PTO Shaft for Krone Round Balers | CV Joint Option

Product Overview

Krone round balers are among the most widely used European-made baling machines in the Korean hay and silage market. Models like the Comprima F 155 XC, Round Pack 1250, and Bellima F 130 are common sights during the autumn rice straw baling season across Chungcheong-do and Jeolla-do. When the PTO driveline on one of these machines wears out, replacing it through the Krone dealer network often means long lead times and premium European pricing. The PTO Shaft for Krone Round Balers from Korea Ever-Power provides an OEM-equivalent alternative that matches Krone's driveline specifications at 30 to 45 percent lower cost.

What sets Krone baler PTO shafts apart from other brands is the frequent use of CV joint (constant velocity) drivelines. Many Krone models specify a CV shaft rather than a standard double-cardan joint because the CV design runs smoother at the operating angles common in round baler hitching geometry. Our PTO Shaft for Krone Round Balers is available with or without the CV joint option, matching whichever configuration your specific Krone model requires.

 

Supported Krone Baler Models

The PTO Shaft for Krone Round Balers covers Comprima (F 125, F 155 XC, CV 150 XC), Round Pack (1250, 1550), and Bellima (F 125, F 130) series. Both standard cardan joint and CV joint configurations are available. The driveline category (CAT3 size 4 or CAT4 size 6) depends on the baler model and production year.

Why Krone Specifies CV Joint Drivelines

Most round baler manufacturers use standard double-cardan (universal joint) PTO shafts. Krone is one of the few that frequently specifies CV joint drivelines on their mid-range and premium models. The reason is operating geometry. Round balers sit relatively close to the tractor, and the PTO shaft operates at a moderate but constant angle. A standard U-joint at this angle generates speed pulsation, which in a baler creates uneven pickup feed and inconsistent bale density. The CV joint eliminates this pulsation, resulting in a smoother, more uniform baling operation.

Our PTO Shaft for Krone Round Balers with the CV joint option uses the same double-joint velocity-cancellation principle as the Krone OEM shaft. The housing dimensions, bearing size, and centering mechanism match the original so the shaft drops into the same mounting position without modification.

Clutch Types Used on Krone Baler Shafts

Krone round balers use three distinct clutch types depending on the model. The PTO Shaft for Krone Round Balers is available with each option to match your specific machine:

FT Friction Torque Clutch (FT32, FT34, FT42)

Spring-loaded friction plates that slip when torque exceeds the rated value (1000 Nm for FT32/FT34, 1450 Nm for FT42). Auto-resets when overload clears. The most common clutch type on Krone balers, protecting the baler's pickup gearbox from bale chamber overloads and foreign object impacts.

K64/2 Cutout Clutch

A cam-type overload clutch that disengages completely when torque exceeds the threshold (1050 or 1500 Nm depending on model). Unlike friction clutches that slip continuously, the K64/2 cuts out entirely and must be manually re-engaged by the operator. This is typically specified on Comprima models where a full stop is preferred over continuous slipping during a severe overload event.

FF1 Free-Wheel Clutch

An overrunning clutch that allows the baler to freewheel when the tractor decelerates. Prevents the baler's rotating mass from back-driving torque into the tractor PTO gearbox. Used on select Krone models where the chamber rotor mass is significant.

Safe Operation Practices for Baler PTO Shafts

Round baler PTO shafts operate at high torque and high RPM in dusty field conditions. The PTO Shaft for Krone Round Balers ships with a complete safety shield set, but the shield is only effective if these practices are followed:

• ⚠ Never open the baler chamber or approach the pickup area while the PTO is engaged
• ⚠ Ensure both shield halves are in place and rotating freely before each baling session
• ⚠ Attach all safety chains between shields and frames; a loose shield can jam and crack
• ⚠ If the clutch activates frequently during normal baling, investigate the cause before continuing (possible bale chamber buildup or gearbox issue)
• ⚠ Disconnect the PTO shaft from the tractor before performing any baler maintenance

Companion Products

Baler Gearbox Pairing

The PTO Shaft for Krone Round Balers connects to the baler's main agricultural gearbox, which drives the pickup, chamber, and wrapping mechanisms. If the old shaft failed from a severe overload, inspect the gearbox input bearing and seals before installing the new shaft. A damaged shaft can push metal debris into the gearbox housing, causing secondary damage.

Individual Components

CV joint housings, friction clutch plate sets (FT32, FT34, FT42), K64/2 cutout clutch assemblies, cross-bearing kits, yokes, and safety shields are available as separate replacement parts. If only the clutch or cross-bearings are worn, replacing just those components saves cost.

Frequently Asked Questions

Does the PTO Shaft for Krone Round Balers with CV joint match the OEM CV housing dimensions?

Yes. Our CV joint housing uses the same outer diameter, bearing spacing, and centering mechanism geometry as the Krone OEM unit. It drops into the same mounting position on the baler without modification.

How do I know if my Krone baler needs a CAT3 or CAT4 shaft?

Smaller Krone models (Bellima, entry-level Round Pack) typically use CAT3. Larger Comprima and premium Round Pack models use CAT4. Check your baler's operator manual or send us the model number for confirmation.

What's the difference between FT32 and FT42 friction clutches?

Torque rating. FT32 releases at 1000 Nm (for CAT3/size 4 shafts). FT42 releases at 1450 Nm (for CAT4/size 6 shafts). The friction plate diameter and housing dimensions differ accordingly.

Can I upgrade from a standard joint to a CV joint on my Krone baler?

In most cases yes, if the baler's PTO input shaft dimensions accommodate the CV housing. Contact us with your baler model and we'll confirm if the PTO Shaft for Krone Round Balers with CV option fits your specific machine.

Do you stock the K64/2 cutout clutch separately as a replacement part?

Yes. The K64/2 is available as an individual component for operators who need to replace just the clutch on their existing shaft. Both the 1050 Nm and 1500 Nm versions are stocked.

How often should I grease the CV joint on the PTO Shaft for Krone Round Balers?

Every 8 operating hours during active baling. CV joints run hotter than standard U-joints because of the internal bearing arrangement, so fresh grease is critical for heat dissipation and contamination flushing. Use NLGI #2 EP grease.

Customer Reviews

Hwang Byung-soo, Krone Comprima Owner, Chungcheongnam-do (autumn 2024)

"Comprima F 155 XC with the CV joint PTO shaft. The Krone dealer quoted me a three-week wait and a price that made me wince. Ever-Power had the exact CAT4 CV configuration with FT42 clutch in Korea. Arrived in five days, installed in twenty minutes, baled 4,000 rolls that season with zero issues."

---

Ryu Seung-min, Hay Contractor, Gangwon-do (spring 2025)

"We run two Krone Round Pack 1250 balers. Both now have Ever-Power CV shafts. The constant velocity joint makes a noticeable difference in bale uniformity compared to the standard U-joint shaft we tried first. The CV option is worth the small extra cost on Krone machines."

---

Jeong Soo-hyun, Agricultural Cooperative, Jeollanam-do (late 2024)

"Four Krone Bellima balers in our co-op fleet. Switched to Ever-Power CAT3 shafts with FT34 clutches across all four machines. Consistent quality, each shaft feels identical to the others. Annual driveline cost dropped by about 40%."

---

Kim Dong-hyun, Krone Equipment Dealer, Daejeon (mid 2024)

"I stock Ever-Power Krone-compatible shafts alongside genuine parts. Customers who've tried both tell me they can't tell the difference in field performance. The price difference is significant enough that most choose Ever-Power for replacement shafts while keeping the original Krone unit as a spare."

---

Oh Tae-kyung, Silage Producer, Gyeonggi-do (early 2025)

"Wrapping wet grass silage bales puts heavy loads on the baler driveline. The K64/2 cutout clutch on my Comprima shaft has tripped three times this season on overfilled chambers, each time preventing damage to the baler gearbox. The cutout clutch is a different feel from friction types but I prefer the complete disconnect for severe overloads."
