KYBOLT PTO Drive Shaft 1 3/8" PTO Shaft, vs ECCPP PTO Shaft, 37"-59" PTO ShaftFit fo

Quick Verdict

Both KYBOLT and ECCPP offer well-rated PTO drive shafts at similar price points, but they serve slightly different needs. The KYBOLT is the stronger choice for standard 1 3/8" 6-spline applications where a secure round end fit is critical. The ECCPP wins for versatility, with an adjustable length range that fits a wider variety of implements. Choose KYBOLT for reliability on a specific tractor and implement; choose ECCPP if you need to swap between multiple attachments.

Side-by-Side

Where KYBOLT Wins

Precision fit – The KYBOLT is explicitly designed for 1 3/8" 6-spline connections with a round end. This makes it a drop-in replacement for many compact and subcompact tractor PTOs (e.g., Kubota B and L series, John Deere 1 and 2 series). If your implement requires a round-end shaft, this avoids the need for adapters or modifications.

Build quality – With 58 reviews versus 41 for the ECCPP, the KYBOLT has a larger sample size and a slightly higher average rating. Users commonly note that the shaft feels robust, with tight spline engagement and minimal slop—important for reducing wear on tractor PTO stubs.

No length guessing – If you already know your required length, a fixed-length shaft (or one with a narrow adjustment range) is often more durable than an extensively telescoping design. The KYBOLT focuses on strength for a specific application rather than universal fit.

Where ECCPP Wins

Adjustable length – The ECCPP covers 37" to 59", making it suitable for a wide range of implements: bush hogs, finish mowers, rotary tillers, and more. This is critical if you use multiple attachments with different PTO shaft length requirements.

Lower price – At $81.79, the ECCPP is about $7.60 cheaper than the KYBOLT. For budget-conscious buyers, that savings can go toward a PTO shield, shear bolts, or grease.

Versatility – The ECCPP is explicitly marketed for Bush Hog and finish mower applications, indicating it’s built for heavier, wider implements. Its adjustable range also accommodates different tractor drawbar heights and implement hitch positions.

Which Should You Buy

Buy the KYBOLT if you have a compact or subcompact tractor with a standard 1 3/8" 6-spline PTO and need a direct replacement for a rotary cutter, tiller, or mower that uses a round-end shaft. It’s the safer choice for a single, known application.

Buy the ECCPP if you need to swap the same PTO shaft between different implements (e.g., a bush hog and a finish mower) or if you’re unsure of the exact length required. It also makes sense for larger tractors (25+ HP) where implement spacing varies more.

Verdict: The ECCPP offers better value for most users due to its adjustability and lower cost.
