upgraded PTO extender adaptor for tractor with female 1 3/8 inch 6 spline and male 1 3/8 inch 6 spline What it does Converts and extends standard tractor PTO connections that use 1 3/8 inch 6spline shafts. Provides a direct, positive spline connection between tractor and implement when lengths or couplings do not match. Installs between the tractor PTO and the implement shaft with no permanent modification to either component. Key benefits Compatibility: Works with tractors and implements that use 1 3/8 inch 6spline PTO shafts on both ends, allowing quick conversion and extension. Trouble connection: Precision spline engagement reduces play and improves power transfer compared to improvised adapters. Saves time and money: Avoids costly shaft replacement or custom fabrication by providing an offtheshelf extension and conversion solution. Durable performance: Upgraded design improves fit and longevity for routine field and yard work. Important attributes Function: PTO extender and adaptor for extending reach and matching male to female 1 3/8 inch 6spline shafts. Compatibility: Designed for standard 1 3/8 inch 6spline tractor PTO systems and compatible implements. Size and fit: Female 1 3/8 inch 6 spline on one end and male 1 3/8 inch 6 spline on the other end for onetoone spline matching. Performance: Precision spline engagement for reliable torque transmission and reduced backlash. Typical applications Lawn and grounds maintenance: Extend reach to connect a rotary cutter or flail mower when the implement shaft is slightly short of the tractor connection. Farm and tillage tasks: Connect tillers, cultivators, or seeders that require a simple extension between the tractor PTO and implement shaft. Winter and property maintenance: Use with snow blowers or brush cutters when implement positioning requires additional shaft length. Use tips Confirm both tractor and implement use 1 3/8 inch 6spline PTO shafts before installation. Secure any retaining pins, collars, or safety shields according to implement instructions after fitting the adaptor. Check spline engagement and driveline alignment before applying full load. Who should consider this adaptor Farmers, landscapers, rental operators, and property managers who need a reliable way to match or extend standard 1 3/8 inch 6spline PTO connections without modifying equipment. The upgraded PTO extender adaptor provides a straightforward, compatible solution for matching and extending 1 3/8 inch 6spline tractor PTO connections, improving fit and power transfer for common agricultural and maintenance implements.
