output speed falls squarely in the optimal range for compact rotary tillers with working widths of 1.2–1.8 meters.

Greenhouse & Polytunnel Operations

Protected cultivation facilities in Korea and Japan often operate compact tractors in extremely tight spaces. The EP-LMP70’s cylindrical Ø200 mm housing has no protruding bolt heads or rectangular edges to snag on greenhouse structural members or plastic sheeting during turning maneuvers. The 28 kg weight ensures the three-point hitch lift capacity is not wasted on gearbox mass, leaving more payload for the implement itself.

Equipment Rental Fleets

Rental companies equipping their tiller fleets with standardized gearboxes benefit from the EP-LMP70’s CNC-machined dimensional consistency. Every unit is geometrically identical (±0.02 mm bore tolerance), so technicians can swap a failed gearbox between any machine in the fleet without shimming, re-drilling, or field alignment — minimizing equipment downtime and maximizing daily rental revenue.

Why Choose the EP-LMP70 for Your Operation

Installation & First-Run Guide

Prosedur Pemasangan

❶ Align the EP-LMP70’s Ø150 spigot with the implement’s mating bore. The spigot self-centers the gearbox concentrically before bolt tightening begins.

❷ Insert all six M12 flange bolts finger-tight, then torque to 85 N·m in a star pattern to ensure even clamping. Re-check torque after the first 8 operating hours.

❸ Hubungkan Poros penggerak PTO to the top input boss. Verify that the shaft safety guard is properly installed, free to rotate, and covers the full spline engagement length.

❹ Isi oli gir (SAE 80W-90 GL-5) melalui lubang ventilasi atas hingga oli mencapai bagian tengah kaca pengintai samping — kira-kira 1.2 liters.

First-Run Verification

Run a 5-minute idle test at low PTO speed (approximately 300 rpm). Listen for abnormal noise — a properly assembled EP-LMP70 produces a smooth, even hum with no clicking, grinding, or knocking. Verify that no oil seepage appears at the housing split line or shaft seal faces. Confirm the output flange rotates freely without catching or pulsating. Once verified, engage full PTO speed (540 rpm) and begin field operations.

Produk Pelengkap & Komponen Penggerak

Pair the EP-LMP70 with other Korea Ever-Power driveline components for a complete power transmission package:

Poros Penggerak PTO

Korea Ever-Power supplies matched cardan shafts from our drive shaft division, pre-configured for the EP-LMP70’s standard PTO input. Properly matched shaft length and safety guard coverage protect both the tractor PTO bearing and the gearbox input from angular misalignment damage during field articulation.

Pasangan Gearbox Musiman

Jika traktor Anda juga menjalankan gearbox mesin pengepak jerami bundar for straw season or harvester equipment during grain harvest, Korea Ever-Power manufactures dedicated speed-increaser and rear-drive gearboxes rated from 30 to 100 KW. For ancillary machinery such as fertilizer spreaders or irrigation pumps, a self-locking worm gear reducer provides holding torque without a separate brake mechanism.
