Who We Are
We Build the Gearboxes That Keep Australia Mowing
We are Ever-power Australia Mower Gearbox — a specialist manufacturer of right-angle bevel gearboxes, disc mower hub drives, and rotary tiller transmissions for the global agricultural industry. For over 20 years, we have dedicated our entire operation to one purpose: engineering gearboxes that farmers and contractors can depend on, season after season, in the toughest conditions on earth.
We started as a small gear-cutting workshop with a single Gleason machine and a handful of skilled machinists. Today, we operate a vertically integrated, ISO 9001:2015 certified production facility spanning over 15,000 square metres — housing 28 CNC machining centres, 12 dedicated gear production lines, automated heat treatment furnaces, a precision grinding department, and a climate-controlled metrology laboratory equipped with Zeiss coordinate measuring machines and Gleason gear analyzers.
Every gearbox that leaves our factory has been forged, machined, heat-treated, assembled, and tested under one roof — because we believe that controlling every step of the manufacturing process is the only way to guarantee the quality our customers expect.

Our Mission
Quality Gearboxes, Fair Prices — No Compromise
We founded this company on a simple conviction: no farmer anywhere in the world should have to choose between a gearbox that works and one they can afford. We saw an industry where replacement gearboxes were either overpriced genuine parts from OEM dealers or underbuilt imitations that failed within a single season. We set out to provide a third option — one that matches or exceeds OEM quality at 30-50% less cost.
That mission drives every decision we make — from the grade of alloy steel we source for our gear blanks (20CrMnTi forged, never cast) to the type of seals we specify (double-lip FKM, not single-lip NBR) to the way we test every finished unit (100% dimensional inspection, hydrostatic leak test, and no-load run-in). We invest in the details that determine whether a gearbox lasts 500 hours or 5,000 hours, because our reputation depends on the latter.
The result: a field failure rate below 0.3%, a repeat order rate above 85%, and a growing network of loyal customers across six continents who trust us with their equipment and their livelihood.
Our Manufacturing
What Happens Inside Our Factory
We control every step of production in-house — from raw steel to boxed gearbox. This vertical integration is how we guarantee consistent quality across 50,000+ units per year.
Forging & Material Preparation
We start with 20CrMnTi alloy steel billets, verified by spectroscopic analysis. Gear blanks are closed-die forged to align grain flow with tooth roots — increasing bending fatigue strength by 30% over cast alternatives. Every heat of steel arrives with an EN 10204 Type 3.1 mill certificate.
CNC Gear Cutting
Our 12 Gleason CNC gear generators cut spiral bevel tooth profiles to AGMA Class 8-10 accuracy. Each gear pair is generated as a matched set with optimised tooth contact patterns — verified on Gleason gear analyzers before moving to heat treatment.
Heat Treatment
Gas carburising furnaces achieve 1.0-1.5 mm case depth with HRC 58-62 surface hardness while maintaining a tough, ductile core. We monitor every cycle per CQI-9 standards and verify results with Vickers micro-hardness mapping on each production batch.
Precision Machining & Grinding
Housings are 5-axis CNC machined to ISO IT6 bore tolerance. All bearing seats are finish-bored to ensure interference fit. Post-hardening gear grinding achieves Ra 0.5 micrometre surface finish, reducing running-in wear and extending the interval to first service.
Assembly & Sealing
Trained technicians hand-assemble each gearbox in a temperature-controlled environment. Bearings are installed via induction heating for precise interference fit. Multi-lip FKM/NBR seals are seated using purpose-built fixtures, and each unit is filled with EP90 gear oil to the correct level.
Testing & Quality Gate
Every gearbox undergoes 100% CMM dimensional inspection, hydrostatic housing leak test at 1.5x rated pressure, and a 15-minute no-load run-in to verify smooth rotation, seal integrity, and correct oil level. Only after passing all gates does a unit receive its laser-etched serial number and packing release.
Our Advantage
Why Australian Farmers Trust Our Gearboxes
🇬🇧 We Understand Australian Conditions
We do not build generic gearboxes and hope they survive. We engineer specifically for the conditions our Australian customers describe — 45 degree C outback heat, red dust infiltration, rocky paddock impacts, waterlogged coastal pastures, and the sheer distances that make a mid-season breakdown a costly disaster. Our seal grades, oil capacities, and housing wall thicknesses reflect these realities.
⚙ We Control Every Manufacturing Step
Unlike brands that outsource gear cutting, heat treatment, or housing casting to third parties, we perform every operation in-house. This means we can trace any component back to its raw material lot, its machining operator, its heat treatment cycle number, and its inspection record. When quality is your responsibility end-to-end, there is nowhere to hide — and that is exactly how we want it.
💰 We Offer Genuine Value, Not Just Low Prices
Our gearboxes cost 30-50% less than OEM originals — not because we cut corners, but because we sell factory-direct without distributor markups. Independent metallurgical testing confirms our gear steel, case hardness, and bearing specifications meet or exceed OEM equivalents. We compete on value, never on a race to the bottom.
🚚 We Ship Fast and We Stock Deep
We maintain rolling inventory of our 35+ standard models for 3-5 day dispatch. We ship to every Australian state and territory via sea freight, air freight, and express courier. When a contractor calls on Tuesday with a gearbox failure and a client deadline on Friday, we make it happen — because we have been on the other end of that call often enough to know what is at stake.
🔧 We Support You After the Sale
Every gearbox ships with a 12-month warranty. We stock complete spare parts — gears, bearings, seals, shafts — for every model, dispatching within 24 hours. Our technical team provides installation guidance, troubleshooting support, and maintenance advice by phone, email, and video call. We are not done when we ship the box; we are done when your mower is running.
⚖ We Engineer Custom Solutions
Our 35+ catalog models cover 90% of replacement needs. For the other 10%, our R&D team designs custom gear ratios, shaft profiles, mounting interfaces, and housing modifications. We develop 15-20 new gearbox models every year, collaborating directly with OEM implement manufacturers across Australia, North America, and Europe.
