540 RPM Input
UK Farming Ready
Why UK Farmers Choose This Model
Designed for the demanding conditions of British agriculture — from the wet fields of Yorkshire to the mixed-terrain farms of Devon — this aluminum gearbox offers corrosion resistance, low running weight, and precise torque delivery without the maintenance burden of cast iron alternatives.

Product Overview
The HC-01-674 agricultural gearbox is part of Ever-Power’s Aluminum Box Series — a line engineered from the ground up for modern tractor-implement interfaces common across the United Kingdom. At its core, this gearbox is a precision-machined torque transmission unit built to handle the variable loads of British farmland, from spring cultivation to late-season baling. The aluminum housing dramatically reduces overall equipment weight compared to conventional cast-iron gearboxes, which is particularly valuable for rear-mounted implements where rear axle loading is a constant concern for UK operators working on sloped or soft terrain.
Rated at 23 HP with a 540 rpm input speed, this сільськогосподарська коробка передач delivers a 1.46:1 speed ratio through a 19/13 tooth gear pair with Module 5 specification — a configuration that balances torque multiplication with rotational smoothness. The 1 3/8 Z6 input/output shaft profile is fully compatible with standard UK tractor PTO configurations, making installation straightforward for farm machinery dealers and operators alike. Weighing just 7.2 kg, the HC-01-674 imposes minimal parasitic load on the host machine, preserving tractor fuel efficiency across long working days.

Engineering Drawing / Dimensional Reference
Materials, Working Principle & Application Scenarios
⚙ Housing Material
Die-cast aluminum alloy housing delivers an excellent strength-to-weight ratio. The alloy is treated with anti-oxidation surface coating for long-term performance in the humid field conditions typical of UK agricultural seasons, including exposure to fertilisers, silage effluent, and frequent washdowns.
⚡ Working Principle
Power enters through the 1 3/8 Z6 input shaft at 540 rpm from the tractor PTO. A helical or straight-cut gear pair (19 drive teeth / 13 driven teeth) meshes inside the sealed housing, stepping up speed at the 1.46:1 ratio. The output shaft then drives the implement directly. Sealed bearings and splash lubrication ensure quiet running under sustained field load.
🌿 Application Scenarios
This сільськогосподарська коробка передач finds application in rotary mowers, spreaders, tedders, rakes, small square balers, irrigation pump drives, and strip-till cultivators. It is particularly suited to British mixed farms running tractors in the 30–60 HP class, where compact, lightweight driveline components are essential for headland manoeuvring.
Why the HC-01-674 Stands Apart
☉
Lightweight Build
At just 7.2 kg, the HC-01-674 reduces implement deadweight, lowering soil compaction risk on sensitive British pasture and arable ground — a genuine agronomic benefit, not just an engineering one.
🔳
Standard PTO Compatibility
The 1 3/8 Z6 shaft profile is the universal standard across UK tractor brands — John Deere, Massey Ferguson, New Holland, Case IH — ensuring drop-in fitment without costly adapters or modifications.
🔨
Low Maintenance Design
Sealed gear housing with precision-engineered oil seals means this agricultural gearbox operates for full seasonal runs without routine internal servicing — important for operators who cannot afford machinery downtime during peak harvest windows.
📈
Precise Torque Ratio
A 1.46:1 ratio is ideal for applications requiring moderate speed multiplication without excessive torque reduction — matching rotary mower blade tip speed targets and spreader disc rotation requirements common to UK grassland farming.
Related Aluminum Box Series Agricultural Gearboxes
If your application requires a different torque ratio, power rating, or shaft configuration, our Aluminum Box Series includes a full range of matched сільськогосподарська коробка передач models engineered with the same quality standard as the HC-01-674. The following models are frequently selected alongside the HC-01-674 for multi-function implement lines:
HC-RV022 (X) Aluminum Box Series
An extended-range aluminum gearbox with reinforced gear mesh for higher-demand implements. Often specified for heavy grassland and wide-cut mowing applications across the UK.
HC-RV010 Aluminum Box Series
A compact input-drive variant in the same aluminum housing family. Popular with UK distributors supplying lightweight tractor implements for horticultural and small-acreage farming operations.

Greenfield Farm Machinery Ltd — North Yorkshire, England
Agricultural Implement Manufacturer • Est. 2009
Greenfield Farm Machinery supplies compact rotary tedders and side-discharge rakes to mixed livestock farms across Yorkshire and the North Pennines. In 2024, their engineering team sourced 200 units of the HC-01-674 сільськогосподарська коробка передач to replace heavier cast-iron units that were contributing to rear hitch overloading on smaller 45 HP tractors. The weight saving of approximately 4 kg per unit allowed them to redesign the implement frame, bringing the total implement weight within the manufacturer’s hitch rating for 40-plus HP tractors — opening a substantially wider customer base. Field trials across the 2024 summer season confirmed zero gearbox failures, consistent PTO engagement, and no oil seal issues across 800+ operating hours in total across 12 machines.
What Our UK Customers Say
«
We’ve been fitting Ever-Power agricultural gearboxes on our tedder line for two seasons. The 7.2 kg weight is a real bonus — our 45 HP customers can finally run the implement without worrying about overloading the linkage. Build quality is exactly what we needed at this price point.
— James W., Production Manager
Greenfield Farm Machinery, Yorkshire
«
Sourced 60 units for our spreader rebuild programme. The 1 3/8 Z6 shaft fits straight onto our John Deere linkage without adapters. Lead times were well-managed and the export documentation was clean. Will be ordering the HC-RV022 range next season for our larger implements.

«
I run a small implement repair business in Devon and regularly recommend Ever-Power replacement gearboxes to my farmers. The HC-01-674 is a well-priced, drop-in replacement for older mower gearboxes. I’ve had zero comeback on the units I’ve supplied — and that means everything in this trade.
