A strong tractor PTO shaft needs the right end connections and working length for the tractor and implement, with a series and capacity suited to the job. The Mkekexe T1-680 is a strong starting point for buyers seeking a 1-3/8-inch, six-spline connection at both ends and a 27-to-35-inch size range. This roundup covers compact T1 shafts, adjustable mid-length models, longer Series 4 drivelines, and options sold with a slip clutch.
Those differences matter: a shaft that fits one tractor-and-implement pairing may not fit another, even when the spline size looks familiar. Check the compressed and extended dimensions, end styles, and listed capacity against your equipment before choosing.
The products below are ranked by how clearly their listed details serve common tractor PTO replacement needs.
The Mkekexe T1-680 is the leading choice for a common 1-3/8-inch, six-spline tractor-and-implement pairing. Its listed 27-to-35-inch range suits mid-length installations, and the product description specifies a T1 driveline with a 20CrMnTi carburized steel universal joint and Q345 steel tube. That combination of standard ends, useful adjustment range, and stated construction makes it the most versatile starting point here.
Confirm the actual working length and implement connection before ordering; the listed size alone cannot establish fit for every setup.

Its T1 series designation and stated 1-3/8-inch, six-spline tractor end identify key replacement details; confirm the implement-side connection from the actual equipment requirements. The 20CrMnTi carburized-steel universal joint and thick Q345 triangular tube inside the safety shield are described for wear and torsion resistance under heavy loads and muddy conditions.
- 20-to-24-inch shaft range
- T1 series driveline
- 20CrMnTi carburized-steel universal joint
- Thick Q345 triangular steel tube inside the safety shield
- The 24-inch maximum length restricts it to very short connections.
Skip it if you need a shaft longer than 24 inches; the Mkekexe T1 27-35-inch model covers a longer span.
This Mkekexe is for a buyer replacing a short-span T1 driveline on compatible farm equipment. Its 20-to-24-inch range is the decisive boundary; it is not the choice for connections needing more length.

4. CHEDA Series 4 Slip-Clutch Shaft
- Dimensions: 33.89 x 7.88 x 7.88 in
- Weight: 34 lb
Best for: Slip-clutch Series 4 setup.
Why it ranks #4: The 31.5-to-41-inch Series 4 shaft includes a slip clutch and six-spline 1-3/8-inch ends; listed capacity reaches 35 Hp at 540 rpm.
A listed slip clutch distinguishes this CHEDA Series 4 shaft for buyers seeking that feature in a 31.5-to-41-inch driveline. Its 1-3/8-inch six-spline ends match the stated connection style at both tractor and implement, while published power and torque figures help assess the application.

6. ACZCR Long PTO Shaft
- Dimensions: 39.96 x 6.3 x 5.91 in
- Weight: 24.4 lb
Best for: Longer-range higher-capacity shaft.
Why it ranks #6: Its 39-to-62.5-inch span serves longer installations, and the listing states six-spline ends plus 460 Nm at 540 rpm.
Its 39-to-62.5-inch adjustment range pairs longer reach with listed ratings of 35 hp at 540 rpm and 55 hp at 1,000 rpm. The ACZCR shaft uses 1-3/8-inch six-spline ends on both sides, making it a fit candidate for matching tractor and implement connections.
The 39-inch compressed and 62.5-inch extended lengths serve connections that exceed the shorter shafts’ ranges, while the dual six-spline 1-3/8-inch ends specify the required fitting style. ACZCR lists 460 Nm at 540 rpm and 380 Nm at 1,000 rpm, alongside the horsepower figures, giving buyers operating data to compare with their application. At 24.4 pounds, its weight is also relevant when handling and positioning a longer shaft during installation.
- 39-inch compressed length
- 62.5-inch extended length
- Six-spline 1-3/8-inch ends on both sides
- 35 hp at 540 rpm and 55 hp at 1,000 rpm
- At 24.4 pounds, it is a heavier shaft to position during installation.

7. VEVOR Series 4 Shaft
- Dimensions: 75 x 6 x 5 in
- Weight: 28.2 lb
Best for: Long-reach mixed-end replacement.
Why it ranks #7: The 51-to-75-inch Series 4 shaft suits long setups, but its round implement end differs from the six-spline implement ends on many alternatives.
Its 51-to-75-inch working range reaches farther than the compact PTO options, while the 1-3/8-inch six-spline tractor end and round implement end suit equipment with that specific mixed-end arrangement. The Series 4 driveline’s steel construction gives buyers a substantial replacement option for a finish mower or rotary cutter.
The 51-inch minimum and 75-inch maximum give more length to work with when connecting a tractor and implement that need this extended span. Check the round implement end carefully against your implement connection: the tractor end is six-spline, but the implement end is round, unlike shafts with splines at both ends. A solid 20CrMnTi carburized-steel universal joint and Q345 steel tube inside the shield are specified for the driveline, supporting its agricultural-machinery use.
- 51-to-75-inch length range
- 1-3/8-inch six-spline tractor end
- Round 1-3/8-inch implement end
- 20CrMnTi joint and Q345 steel tube
- At 28.2 pounds, it is a substantial shaft to handle during installation.
Skip it if you need a six-spline implement connection; the YIHETOP T1 27-35-inch shaft has six-spline ends on both sides.
Choose this VEVOR for a longer-span connection to an implement with a round end and a tractor with a 1-3/8-inch, six-spline PTO. Its mixed-end configuration and 51-to-75-inch range are important fit boundaries.

8. YIHETOP T1 Shaft
- Weight: 12.71 lb
Best for: Compact dual-spline connection.
Why it ranks #8: Its 26.8-inch compressed and 35.4-inch extended lengths suit a mid-range setup, with standard 1-3/8-inch six-spline ends at both sides.
A 26.8-inch compressed length and 35.4-inch extended length make this YIHETOP a compact-range choice for a tractor-to-implement connection. Both ends use 1-3/8-inch, six-spline fittings, so buyers seeking a matching dual-spline arrangement can focus on the stated length and connection type.
The 680 mm compressed and 900 mm extended measurements describe a relatively short adjustment span, useful when the required connection falls within those dimensions rather than a longer shaft range. Six-spline ends on both the tractor and implement sides keep the connection type consistent, while the stated 1-3/8-inch size identifies the specified fitting size. Those details make length and end style the key checks before putting this shaft into a mower or other compatible machinery.
- 26.8-inch compressed length
- 35.4-inch extended overall length
- 1-3/8-inch standard size
- Six-spline ends at both sides
- Its 35.4-inch maximum length limits use to shorter-span connections.
Skip it if you need a span beyond 35.4 inches; the SCITOO Yellow shaft extends to 40.55 inches.
This YIHETOP suits buyers whose tractor and implement use 1-3/8-inch six-spline connections and need a compact shaft no longer than 35.4 inches. Its short adjustment range is the central fit boundary.

9. Generic Series 4 Shaft
- Dimensions: 39 x 6 x 6 in
- Weight: 19.7 lb
Best for: Compact mixed-end Series 4.
Why it ranks #9: The 30-to-39-inch shaft lists a six-spline tractor end and round implement end, limiting its fit to equipment with that matching implement connection.
A 30-to-39-inch range gives this Series 4 shaft a compact reach for a tractor with a 1-3/8-inch, six-spline PTO and an implement with a round end. Its forged driveline construction includes a 20CrMnTi universal joint and Q345 steel tube inside the shield.
The 30-to-39-inch range positions this shaft for connections shorter than the longer VEVOR model, while the mixed-end arrangement makes connection style especially important. The tractor side is 1-3/8-inch six-spline, but the implement side is 1-3/8-inch round, so both ends need to match the equipment. A 20CrMnTi carburized-steel universal joint and Q345 steel tube are specified within the shield, supporting its stated use with agricultural machinery.
- 30-to-39-inch range
- 1-3/8-inch six-spline tractor end
- 1-3/8-inch round implement end
- 20CrMnTi joint and Q345 steel tube
- The round implement end limits it to equipment with that connection style.
Skip it if you need six-spline ends on both sides; the YIHETOP T1 27-35-inch shaft has dual six-spline fittings.
This shaft suits a Series 4 replacement where the tractor connection is six-spline, the implement connection is round, and the span falls between 30 and 39 inches. The mixed ends are its key fit boundary.

10. CHEDA T4 Slip-Clutch Shaft
- Weight: 34.8 lb
Best for: Steel slip-clutch replacement.
Why it ranks #10: This Series 4 shaft is listed at 31.5 to 41 inches with a slip clutch, but its description provides fewer specific capacity details than the other clutch option.
CHEDA’s T4 shaft combines a listed slip clutch with a 31.5-to-41-inch range, giving buyers a Series 4 replacement option for equipment using 1-3/8-inch six-spline connections at both ends. Its high-strength steel construction and powder-coated finish are specified for demanding environments.
The title’s 31.5-to-41-inch range helps buyers assess whether the shaft can bridge their tractor and implement, while the six-spline, 1-3/8-inch ends define the connection style. A slip clutch is also specified, which may be a deciding feature for buyers seeking that configuration. The product description identifies high-strength steel, precision cutting, and a powder-coated finish, tying its construction to the stated goals of resisting deformation and rust in tough environments.
- 31.5-to-41-inch range
- Slip clutch specified
- 1-3/8-inch six-spline ends at both sides
- High-strength steel with powder-coated finish
- At 34.8 pounds, it is a heavy shaft to position during installation.
Skip it if you want a lighter shaft for handling; the SCITOO Yellow 27.5-40.55-inch model weighs 13.17 pounds.
Choose this CHEDA if your equipment needs the stated T4 length range, dual six-spline ends, and a slip-clutch configuration. Its 34.8-pound weight and connection dimensions remain important installation considerations.

View on AmazonAvoiding PTO shaft fit and bind problems
A shaft can appear compatible by spline size yet still be the wrong fit if its end style or working length differs. The VEVOR Series 4 Shaft and Generic Series 4 Shaft both use a 1-3/8-inch, six-spline tractor end but a round implement end; several other listings specify six-spline ends at both sides. Do not treat those arrangements as interchangeable.
Length creates another trap: a shaft must accommodate the distance between the tractor and implement throughout the equipment’s movement. The listed compressed and extended dimensions are reference points, not proof of safe fit on a particular machine.
Measure the actual connection, check both end profiles, and verify the equipment manufacturer’s requirements before use. A shaft that is too long or lacks adequate telescoping travel can bind; one that is too short may not maintain engagement. The supplied listings do not specify every installation dimension or compatibility detail, so verify those before selecting a replacement.
What the listed capacity figures can and cannot tell you
Capacity figures help compare listed options, but they do not by themselves establish that a shaft is suitable for every implement. SCITOO lists 210 Nm at 540 rpm and 172 Nm at 1000 rpm, while ACZCR lists 460 Nm at 540 rpm and 380 Nm at 1000 rpm. CHEDA’s Series 4 slip-clutch listing states 460 Nm at 540 rpm and 360 Nm at 1000 rpm.
These figures point to distinct rated applications, but the product data does not provide a universal selection method or confirm your implement’s required torque. Series labels also differ: several products are T1, while others identify as Series 4.
Treat series, rotation speed, end connection, and manufacturer requirements as a combined compatibility check rather than relying on one headline rating. If the implement’s required specifications are unclear, identify them from its documentation before choosing a shaft.
How to Choose a Tractor PTO Shaft
Compressed and extended length
Choose a shaft whose dimensions accommodate the tractor-to-implement distance across the operating range. The compact Mkekexe T1-500 is listed at 20 to 24 inches; the Mkekexe T1-680 runs 27 to 35 inches, and the SCITOO spans 27.5 to 40.55 inches. For longer connections, the ACZCR is listed at 39 to 62.5 inches and the VEVOR at 51 to 75 inches.
These ranges serve different installations, not interchangeable use cases. Measure the connection on your equipment and compare it with the shaft’s compressed and extended dimensions.
Buyers with a short, close-coupled setup should look toward the compact end; longer tractor-to-implement distances favour the longer listed ranges, provided the ends also match.
End connections and series
Match both shaft ends and the series to the tractor and implement rather than relying on the 1-3/8-inch size alone. The Mkekexe T1-680, SCITOO, and ECCPP list six-spline ends at both sides, while VEVOR and Generic Series 4 specify a round implement end. The YIHETOP listing describes six-spline ends at both sides.
The products also span T1 and Series 4 designs, so confirm the required series from your existing equipment or its documentation. Buyers replacing a shaft with matching six-spline connections can consider the T1 options; those whose implement requires a round connection need a matching round-end product.
Verify tractor and implement ends separately before ordering.
Listed capacity and included clutch
Compare the listed speed and torque figures with the implement’s stated requirements, and check whether you need a slip clutch. SCITOO lists 16 Hp and 210 Nm at 540 rpm, plus 25 Hp and 172 Nm at 1000 rpm; ACZCR lists 35 Hp and 460 Nm at 540 rpm, plus 55 Hp and 380 Nm at 1000 rpm. CHEDA’s Series 4 clutch shaft includes a slip clutch and lists up to 35 Hp at 540 rpm.
These ratings are not a substitute for your equipment’s specifications. Buyers whose equipment calls for a clutch should consider the clutch-equipped CHEDA option; those with a specific capacity requirement should match the stated figures and shaft series to the implement documentation.
Which Tractor PTO Shaft Should You Choose?
For a typical mid-length setup with 1-3/8-inch six-spline ends on both sides, choose the Mkekexe T1-680: its 27-to-35-inch range and specified T1 construction make it the strongest all-around fit in this lineup. For a compact installation, the Mkekexe T1-500 covers 20 to 24 inches. If you need a wider adjustable span and published torque figures, consider the SCITOO Adjustable PTO Shaft.
Buyers whose equipment calls for a slip clutch can compare the CHEDA Series 4 Slip-Clutch Shaft, listed at 31.5 to 41 inches. For longer setups, the ACZCR Long PTO Shaft reaches 62.5 inches, while VEVOR extends to 75 inches but has a round implement end.
Confirm the actual required length, end type, series, and equipment ratings before choosing.

Frequently Asked Questions
How do I measure a PTO shaft’s required working length safely?
Measure between the tractor and implement connection points with the equipment positioned as it will be used. Shut down the tractor, remove the key, and secure the implement before approaching the driveline. Check the shaft’s required working range through the equipment documentation; a listed length alone does not confirm fit throughout operation.
How can I confirm whether my tractor and implement need a Series 1 or Series 4 shaft?
Check the tractor and implement manuals, existing shaft markings, or equipment labels for the required series. Do not infer the series from shaft length or spline count alone. Confirm that both connections and the required operating range match the replacement shaft before ordering or installing it.
When is a PTO shaft with a slip clutch preferable to one without one?
A slip clutch is preferable when the implement or equipment instructions call for one to help manage sudden driveline loads. Confirm the required clutch type and settings from the equipment documentation. Do not assume that a shaft with a clutch is suitable for every implement or that it replaces safe operation.
Why should I check both PTO shaft end types before ordering?
The tractor and implement connections may require different end types, so check each side against the equipment fittings and documentation. The listed options include shafts with six-spline ends on both sides and shafts with a round implement end. A matching length cannot compensate for an incompatible connection.
What should I verify beyond the shaft’s listed length?
Verify the working-length range, connection types, series, and equipment requirements. The listed range does not establish that a shaft fits every setup, and the product description may specify construction or torque details for some options. Check the tractor and implement documentation before selecting or using a replacement.
Final Words
For a common 1-3/8-inch, six-spline pairing and a mid-length installation, the Mkekexe T1-680 is the strongest starting point, with its listed 27-to-35-inch range and stated construction. Choose the T1-500 for a compact installation, or compare the longer and slip-clutch options when your setup calls for them. Before ordering, verify working length, end type, series, and equipment requirements; the listed dimensions alone cannot establish fit.
