Agricultural & Industrial Power Transmission
PTO Drive Shaft G Series — Heavy-Duty Performance for UK Agriculture & Industry
The PTO Drive Shaft G Series is an engineered power take-off transmission solution built to handle the most demanding conditions across UK farms, construction sites, and industrial plants. Spanning nine sub-models from G2 through G50, the series covers a peak torque range of 450 Nm to 3,700 Nm, matching the precise power requirements of modern agricultural machinery and heavy commercial equipment. Whether your application runs at 540 RPM or 1,000 RPM, this pto drive shaft range delivers smooth, reliable torque transfer with minimal vibration — giving your operation the uptime it demands throughout the entire season.
What Makes the G Series a Go-To PTO Drive Shaft for UK Operators?
At its core, a PTO drive shaft transfers rotational power from a tractor or prime mover to an attached implement — a mower, slurry spreader, baler, or auger — using a series of universal joints, telescoping tubes, and a protective outer guard. The G Series takes this fundamental mechanism and raises every engineering standard. The tube sections are manufactured from high-strength cold-drawn seamless steel, allowing the shaft to absorb torque shock loads that would crack lesser components. Cross-and-bearing universal joints are precision-machined to tight tolerances and grease-lubricated through accessible nipples, so maintenance in the field takes minutes rather than hours.
The telescoping design accommodates variable operating lengths, which is critical on undulating UK terrain where the distance between tractor PTO stub and implement changes with every pass. The plastic outer guard — moulded from impact-resistant polyethylene — shields the rotating shaft from debris, mud, and straw, protecting both the component and the operator in full compliance with PSSR 2000 and the relevant provisions of PUWER 1998. Every G Series unit ships with yoke profiles matched to standard 1-3/8″ six-spline and 1-3/4″ six-spline interfaces, covering the vast majority of tractors operating in British agriculture today.
Why UK Buyers Choose the G Series PTO Drive Shaft
Wide Torque Range
From 450 Nm (G2) up to 3,700 Nm (G50), one product family covers light cultivation tasks all the way up to high-demand slurry and harvesting applications without switching suppliers.
Robust Cold-Drawn Steel Tubes
Seamless tube construction eliminates weld seams — the most common fatigue failure point on lesser shafts — ensuring consistent wall thickness and superior torsional strength under cyclic loading.
CE-Compliant Safety Guard
The full-cover polyethylene guard with free-rotating outer cone meets CE machinery directive requirements, reducing risk to personnel and satisfying UK Health & Safety Executive expectations for power transmission guarding.
Dual-Speed Compatibility
Rated at both 540 RPM and 1,000 RPM operation, the G Series matches the PTO speeds found on virtually all modern tractors in the UK market, from compact 40 hp units to 200+ hp flagship models.
Customisable Configurations
Non-standard yoke profiles, extended tubes, shear bolt overload protection, or torque limiting clutches can all be specified at order stage — no minimum quantities required for customised builds destined for OEM or replacement markets.
Fast UK Delivery
Stock items are dispatched within 48 hours to mainland UK addresses. Purpose-built and customised units typically ship within 10–15 working days, keeping your machinery downtime to an absolute minimum during peak harvest or cultivation periods.

Where the G Series PTO Drive Shaft Performs Across the UK
Across England, Scotland, Wales, and Northern Ireland, G Series shafts are working every day in conditions as varied as the landscapes they operate in. Arable farms in Lincolnshire running large-diameter rotary cultivators lean on G7 and G8 units for their sustained high-torque output at 540 RPM. Livestock farmers in Devon and Pembrokeshire running slurry tankers with hydraulic agitators specify G6 or G38 units for smooth engagement under variable load. Groundscare contractors maintaining golf courses across Surrey and Yorkshire prefer the lighter G2–G5 models on flail mowers and aerators, where low weight and quick attach-detach access matter more than peak torque.
Beyond agriculture, the G Series sees regular deployment in industrial settings. Quarry operators in Scotland use G42 and G50 shafts to power screening and crushing auxiliary drives. Waste management companies in the Midlands fit them to shredder input shafts where shock-load resistance is essential. Food processing plants requiring hygiene-compliant shaft assemblies can specify stainless yoke options. The unifying thread across all these scenarios is the same: a PTO drive shaft that shows up, transmits power accurately, and doesn’t ask for attention until the next scheduled service interval.

How UK Operators Are Getting Results with the G Series
Real applications. Real feedback. Verified procurement outcomes.
Fenland Arable Co-operative, Cambridgeshire, UK
Application: G7 & G8 units on 6m power harrows, spring 2024 season
A co-operative managing approximately 4,800 hectares of arable land in Cambridgeshire had been experiencing persistent shaft failures on their fleet of six-metre power harrows midway through the spring drilling window — a catastrophic problem when every hour of good soil conditions is worth money. After switching their three highest-use tractors to G8 PTO drive shafts and fitting shear bolt overload clutch assemblies, they completed the entire 2024 spring campaign without a single shaft-related stoppage. The maintenance team noted that grease nipple access on the new shafts was noticeably better than the outgoing units, reducing the greasing run from 40 minutes to under 20 minutes across the fleet.
“We’d had the same shaft supplier for eight years and never questioned it. One season with the G8 units and we can’t imagine going back. The build quality is a clear step up.”
— Operations Manager, Fenland Arable Co-operative
“Ordered G5 shafts for our flail mower fleet — 12 units, custom length, delivered in 12 working days. No fuss, no missing parts, everything fitted straight away. Price was very competitive against the UK distributors we’d been using.”
— James H., Groundscare Contractor, North Yorkshire
“We source G38 and G42 shafts for our industrial shredder lines in the Midlands. Two years in, zero warranty claims. The torque capacity is genuine — these shafts handle shock loads that would destroy cheaper alternatives. Highly recommend for heavy industrial use.”
— Procurement Manager, Waste Processing Facility, West Midlands
“Running G6 units on our slurry tankers across 15 farms in Pembrokeshire. Third season now. The guards are holding up better than any other brand we’ve tried and the grease points are genuinely accessible — that matters when you’re servicing in a cold yard in January.”
— Farm Machinery Specialist, Pembrokeshire Agricultural Contractor

Często zadawane pytania
What is the best PTO drive shaft for a 100 hp tractor running a slurry tanker in the UK?
▼
For a 100 hp tractor in UK slurry applications at 540 RPM, the G6 or G7 models are the most commonly specified. The G6 handles up to 1,450 Nm peak torque and the G7 up to 1,800 Nm — both comfortably within the envelope of most tanker agitator drives at that power level. If the tanker runs a high-inertia rear pump, fitting a shear bolt clutch on a G7 unit adds valuable overload protection during pump start-up.
How much does a G Series PTO drive shaft cost and where can I get a price for UK delivery?
▼
Pricing depends on the sub-model (G2 through G50), shaft length, yoke profile, and any clutch options. Standard in-stock configurations are typically the most cost-effective. For an accurate quote with UK delivery costs included, email [email protected] with your required series, compressed and extended lengths, and yoke specifications. You’ll receive a full landed price quotation within one business working day.
Which G Series model should I choose for a 6-metre power harrow on a 150 hp tractor in Lincolnshire?
▼
A 6m power harrow paired with a 150 hp tractor typically operates at or near the G8 specification — rated at 2,250 Nm peak torque. Given the shock-load nature of power harrow operation in heavy Lincolnshire soils, adding a torque-limiting clutch assembly to the G8 shaft is strongly recommended to protect both the gearbox and PTO stub.
Do you supply PTO drive shafts with CE-compliant guards meeting UK Health and Safety Executive requirements?
▼
Yes. All G Series PTO drive shafts are supplied as standard with full-cover polyethylene guard assemblies meeting the CE Machinery Directive. These incorporate a free-rotating outer cone and comply with PUWER 1998 guarding requirements — the current applicable UK regulation for work equipment guarding.
How long does delivery take when ordering G Series PTO drive shafts to a farm in Scotland or Wales?
▼
Standard in-stock models are dispatched within 48 hours and reach mainland Scottish and Welsh farm addresses in 3–5 working days via pallet courier. Highland and island locations may require an additional 2–3 days. Custom-length or non-standard configurations typically ship within 10–15 working days from order confirmation.
Can I order custom-length PTO drive shafts for an OEM agricultural machinery build in England?
▼
Absolutely. Custom shaft lengths, non-standard yoke bolt circles, specific spline profiles, and integrated clutch options are all available for OEM builds. There is no minimum order quantity for custom configurations — we can produce a single prototype and scale to production volumes as your programme demands. Contact our engineering team with your drawings or dimensional requirements.
What is the difference between a 540 RPM and 1,000 RPM PTO drive shaft and which speed is right for my UK application?
▼
540 RPM is the older standard found on most tractors up to around 100 hp and on implements such as mowers, spreaders, and balers. 1,000 RPM is used on higher-power tractors and faster implements such as forage harvesters and large rotary cultivators. The G Series is rated at both speeds. Always check your implement’s data plate for the required input speed and match accordingly — running a 540 RPM implement at 1,000 RPM will cause immediate damage.
