When you’ve got a tractor with the big 1-3/4 inch 20-spline PTO and need to run an implement with the smaller 1-3/8 inch 21-spline shaft, this clamp adapter does the job. This is exactly the kind of situation that comes up when you’re running newer equipment on older tractors, or mixing and matching implements from different brands. The clamp design locks everything together tight so you can get on with your work.
What You’re Getting
- Clamp-style attachment that won’t slip or work loose under load
- Converts from 1-3/4 inch female 20-spline to 1-3/8 inch male 21-spline connections
- Extends your PTO reach by 5-7/16 inches for better implement clearance
- Rated for tractors up to 125 horsepower to handle serious field work
- Uses standard 3/8-24 x 1-3/4 inch allen head bolts with lock washers for secure mounting
Built for Real Farm Work
This adapter bridges the gap between different PTO sizes you’ll find across various tractor and implement brands. It’s designed for tractors up to 125 horsepower, making it suitable for everything from mid-size utility tractors running hay equipment to larger row-crop machines pulling heavy implements. The 8-inch overall length gives you the extra reach you need when clearance is tight.
Made to Last
Built with heat-treated alloy steel and a rust preventative finish, this adapter stands up to the punishment of daily farm use. The clamp design distributes stress evenly around the shaft, preventing the wear and damage you can get with set-screw attachments. The quality construction means it’ll keep doing its job season after season.
Installation Notes
Installation takes just minutes but requires attention to detail. Clean your tractor’s PTO shaft thoroughly before installation – any dirt or debris prevents proper seating. The clamp design uses allen head bolts that should be tightened evenly to avoid distortion. Always double-check that everything’s secure before you fire up the PTO.
