HNeekyr Tractor PTO Extender 1-3/8 Inch 6 Spline Male to Female
This adapter is designed to fit 1-3/8 inch 6-spline PTO shafts, providing a secure male-to-female connection suitable for many tractors and implements. Built to handle up to 70 HP, it aims to deliver reliable performance in demanding agricultural tasks. It’s a practical choice when a robust extension is required for frequent attachment changes. Limitation: ensure exact spline configuration on both tractor and implement to avoid misalignment during operation.
Mkekexe Heavy Duty PTO Extender Adapter
This extender is built to extend PTO shafts with 1-3/4″ 20-spline male to 1-3/8″ 6-spline female connections, offering a longer reach with strong alloy steel and a galvanized finish for rust resistance. It is rated to accommodate up to 125 HP, making it suitable for heavier-duty tasks. Best for users who need a longer extension and higher torque capacity. Caution: check that your equipment uses the corresponding 21-spline to 6-spline interface before purchasing.
Mkekexe PTO Extender Push-Pin Type
Designed for quick-connect needs, this push-pin extender offers 1-3/8″ 6-spline female and 1-3/8″ 21-spline male ends with a 7.5-inch overall length and 4.125-inch extend. It’s suited for tractors around 70 HP and is galvanized for rust resistance. Best for users who frequently swap attachments or require a reliable, fast connection. Limitation: ensure that the 21-spline male aligns with your specific PTO system to prevent binding during operation.
T318 PTO Adapter 6-Spline 1-1/8 x 1-3/8
This adapter increases shaft size from 1-1/8″ to 1-3/8″ with a 3-3/16″ length, suitable for many Ferguson models and similar equipment. It is a practical upgrade when upgrading to a larger PTO shaft is necessary, supporting a range of implements. Caution: verify compatibility with your existing PTO shaft diameter before ordering.
Mkekexe Heavy Duty 1-3/4″20 Spline To 1-3/8″6 Spline
This adapter matches 1-3/4″20-spline female to 1-3/8″6-spline male ends with a length around 7.5 inches, designed for universal compatibility and long service life through alloy steel construction and galvanization. Best for users needing a robust, slightly longer adapter with corrosion resistance. Caution: double-check spline counts on both components to ensure a proper fit.
PTO to Pump Coupler 1-3/8″ 6 Spline to 1″ Round Bore
This coupler adapts a 1-3/8″ 6-spline PTO to a 1″ round bore, suitable for standard 540 RPM PTO setups. It has a compact length of 3-3/4″ and is ideal for light to moderate extension needs when space is limited. Best for compact installations, but may be less suitable for high-torque applications.
T353F 4-3/4″ PTO Shaft Adapter
Increase shaft size from 1-1/8″ to 1-3/8″ with a 4-3/4″ length. Replaces Part Number T353F and fits many Ferguson models. This is a practical upgrade when upgrading PTO shafts to handle more demanding attachments. Caution: confirm the exact model compatibility before purchasing.
Buying Guide: Key Considerations For PTO To Belt Drive Adapters
What to check before buying: compatibility with your tractor’s PTO shaft size and spline count, horsepower rating, and overall extension length. Consider whether you need a male-to-female connection, or a push-pin quick-connect design for faster changes. Galvanized finishes improve corrosion resistance, while alloy steel construction enhances wear resistance and long-term durability. If you use multiple implements, prioritize adapters with universal fit and documented dimensions to avoid misalignment.
Practical Buyer Questions
- What spline size should I choose? – Match the PTO shaft to the adapter: most common is 1-3/8″ with 6-spline. Check your tractor’s manual and implement input to confirm.
- Is there a limit to horsepower? – Many extenders are rated around 70 HP, some up to 125 HP. Choose based on the highest HP of any attached implement.
- Will an extender fit any PTO system? – Not all; verify spline counts, bore size, and overall length to ensure a secure, proper fit.
- Do I need a galvanized finish? – Galvanized surfaces resist rust, increasing service life in outdoor, field conditions.
- How long is the extension? – Review the product length and extension figures to ensure clearance for your setup and safety when operating.
- Can I mix different brands? – Compatibility depends on spline counts and tolerances; prefer adapters designed for mixed-use with your specific brands.
Frequently Asked Questions
- What is a PTO Extender and when would I use one? – A PTO extender increases or reduces the distance between the tractor and implement, enabling better reach and alignment for various attachments.
- Are all PTO adapters the same length? – No; lengths vary, and longer extensions may affect stability and torque; verify compatibility with your machine.
- Can I use a 6-spline adapter with a 21-spline male? – Only if the adapter is designed for that spline configuration; mismatched splines can cause damage or failure.
- Do these adapters require special installation tools? – Most do not; standard wrenches or quick-connect pins are typically sufficient, but follow product-specific instructions.
- What maintenance does a PTO adapter need? – Keep surfaces clean, apply light lubrication to moving parts, and inspect for wear or corrosion regularly.
- How do I determine the correct adapter for my Ferguson model? – Check your implement’s PTO shaft size and the adapter’s listed compatible models; refer to the part numbers in the product description.
