Adjustable PTO Extender for 1 3/8 in 6 Spline Shafts Keep implements connected and running without replacing the whole PTO shaft. This adjustablelength PTO extender bridges length differences quickly and reliably, and is compatible with Pats 3point quick hitch system for faster implement changes. Key benefits Solves shaft length mismatches: Adjusts to the required length so you avoid costly shaft replacements or extensive modifications. Secure, seamless connection: 1 3/8 in 6 spline to 1 3/8 in 6 spline design provides a tight fit with common tractor PTOs and implements. Protects driveline components: The 6 spline interface reduces wear on transmission parts, helping extend component life and lower maintenance needs. Easy to install: Follow a few simple steps to swap adapters and get back to work with minimal downtime. Specifications and function Spline size: 1 3/8 in 6 spline input to 1 3/8 in 6 spline output. Function: Extends or adapts PTO shaft length while maintaining spline compatibility and torque transmission. Compatibility: Works with a wide range of tractors and implements that use the 1 3/8 in 6 spline PTO connection and is compatible with Pats 3point quick hitch system. Simple installation steps 1. Shut off power and ensure equipment is secured. 2. Remove the old adapter or extender. 3. Apply appropriate lubricant to splines if recommended by the implement manufacturer. 4. Install the extender, secure retaining hardware, and check alignment. 5. Test connection at low speed to confirm secure engagement before normal operation. Typical use scenarios Field mowing: Use when switching from a short PTO shaft mower to a tractor with a longer hitch setting to restore correct shaft engagement. Tillage and seeding: Connect implements such as rotary tillers or seeders when hitch position changes create a length gap. Quick hitch implement changes: Combine with a 3point quick hitch system for faster, safer implement swaps while maintaining proper PTO engagement. Why choose this extender This PTO extender focuses on reliable mechanical compatibility and straightforward operation. Its 1 3/8 in 6 spline design maintains proper torque transfer and reduces wear on driveline components, while the adjustable length eliminates the need for expensive replacements when equipment geometry changes. Note: Always follow tractor and implement manufacturer recommendations for lubrication, safety, and installation procedures.
