Best 1 3 8 Pto Shaft for Farm Implements

#1 · Best Overall

1. VEVOR PTO Shaft

• Dimensions: 40 x 6.3 x 5.9 in
• Weight: 21 lb

Best for: Round-end implement match.

Why it ranks #1: Its 1-3/8-inch six-spline tractor end and round implement end suit buyers who need that specific mixed-end configuration; it is a Series 4 driveline.

A 6-spline tractor end paired with a round implement end is the defining fit here, enabling a connection between equipment with those specific end types. VEVOR lists a 1-3/8-inch standard size, a Series 4 driveline, and CE certification for agricultural machinery use.

The 1-3/8-inch, 6-spline tractor end serves tractors with that connection, while the round implement end suits an implement with a matching round connection; this mixed-end arrangement is the key compatibility check. Inside, a solid 20CrMnTi carburized-steel universal joint and a Q345 steel tube within the shield provide the stated construction. Its 40-inch product length and 21-pound weight are useful planning details for handling and installation, though the listing does not give an adjustable range.

Skip it if you need 6-spline connections at both ends; SCITOO Black 48"-80.5" lists 6-spline ends on both sides.

Choose it for agricultural machinery whose tractor end is 1-3/8-inch, 6-spline and whose implement accepts a round end. Check that mixed-end arrangement before purchase; the listing gives no telescoping length range to plan around.

#2 · Best Slip Clutch

2. DEXSO PTO Shaft

• Dimensions: 32.48 x 9.45 x 906 in
• Weight: 36 lb

Best for: Compact slip-clutch connection.

Why it ranks #2: The Series 4 shaft includes a slip clutch and both 1-3/8-inch six-spline ends, with telescoping adjustment from 31.5 to 41 inches.

A 31.5-to-41-inch telescoping span paired with a slip clutch makes this DEXSO shaft a compact-range option for buyers seeking both length adjustment and clutch protection. The listing specifies matching 1-3/8-inch, 6-spline ends on the tractor and implement sides.

The stated compressed and extended lengths give buyers a defined window for checking connection spacing before installation. Both ends are 1-3/8-inch by 6-spline, so the shaft is aimed at equipment with that same end specification. Its Series 4 construction includes a solid 20CrMnTi carburized-steel universal joint and a Q345 steel tube inside the shield. The slip clutch is another listed feature for buyers who want a clutch-equipped driveline, though no clutch torque setting is supplied here.

Skip it if you need more than 41 inches of reach; SCITOO Yellow 39"-62.5" extends farther.

This suits buyers with dual 1-3/8-inch, 6-spline connections who need a compact adjustable shaft and slip clutch. Measure for a working span within 31.5 to 41 inches; the listing supplies no clutch torque setting.

#3

3. KYBOLT PTO Shaft

• Dimensions: 33 x 7 x 7 in
• Weight: 34.9 lb

Best for: Series 4 clutch-equipped fit.

Why it ranks #3: This Series 4 driveline has a slip clutch, six-spline ends on both sides, and a 31.5-to-41-inch length range for matching equipment.

A Series 4 driveline with a slip clutch and dual 1-3/8-inch, 6-spline ends is KYBOLT’s central proposition, enabling a clutch-equipped connection where both mating ends share that specification. Its stated 31.5-to-41-inch range targets installations that fit within a compact telescoping span.

The 31.5-to-41-inch length range gives a clear boundary for measuring tractor-to-implement spacing, while the matching 6-spline ends simplify the end-type check when both pieces of equipment use 1-3/8-inch connections. KYBOLT lists a solid 20CrMnTi carburized-steel universal joint and a Q345 steel tube inside the shield as part of its Series 4 construction. The slip clutch is specified, but the supplied details do not state its torque setting.

Skip it if you require a stated clutch torque rating; SCITOO Black 48"-80.5" lists a 900 Nm slip clutch.

Choose it for agricultural machinery with matching 1-3/8-inch, 6-spline connections and a measured span within 31.5 to 41 inches. Its slip clutch and Series 4 construction are listed, but buyers needing a published clutch torque setting should look elsewhere.

#4 · Round-End Alternative

4. Generic Round-End PTO Shaft

• Dimensions: 39 x 6 x 6 in
• Weight: 19.7 lb

Best for: Short-range round-end driveline.

Why it ranks #4: Its 1-3/8-inch six-spline tractor end and round implement end provide the same useful end-style combination, with a listed 30-to-39-inch range.

A round implement end paired with a 6-spline tractor end gives this shaft a specific mixed-end connection, enabling use where the implement accepts a round end. The listing identifies a 1-3/8-inch size and a 30-to-39-inch range for finish mower and rotary cutter applications.

The 6-spline tractor end and round implement end make connection type the first compatibility check; both must match the respective equipment. Its telescoping tube is described as adjustable, while the title specifies a 30-to-39-inch span to help buyers assess installation spacing. A solid 20CrMnTi carburized-steel universal joint and Q345 steel tube inside the shield are listed as construction details. The product description calls out finish mowers and rotary cutters, but provides no horsepower or torque figures for capacity comparison.

Skip it if you need dual 6-spline ends; ACZCR's 27.5"-40.55" shaft lists 6-spline ends on both sides.

Consider it for a finish mower or rotary cutter setup requiring a 1-3/8-inch, 6-spline tractor end and a round implement connection. Confirm the 30-to-39-inch span works, and account for the absence of listed power ratings.

#5 · Longest Adjustment

5. SCITOO Yellow PTO Shaft

• Dimensions: 39.99 x 6.3 x 5.91 in
• Weight: 24.1 lb

Best for: Adjustable dual-spline driveline.

Why it ranks #5: The both-spline shaft adjusts from 39 to 62.5 inches and lists 35 horsepower at 540 rpm, suiting equipment that needs greater reach.

A telescoping range from 39 to 62.5 inches gives this SCITOO shaft room to accommodate varied connection distances, enabling adjustment around the listed 47-inch recommended working length. Both ends use 1-3/8-inch, 6-spline connections, making matching tractor and implement ends the central fit requirement.

The compressed, recommended, and extended lengths provide a useful starting point for measuring the intended installation, while the telescoping steel tube supports length adjustment. SCITOO lists 35 hp and 460 Nm at 540 rpm, or 55 hp and 380 Nm at 1000 rpm, so buyers can compare the stated ratings with their operating setup. The listing also says the shaft can be trimmed with a cutoff wheel or hacksaw; cut sections must be fully deburred.

Skip it if you need more than 62.5 inches of extension; SCITOO Black 48"-80.5" reaches 80.5 inches.

A practical candidate for buyers measuring a 1-3/8-inch, 6-spline tractor-to-implement connection within its 39-to-62.5-inch range. Keep the 47-inch recommended length and the stated rpm-specific ratings in view when checking the intended setup.

#6

6. YIHETOP PTO Shaft

• Weight: 14.52 lb

Best for: Lightweight dual-spline replacement.

Why it ranks #6: Its 1-3/8-inch six-spline ends and telescoping length of 31.5 to 43.5 inches offer a clearly stated fit for matching connections.

At a listed 14.52 pounds, YIHETOP’s shaft offers a relatively light handling specification alongside a 31.5-to-43.5-inch telescoping range. Its 1-3/8-inch, 6-spline ends on both sides enable connection to matching tractor and tool ends, making end type and working length the key checks.

The minimum 800 mm length and 1100 mm extended total length define the stated adjustment span, also given as 31.5 to 43.5 inches, helping buyers compare it with their equipment spacing. Both ends use 1-3/8-inch, 6-spline connections, described as matching same-size, same-type tractors and tools. The 14.52-pound listed weight may ease handling relative to heavier options, while the supplied details do not provide horsepower or torque ratings for capacity comparison.

Skip it if you need published horsepower and torque ratings; ECCPP lists figures for 540 rpm and 1000 rpm.

A fit to consider for buyers who need dual 1-3/8-inch, 6-spline ends, a span within 31.5 to 43.5 inches, and a listed weight of 14.52 pounds. Check capacity separately because the supplied specifications provide no power ratings.

7. ECCPP PTO Shaft

• Dimensions: 29.53 x 5.71 x 5.51 in
• Weight: 14.26 lb

Best for: Short-span lower-power applications.

Why it ranks #7: The 27.5-to-40.55-inch range and 16-horsepower rating at 540 rpm suit shorter installations with lower listed power requirements.

A compressed length of 27.5 inches makes the ECCPP shaft suitable for buyers whose connection requires a short starting span, with extension to 40.55 inches. Its 1-3/8-inch, 6-spline ends serve matching tractor and implement connections, while listed power figures help define its application limits.

The 27.5-to-40.55-inch range gives a compact adjustment window for checking tractor-to-implement spacing. ECCPP lists 16 hp and 210 Nm at 540 rpm, and 25 hp and 172 Nm at 1000 rpm, which lets buyers compare their operating conditions with the stated ratings. The dual 1-3/8-inch, 6-spline ends provide a specific end-type match. Its listed application references Bush Hog and finish mower use, but the shaft still needs to meet the equipment’s length and rating requirements.

Skip it if you need a higher stated 1000-rpm rating; SCITOO Yellow 39"-62.5" lists 55 hp at 1000 rpm.

This is aimed at buyers needing a short 27.5-to-40.55-inch span and dual 1-3/8-inch, 6-spline ends for a finish mower or similar application. Compare its rpm-specific ratings carefully with the intended operating load.

• Weight: 14.26 lb

Best for: Short-span dual-spline shaft.

Why it ranks #8: This both-spline option shares the 27.5-to-40.55-inch range and 16-horsepower rating at 540 rpm, making it suited to compact setups.

A 27.5-inch compressed length and 40.55-inch extended length give this ACZCR shaft a clearly bounded compact range, enabling buyers to assess short tractor-to-implement spacing. Both ends are 1-3/8-inch, 6-spline, and the listing supplies rpm-specific horsepower and torque figures for capacity checks.

The 27.5-to-40.55-inch adjustment range helps establish whether the connection falls within the shaft’s reach, while dual 1-3/8-inch, 6-spline ends define the required mating connections. ACZCR lists 16 hp and 210 Nm at 540 rpm, plus 25 hp and 172 Nm at 1000 rpm, allowing a more informed comparison with intended operation. Its title names Bush Hog and finish mower applications; buyers should still compare the listed ratings and lengths with their own setup.

Skip it if you require a higher stated 1000-rpm rating; SCITOO Black 48"-80.5" lists 55 hp at 1000 rpm.

This suits buyers needing a compact 27.5-to-40.55-inch span and matching 1-3/8-inch, 6-spline ends for a Bush Hog or finish mower application. Treat its rpm-specific ratings as a boundary when matching equipment.

#9

9. SCITOO Black PTO Shaft

• Weight: 49 lb

Best for: Long-reach shaft with slip clutch.

Why it ranks #9: Its 48-to-80.5-inch range serves installations needing more length, and it includes an adjustable slip clutch rated at 900 Nm.

An 80.5-inch extended length paired with an adjustable slip clutch distinguishes this SCITOO shaft, enabling longer-reach installations with a stated torque-adjustment range. Its 48-inch compressed length and 70-inch recommended use length help buyers assess whether that reach matches their tractor-to-implement spacing.

The telescoping shaft spans 48 to 80.5 inches, with 70 inches recommended for use, so measuring the working connection helps establish whether it falls within the listed range. The slip clutch is rated at 900 Nm, and its adjustment range is listed as 20–55 hp; SCITOO also states 35 hp at 540 rpm and 55 hp at 1000 rpm. The 49-pound item weight is worth considering when planning handling and installation.

Skip it if you need a lighter listed shaft; YIHETOP's 31.5"-43.5" model weighs 14.52 pounds.

Consider it when a long 48-to-80.5-inch span and an adjustable slip clutch suit the job. Check the 70-inch recommended length, the listed power and torque figures, and whether handling a 49-pound shaft works for your installation.

#10

10. Weasler AB1 Driveline

• Dimensions: 34 x 6 x 6 in
• Weight: 11.4 lb

Best for: Fertilizer spreader applications.

Why it ranks #10: This Series 1 driveline has a 27-inch compressed length and cut-to-length adjustability, but the listing specifies fertilizer spreader general applications.

Cut-to-length adjustability and a fertilizer-spreader application focus distinguish this Weasler AB1 driveline, enabling length adaptation for a general spreader setup. It has a 27-inch compressed length, 1-3/8-inch 6-spline specification, and tri-lobe shaft profiles for buyers assessing the connection and driveline design.

The cut-to-length capability lets the shaft be adjusted to a required installation length, while its 27-inch compressed length provides a starting point for measuring available space. Weasler lists tri-lobe shaft profiles and a standard guard; assembly or removal is handled with a screwdriver because the guard is specified without Easy Lock. The listing also identifies fertilizer spreaders as the general application and cites Case OEM replacement number BRW14006127DS, which can help buyers checking that replacement reference.

Skip it if you need a stated extended length before trimming; this listing specifies only a 27-inch compressed length.

A candidate for buyers adapting a driveline for a fertilizer spreader, particularly when the Case replacement reference BRW14006127DS is relevant. Account for its 27-inch compressed length, cut-to-length approach, and screwdriver-operated standard guard.
