PTO Drive Line,Finishing Mowers/Tillers, 1-3/8" x 6 Spline Quick Detach (Both), 40" - 55", 3 Series

What It Is

This PTO drive line connects your tractor’s power take-off to a finishing mower or tiller, transmitting engine power to the attachment. It’s designed for 3-Series compact tractors with a 1-3/8” x 6 spline quick-detach coupler on both ends, and fits attachments with a driveline length range of 40” to 55”.

Fitment & Compatibility

Before buying, measure the distance from your tractor’s PTO shaft to the attachment’s input shaft (both collapsed and extended) to confirm the 40”–55” range works. This drive line uses a 1-3/8” x 6 spline quick-detach coupler on both ends—check that your tractor’s PTO stub and the attachment’s input shaft match this spline size and type. It’s not brand-specific but is intended for 3-Series compact tractors (e.g., Kubota B/L, John Deere 3 Series, etc.). Verify your attachment’s driveline input is not a different spline (like 1-1/8” or 1-1/4”) or a shear-pin style. Measure the PTO shaft diameter too—some older models may use a 1-1/8” x 6 spline. If in doubt, check your tractor and attachment manuals for OEM part numbers.

Key Things to Know

• Quality concerns: With a 2.0/5 rating from only 1 review, this drive line may have reliability or fit issues. Expect potential wobble, premature wear, or difficulty with the quick-detach mechanism.
• Installation difficulty: Moderate. You’ll need to slide the drive line onto both splines and secure the quick-detach collars. Ensure the locking pins fully engage—loose connections can damage the PTO shaft.
• Length adjustment: The 40”–55” range is likely a telescoping shaft. Confirm your collapsed and extended measurements fall within this range. If too long, it won’t fit; too short, it may bottom out and damage the driveline.
• Not a universal fit: Despite the “1-3/8” x 6 spline” spec, some attachments or tractors may have slight spline variations. Test fit before use to avoid buying a return.

Should You Buy It

Only consider this if you absolutely need a budget-friendly PTO drive line and have already verified your tractor and attachment match the 1-3/8” x 6 spline quick-detach spec and 40”–55” length. Given the poor rating and lack of reviews, expect potential fit or durability issues—if you can, spend more on a known brand or OEM part for a reliable connection.
