Clamp-On PTO Adapter — 1-3/4" 20-Spline Female to 1-3/8" 6-Spline Male

The Braber 581PA is a clamp-on PTO adapter that converts one PTO spline size to another, letting you connect a tractor and implement with mismatched shafts. It adapts a 1-3/4" 20-spline female end to a 1-3/8" 6-spline male end, and its clamp-on design installs quickly and securely without special tools. Heavy-duty steel construction delivers dependable power transfer.

Bridge Mismatched PTO Shafts

When a tractor's PTO and an implement's driveline don't share the same spline, they won't connect — and that's exactly the problem this adapter solves. The 581PA slips onto a 1-3/4" 20-spline PTO on the female end and presents a 1-3/8" 6-spline male output on the other, so an implement built for a 6-spline shaft can run off a 20-spline tractor PTO. The clamp-on design secures it in place without tools, and its heavy-duty steel build stands up to the torque of real power transfer.
