This PTO shaft<\/strong> is a CAT 7\/8 SFT SH Series constant-velocity assembly built for the Krone BIGpack<\/strong> range of large square balers. It transfers rotational power from the tractor PTO output to the baler gearbox and flywheel at 1,000 RPM, rated for continuous operation above 200 horsepower. The CV joint eliminates the cyclic speed pulses that standard U-joints produce at working angles, protecting the baler plunger, knotters, and drive chains from the vibration-induced fatigue that causes mid-season failures. Compatible models include the BIGpack 890, 1270, 1290, 1290 HDP, 1290 XC, 12130 HDP, and 12130 XC.<\/p>\n

High-Performance PTO Shaft Solutions for Krone BIGpack Series<\/h2>\n

Krone BIGpack balers operate at the upper limit of what a PTO driveline assembly must deliver. The 1290 HDP model alone requires 184\u2013245 PTO HP depending on generation, drives a 600 kg flywheel past 300 RPM, and cycles its plunger at 45 strokes per minute to produce bales weighing 800\u20131,100 kg. Every component in this PTO shaft is sized to handle those loads without degradation over a full baling season.<\/p>\n

Why CV over U-joints?<\/strong> At operating angles above 3\u00b0, standard universal joints create speed fluctuations of up to \u00b115% per revolution. On a 200+ HP driveline spinning at 1,000 RPM, those pulses translate into measurable shock loads on the baler gearbox. The constant-velocity joint on this PTO shaft maintains uniform rotational speed across the full angle range, eliminating that source of wear entirely.<\/p>\n<\/div>\n

<\/p>\n

Engineered for Extreme Baling Conditions<\/h2>\n

Large square baling subjects a PTO driveline assembly to a combination of forces that few other agricultural operations match: sustained high torque, continuous high RPM, cyclic shock from the plunger, abrasive dust ingestion, and constant telescoping motion during turns. This PTO shaft addresses each of those demands at the material and design level.<\/p>\n

\n
\n

20CrMnTi CV Joint Bearings<\/p>\n

Forged alloy steel, case-carburized to HRC 58\u201362. This grade resists pitting and spalling at the elevated bearing temperatures generated by 200+ HP continuous loads \u2014 a measurable improvement over standard carbon-steel joints in field endurance testing.<\/p>\n<\/div>\n

\n

Q345 Heavy-Wall Tubes<\/p>\n

Cold-drawn lemon-profile telescoping tubes with yield strength \u2265 345 MPa. The heavy-wall section prevents the torsional twist and buckling that thinner tubes develop under the 45-stroke-per-minute plunger cycle of Krone HDP balers.<\/p>\n<\/div>\n

\n

CNC-Machined Spline Bores<\/p>\n

Yoke splines are hobbed and ground to sub-0.05 mm concentricity. Tight spline tolerances eliminate the backlash that causes hammering at the tractor-shaft connection point \u2014 the second most common source of PTO driveline noise and premature wear.<\/p>\n<\/div>\n

\n

Zinc-Phosphate Corrosion Protection<\/p>\n

All exposed steel surfaces receive a zinc-phosphate conversion coating before assembly. The safety guard is finished in UV-stabilized polymer to prevent cracking during extended outdoor storage between seasons.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

Essential Replacement PTO Shaft Components<\/h2>\n

When ordering a replacement PTO shaft for Krone BIGpack 1290 or any other model in the range, it helps to understand the four main wear zones and the components that address them. Each zone has a different failure mode, a different inspection interval, and a different replacement trigger:<\/p>\n

This PTO shaft ships as a fully assembled unit covering all four zones. If you only need individual components \u2014 a cross & bearing kit, a replacement guard, or a single yoke \u2014 contact our team. We can supply parts separately for existing PTO drive shaft assemblies still within their serviceable lifespan.<\/p>\n

Questions About PTO Shaft for Krone BIGpack Square Balers<\/h2>\n

<\/p>\n

\n

Q: What PTO shaft category does the Krone BIGpack 1290 HDP require?<\/p>\n

A: The BIGpack 1290 HDP uses a CAT 7\/8 SFT SH Series constant-velocity PTO shaft at 1,000 RPM. This same assembly fits all seven BIGpack models from the 890 through the 12130 XC.<\/p>\n<\/div>\n

<\/p>\n

\n

Q: What is the advantage of a CV joint over standard U-joints on a BIGpack?<\/p>\n

A: U-joints produce speed variation up to \u00b115% per revolution at operating angles above 3\u00b0. On a 200+ HP baler driving a 600 kg flywheel, those pulses accelerate knotter, gearbox, and chain wear. The CV joint delivers uniform speed, removing that failure source.<\/p>\n<\/div>\n

<\/p>\n

\n

Q: How do I know when my PTO shaft needs replacing rather than servicing?<\/p>\n

A: Replace the full assembly if the CV joint shows pitting or heat discoloration, if the telescoping tubes have more than 3 mm of axial play, or if the yoke spline free-play exceeds 2\u00b0. Individual components (bearings, guards) can be replaced separately if the rest of the shaft is serviceable.<\/p>\n<\/div>\n

<\/p>\n

\n

Q: Does this PTO shaft fit the latest Krone BIGpack Gen 5 models?<\/p>\n

A: The CAT 7\/8 CV shaft is compatible with Gen 5 BIGpack 1290 variants (BP 405 series). Contact us with your baler serial number so we can verify the exact yoke profile and compressed length for your specific unit.<\/p>\n<\/div>\n

<\/p>\n

\n

Q: What is the greasing schedule for this CV PTO shaft?<\/p>\n

A: Apply NLGI Grade 2 lithium grease to CV joint points every 8 operating hours. Coat the telescoping tube profiles with moly grease before the season and again at the midpoint. Inspect the guard bearing and shear bolts at the same intervals.<\/p>\n<\/div>\n

<\/p>\n

Recommended Companion Products<\/h2>\n

Inspecting adjacent driveline components when fitting a new PTO shaft prevents the kind of cascading failures that cost full working days during peak baling season. Consider pairing your order with these items.<\/p>\n

\n
\n
<\/div>\n
