Descrizione
Reliable Power Transfer for Modern Farming Equipment
The HC-X30 agricultural gearbox is a purpose-built right-angle bevel transmission unit designed to handle the mechanical demands of today’s professional farming operations across the United Kingdom. Whether you are operating grain headers, forage harvesters, mower conditioners, or specialist root crop machinery, the HC-X30 delivers consistent torque transfer and long service intervals even under continuous field load. With three available gear ratio variants — 1:1.47, 1:1.69, and 1:1.93 — it accommodates a broad range of drive configurations without requiring external adaptors or custom fabrication. The unit accepts a standard 1 3/8 inch Z6 splined input shaft with an optic axis and cone base aequilate spline shaft output, making integration straightforward for both OEM manufacturers and field service engineers. At a gross weight of 26.5 kg, it balances structural robustness with practical handling on the workshop floor or in the field.
Ever-Power has supplied agricultural gearboxes to distributors and machinery builders across England, Scotland, Wales, and Northern Ireland for well over a decade, building a reputation for component consistency and responsive technical support. Every HC-X30 unit leaves our facility after a full power and noise test, verified against rated input speed and load conditions. This attention to process quality is why UK farm machinery dealers and OEM assembly lines continue to specify Ever-Power drivetrain components as their preferred agricultural gearbox supplier.

Why UK Farm Machinery Operators Specify the HC-X30
Precision Bevel Gear Cutting
CNC-hobbed bevel gears with tight tolerance grinding ensure quiet mesh engagement and minimal vibration even at sustained 540 rpm input speeds typical of UK tractor PTO systems.
Three Ratio Options, One Platform
The HC-X30 series covers 1:1.47, 1:1.69, and 1:1.93 gear ratios from a single housing envelope, giving OEM designers flexibility without redesigning mounting brackets or housings across product variants.
Sealed Bearing Arrangement
Double-lip seals on all shaft exits and a robust cast iron housing prevent ingress of field debris and moisture, a critical requirement for UK harvest conditions where mud, crop residue, and rain are constant factors throughout the operating season.
Direct-Fit Standard Shafting
The 1 3/8 inch Z6 splined input and cone base aequilate spline shaft output align with the universal tractor PTO standards used across virtually all major farm tractor brands sold in the United Kingdom, eliminating the need for intermediary adaptor shafts.
Compact Weight-to-Power Ratio
At 26.5 kg gross weight and rated at up to 35 HP, the HC-X30 agricultural gearbox provides one of the strongest weight-to-power ratios in its class, reducing unsprung machine weight without compromising structural integrity under peak field load cycles.
How the HC-X30 Agricultural Gearbox Works
Power enters the HC-X30 through the 1 3/8 inch Z6 splined input shaft connected directly to the tractor PTO at 540 rpm. The drive is transferred through a matched pair of precision-cut spiral bevel gears that redirect torque at 90 degrees while simultaneously adjusting the speed ratio according to the selected model variant. The output is delivered via the cone base aequilate spline shaft, which feeds the working implement — whether a mower rotor, baler flywheel, or elevator drive — with the correct torque-to-speed balance for that application. The spiral bevel tooth geometry distributes contact load across a wider face than straight-cut bevel designs, which substantially reduces peak tooth stress and operating noise. Oil splash lubrication covers all gear and bearing surfaces during operation, and the gearbox housing incorporates an integrated breather valve to equalise internal pressure during thermal cycling in the field.
The housing is manufactured from high-grade grey cast iron (EN-GJL-250 equivalent), chosen for its excellent vibration damping properties and machinability. Gear blanks are produced from 20CrMnTi alloy steel, carburised and case-hardened to HRC 58–62 before precision grinding, which gives each tooth a hard outer wear layer over a tough ductile core. Shafts are produced from 40Cr steel, induction-hardened at the bearing journals. All mating surfaces are ground to Ra 0.8 um or better to ensure consistent oil film retention and minimal running-in wear during early field hours.
| Componente | Materiale | Treatment | Beneficio |
|---|---|---|---|
| Alloggi | Grey Cast Iron EN-GJL-250 | Stress-relieved annealing | Vibration damping, dimensional stability |
| Bevel Gears | Acciaio legato 20CrMnTi | Carburised, HRC 58–62 ground | Long wear life under shock loads |
| Input/Output Shafts | 40Cr Steel | Induction hardened, ground journals | High fatigue resistance, minimal deflection |
| Cuscinetti | C3 Clearance Tapered Roller | Factory pre-loaded | Handles combined radial/axial forces |
| Seals | NBR Double-Lip | Spring-loaded lip | Excludes crop debris and moisture ingress |
Application Scenarios in Agricultural Machinery
The HC-X30 agricultural gearbox operates across a wide range of crop production and harvesting machinery. Its right-angle drive configuration suits any implement where the PTO axis needs to be redirected before reaching the working rotor or cutting head.

Customer Success Cases
Yorkshire Disc Mower Manufacturer, England
Agricultural Equipment OEM — 2024
A mid-sized Yorkshire-based implement manufacturer producing disc mower conditioners for the UK and Irish dairy grassland markets was experiencing premature gearbox failures on their 2.4 m working-width units during peak silage season. After switching to the HC-X30 HC-01-609 (1:1.47 ratio) across their full production run of 180 units, field failure incidents dropped from 12 per season to zero over the following two cutting seasons. The manufacturer also reported that the HC-X30 housing dimensional consistency reduced their assembly line fitment time by approximately 15 minutes per unit.
We have fitted the HC-X30 into our baler range for three seasons running. The agricultural gearbox handles peak bale chamber shock loads without any bearing noise or oil leaks, which was a recurring problem with our previous supplier. Delivery lead times from Ever-Power are consistently within the quoted window.
— M. Hargreaves, Production Engineer
Agricultural Machinery Manufacturer, Lincolnshire, England
I sourced the HC-01-611 variant for a custom root crop elevator project. The 1:1.93 ratio was exactly what our drive calculation required, and the cone base spline output meant zero modifications to our existing shaft assembly. Price per unit was very competitive compared to European-sourced alternatives, and the technical data sheet provided was thorough.
— D. McAllister, Design Engineer
Farm Equipment R&D Consultancy, Scotland
As a parts distributor covering Southern England, we stocked the HC-X30 range as a replacement unit for common disc mower gearbox failures on several European machine brands. The cross-compatibility with standard PTO shaft sizes means we can serve a broad customer base from a single SKU. Warranty claim rate on these agricultural gearboxes has been extremely low.

Manufacturing Facility & Custom Engineering Capability
Ever-Power’s dedicated agricultural gearbox workshop in Hangzhou operates CNC gear hobbing lines, automated case hardening furnaces, and coordinate measuring machines (CMM) for 100% outgoing inspection. Our production capacity exceeds 5,000 agricultural gearbox units per month across all series, giving UK importers and OEM customers reliable supply continuity even during peak pre-harvest ordering periods.
Beyond the standard HC-X30 catalogue configurations, our engineering team offers full custom gearbox design services — including modified housing geometry, alternative shaft arrangements, non-standard ratio selections, extended output shafts, flange-mount variants, and OEM white-label packaging. UK machine builders who require a specific ratio outside the 1:1.47–1:1.93 standard range, or a housing that mounts differently from the standard bolt pattern, are invited to share their technical drawings or requirements for a no-obligation feasibility review. We typically turn around engineering cost estimates within five working days of receiving complete specifications.
