PTO Extender Adaptor Female 21 & 1-3/8" Male 6 & 1-3/8" Spline For 70HP Engine

PTO Extender Adaptor Female 21 & 1-3/8" Male 6 & 1-3/8" Spline

This PTO extender adaptor features a female 21-spline 1-3/8" input and a male 6-spline 1-3/8" output, designed to extend the power take-off shaft for 70HP engines, enabling connection of implements with different spline counts.

Overview

This PTO extender adaptor with female 21-spline and male 6-spline 1-3/8" connections bridges spline mismatches and adds length to tractor PTO shafts. It is built for 70HP engines and heavy-duty use, allowing operators to attach implements like rotary cutters, finish mowers, and post hole diggers that require a 6-spline input. The robust steel construction ensures reliable power transfer and long service life.

Built For Performance

• Female 21-spline 1-3/8" input mates to standard tractor PTO shafts
• Male 6-spline 1-3/8" output connects to 6-spline implements
• Extends PTO length for better implement clearance

Specs At A Glance

Good To Know

Q: Will this adaptor work with my tractor's PTO? A: Check that your tractor output shaft has a 21-spline, 1-3/8" female connection and your implement requires a 6-spline, 1-3/8" male input. The adaptor is designed for up to 70HP.

Q: Can I use this extender with a brush hog? A: Yes, as long as the brush hog has a 6-spline 1-3/8" input and your tractor provides a 21-spline 1-3/8" output, this adaptor extends the connection.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
