PTO Shaft for Krone BIGpack Square Balers 1290 / 1290HDP / 1290XC / 12130XC
Engineered to meet the exacting torque demands of Krone high-capacity square balers, this heavy-duty PTO shaft delivers consistent rotational power across the most challenging harvesting conditions. Trusted by UK agricultural contractors and farm operators from East Anglia to the Scottish Borders.
What Makes This PTO Shaft the Right Fit for Krone BIGpack Balers?
The Krone BIGpack range — covering the 1290, 1290HDP, 1290XC, and 12130XC — represents some of the most productive square baling machinery available to UK arable and forage farmers today. These machines operate at high throughput rates and place enormous cyclic loading demands on every drivetrain component, particularly the PTO shaft. A shaft that cannot handle the harmonic shock loads generated during high-density bale formation will fail prematurely, bringing harvest operations to a costly standstill. Our replacement PTO shaft is manufactured specifically to match Krone’s OEM geometry, yoke dimensions, and torque ratings — without the premium price tag of dealer-supplied parts.
Whether you are a large-scale arable contractor running multiple machines across Lincolnshire or a mixed farm operator in Yorkshire replacing a worn shaft mid-season, this component is engineered to drop straight in. The shaft is dimensionally interchangeable with the factory-fit unit, and full compatibility has been verified against Krone parts documentation for all four BIGpack variants listed above. Downtime is minimised, and your baler gets back to work.
Product Advantages
OEM-Matched Geometry
Yoke profiles, spline counts, and overall compressed/extended lengths match Krone factory specifications for the BIGpack 1290 series — no modifications or adaptors required on installation.
Integrated Safety Guard
A full-coverage plastic safety shield is included as standard, meeting CE marking requirements relevant to UK agricultural machinery directives and keeping operators protected during high-speed operation.
High-Capacity Torque Rating
Rated to handle the peak torque loads generated by Krone’s high-density baling chamber — including the extreme compression spikes produced by the 1290HDP model — without fatigue cracking at the weld zones.
Forged Alloy Steel Construction
Yokes and cross-journals are forged from high-strength alloy steel, heat-treated to achieve the hardness balance between toughness and wear resistance required for continuous field operation at 1000 RPM PTO speeds.
Telescoping Spline Profile
The inner profile is precision-machined with a lemon-profile or star-profile spline (matched to Krone spec) ensuring smooth telescoping under load while preventing rotational backlash that causes premature wear.
Competitive B2B Pricing
Direct factory supply means agricultural dealers, machinery importers, and large farm estates across England, Scotland, and Wales receive trade pricing well below main dealer retail rates — with volume discounts available.
Operating Principle, Materials & Application Environments
A PTO shaft transmits rotational power from a tractor’s power take-off output stub to the driven machine — in this case the Krone BIGpack’s flywheel and gearbox assembly. It does so through a combination of universal joints (Cardan joints) that accommodate angular misalignment between tractor and baler as the implement follows ground contours, and a telescoping inner tube that accommodates changes in working length during turning or over undulating terrain.
The yokes — the fork-shaped ends that connect to tractor stub and baler input — are drop-forged from 20CrMnTi or equivalent high-alloy steel, then case-hardened. The cross-journal spider bearings are lubricated via grease nipples accessible without removing the safety guard. The outer telescoping tube is drawn seamless steel tube, finished with a zinc-phosphate coating to resist the corrosive mix of field moisture and fertiliser spray common across UK arable farmland.
Operationally, this PTO shaft performs across all BIGpack application scenarios: cereal straw baling in East Anglian combine harvests, hay and silage baling in Midlands livestock regions, and large-scale forage contracting in Scotland and Northern Ireland. The component handles both standard 1000 RPM and, where specified, 540 RPM tractor PTO outputs, making it versatile across the broad range of tractor horsepower pairings used with the Krone BIGpack 1290 family.
Technical Specifications
This Constant Velocity PTO will operate efficiently at 200 Horse Power and beyond @ 1000 RPMs.

Customer Success: How UK Operators Are Using This PTO Shaft
Case Study: Lincolnshire Arable Contractor — Summer 2024 Cereal Harvest
A busy arable contracting business operating three Krone BIGpack 1290HDP units across Lincolnshire and Nottinghamshire experienced a PTO shaft failure at the input yoke weld during peak barley straw baling. With dealer lead times of 10–14 working days and harvest weather closing in, the operator contacted us directly. A replacement shaft was despatched from our UK logistics partner within 48 hours. The shaft fitted without modification, and the machine returned to the field the same afternoon it arrived. Over the remainder of the season, zero further drivetrain issues were reported across two of the three units now running our shafts.
🏭 Industry: Arable contracting | 🇧🇷 Location: Lincolnshire, UK | 📈 Outcome: Same-day return to operation
“Fitted our BIGpack 1290XC without any issues. The yoke dimensions were spot on and the safety guard quality was noticeably better than the last aftermarket shaft we tried. Will be ordering two more for the rest of the fleet.”
— James H., Farm Manager, Yorkshire Dales
“As an agricultural machinery dealer in East Anglia, I need reliable suppliers who can turn orders around quickly before harvest. These PTO shafts arrived well-packaged, technically accurate and at a price point that works for our trade customers. Solid product.”
— David L., Parts Manager, East Anglia Agricultural Dealers
“Running a Krone 12130XC for large-scale silage contracting in Scotland means the drivetrain takes a real hammering. The shaft has done two full silage seasons now with regular greasing and no failures. The price compared to the Krone dealer was considerably lower, and the quality holds up.”
— Alasdair M., Agricultural Contractor, Perthshire, Scotland

Which PTO shaft fits both the Krone BIGpack 1290XC and the 12130XC, and what are the key differences I need to check before ordering?
Both the 1290XC and 12130XC share the same PTO input configuration in most build years. The key items to confirm are the compressed and extended shaft length (which varies by tractor coupling position), yoke bore size, and whether a friction clutch or shear bolt limiter is required. Share your machine’s serial number or existing shaft measurements and our engineers will confirm the correct specification.
Where can I find a reliable aftermarket PTO shaft for my Krone BIGpack square baler operating in Scotland or Northern England?
We ship to all UK regions, including Scotland, Yorkshire, Cumbria, and Northern Ireland. Our logistics partner provides next-day delivery to most Scottish mainland postcodes. Enquiries from farm estates, contracting businesses, and machinery dealers in these regions are very welcome — email us or use the Get a Quote link on this page.
When should I replace the PTO shaft on my Krone BIGpack baler, and what signs of wear should arable contractors look out for during pre-harvest inspection?
Replace the shaft if you notice vibration at operating speed, visible play in the cross joint, grease leaking from bearing caps, cracks near yoke weld zones, or binding in the telescoping section. During pre-harvest checks, rotate the shaft by hand to feel for bearing roughness, and inspect the safety guard for cracks or missing sections. A shaft showing any of these signs should be replaced before the season starts rather than risking a mid-harvest failure.
What is the difference between a friction clutch and a shear bolt overload protection on a Krone BIGpack PTO shaft, and which one should I choose for high-density baling in UK conditions?
A friction clutch slips when torque exceeds the set limit, protecting the gearbox without requiring part replacement. A shear bolt limiter uses a sacrificial bolt that fractures under overload — cheaper upfront but requires you to carry spare bolts and stop the machine to reset. For high-density baling in variable crop conditions (common in UK mixed-arable operations), a friction clutch is generally preferred as it handles repeated torque spikes without stopping the machine. For lighter or more predictable loading, a shear bolt is a cost-effective choice.
