Description
When you’ve got a mix of tractors and implements, mismatched PTO splines can stop your day cold. Maybe your newer tractor has that 1-3/8 inch 21-spline PTO but you need to run an implement designed for the larger 1-3/4 inch 20-spline setup. This heavy-duty adapter bridges that gap and gets you back to work without hunting around for different equipment.
What You’re Getting
- Converts from 1-3/8 inch 21-spline female to 1-3/4 inch 20-spline male output
- Heavy-duty clamp design that handles up to 125HP without slipping
- Extends your PTO by 4 1/2 inches with a total length of 7-11/16 inches
- Secure connection that eliminates the play and vibration of slip-on styles
Built for Real Farm Work
This adapter is sized for medium to large tractors where you need serious torque transfer. The clamp-type connection means it locks onto your tractor’s PTO shaft and won’t work loose during heavy operation. Whether you’re running a rotary cutter, powering a hay baler, or operating other demanding implements, this adapter handles the load without the wear issues common in lighter designs.
Made to Last
The heavy-duty construction uses quality materials that stand up to the constant vibration and high torque loads of PTO work. The clamp design distributes stress evenly across the connection, preventing the concentrated wear spots that cause other adapters to fail. Built to handle the full power your tractor can deliver.
Installation Notes
Clean your tractor’s PTO shaft thoroughly before installation – any dirt or grease buildup prevents proper clamping. The clamp design tightens down with set screws that need to be evenly tensioned. Always double-check that the adapter is fully seated and secure before you start working – a loose PTO connection is dangerous business.
