PTO Shaft for New Holland BigBaler 330 & 340 | CAT5 Replacement
CAT5 PTO shaft engineered for New Holland BigBaler 330 & 340 square balers. Available in 540/1000 RPM with multiple spline options. CE certified, ships from Richmond, BC.
This CAT5-rated PTO shaft is engineered as a direct-fit replacement for New Holland BigBaler 330 and 340 large square balers. It delivers reliable torque transfer from the tractor's power take-off to the baler's 48-stroke-per-minute plunger system, supporting both 540 RPM and 1,000 RPM PTO driveline configurations. Available in three spline combinations — 1.375" × 6-spline, 1.375" × 21-spline, and 1.375" × 20-spline — this assembly matches the most common tractor PTO stubs used with BigBaler-series implements in North America, Europe, and Australia. The unit ships complete with CE-compliant safety guards, heat-treated universal joints, and telescoping profile tubes rated for continuous heavy-duty baling operations.
High-Performance Agricultural PTO Shaft Solutions
The New Holland BigBaler 330 requires a minimum of 102 PTO horsepower, while the BigBaler 340 demands at least 122 PTO HP to operate its high-speed plunger at full capacity. A PTO shaft that cannot sustain these power levels under continuous load will fail at the U-joint cross bearings or twist at the telescoping tube overlap — both are common causes of mid-season downtime on large square baler operations.
Our CAT5 PTO driveline assemblies are built to handle the specific demands of high-output square baling:
- Cross & bearing kit: 30.2 × 80 mm (Series 5), heat-treated 20CrMnTi carburized steel, rated for continuous operation above 120 HP at 1,000 RPM.
- Telescoping tubes: Lemon-profile inner and outer tubes, Q345 structural steel, minimum 150 mm (6") overlap at full extension to prevent separation during turns.
- Safety guard: CE-compliant free-spinning plastic shield with guard bearing kit, meeting DIN EN 12965 operator protection requirements.
- Overload protection: Shear-bolt clutch standard; friction-disc slip clutch available on request for operations exceeding 100 bales/hour.
- Operating angle: Standard universal joints rated to 25°; wide-angle (W/A) and constant-velocity (CV) configurations available for tight tractor-baler geometry.
Each PTO shaft for New Holland BigBaler 330 and 340 is individually inspected for spline concentricity, tube fit tolerance, and U-joint bearing preload before shipping. This process reduces installation rework and ensures smooth, vibration-free power delivery from the first engagement.
Technical Specifications of New Holland BigBaler Drive Shafts
Three PTO shaft assembly configurations are available for New Holland BigBaler 330 and 340 models. The correct part number depends on your tractor's PTO speed (540 or 1,000 RPM) and spline count:
PTO Shaft Assembly Configurations
| PTO Category / RPM | Tractor Spline | Part Number | Typical Application |
|---|---|---|---|
| CAT5 / 540 RPM | 1.375" × 6-spline | CS8R121U2WR7000 | Standard 540 RPM tractors |
| CAT5 / 1000 RPM | 1.375" × 21-spline | CS8R121U2WR8000 | Most common — high-HP tractors |
| CAT5 / 1000 RPM | 1.375" × 20-spline | CH8R121U2WR0000 | Certain European-spec tractors |
PTO Shaft Yoke Specifications
| Part Number | Diameter (in.) | Spline Count | Bore (mm) | C-E Length (mm) | Type |
|---|---|---|---|---|---|
| 5090L0360 | 1.375 | 6 | 68 | 133 | Splined |
| 5090L3760 | 1.375 | 21 | 68 | 133 | Splined |
| 5090L0460 | 1.750 | 6 | 68 | 133 | Splined |
| 5090L3860 | 1.750 | 20 | 68 | 133 | Splined |
Sizing note: Most BigBaler 330/340 operators in North America use a 1.375" × 21-spline tractor-side connection with a 1.750" × 6-spline implement-side input. Verify your tractor's PTO stub diameter and spline count before ordering. Contact our team if you need help identifying your configuration.

Why Choose Our Agricultural PTO Drive Shafts?
Tested at 120+ HP Continuous
Each CAT5 assembly is load-tested at torque levels exceeding the BigBaler 340's minimum 122 PTO HP requirement, ensuring no premature U-joint or tube failures during peak baling season.
20CrMnTi Carburized U-Joints
Cross bearings are forged from 20CrMnTi alloy steel and case-carburized to HRC 58-62 surface hardness. This delivers measurably longer service life compared to standard carbon-steel joints in abrasive field conditions.
CE + ISO 9001 / TS 16949
Every shaft ships with CE-compliant guards. Manufacturing follows ISO 9001 and TS 16949 quality management standards with full traceability from raw material to finished assembly.
24-Hour Quote, Same-Week Dispatch
We stock CAT5 assemblies in standard spline configurations in Richmond, BC. Custom-length or non-standard yoke orders are built and shipped within 5 business days across North America.
Frequently Asked Questions About PTO Shafts
Q: What PTO shaft series fits the New Holland BigBaler 330 and 340?
A: Both models require a CAT5-rated PTO shaft. The BigBaler 330 needs at least 102 PTO HP and typically runs at 540 or 1,000 RPM. The BigBaler 340 requires a minimum of 122 PTO HP at 1,000 RPM. The most widely used configuration is a 1.375" × 21-spline tractor end paired with a 1.750" × 6-spline implement input.
Q: How do I measure the replacement PTO shaft length for my BigBaler?
A: With the baler in its closest working position, measure from the tractor PTO stub end to the baler input shaft — that is your compressed length. Extend the implement to maximum travel and measure again. The replacement shaft must cover both distances while maintaining at least 150 mm (6 inches) of inner/outer tube overlap.
Q: Can I use a CV joint PTO shaft instead of a standard U-joint on my square baler?
A: Yes. Constant-velocity (CV) PTO shafts eliminate the cyclic speed variations that standard U-joints produce at operating angles above 8°. For BigBaler 330/340 setups where the tractor-to-baler angle exceeds 15° during turns, a CV joint assembly reduces vibration and extends driveline component life. Contact us to specify a CV-equipped shaft.
Recommended Companion Products
A new PTO shaft performs best when the components it connects to are also in good condition. Pair your shaft order with these related products to eliminate weak links in the driveline and avoid repeat teardowns during baling season.
Cross & Bearing Kits
Series 5 cross & bearing kits (30.2 × 80 mm) in sealed maintenance-free or greaseable configurations. 20CrMnTi carburized steel, HRC 58-62 surface hardness. Keep a spare set on hand during peak baling season so a worn U-joint never costs you a full working day.
