Description

Sometimes your implement’s PTO shaft doesn’t quite reach where it needs to be, or you need to clear a tight spot between your tractor and attachment. When that happens, this handy extension adapter bridges the gap and gets your equipment lined up properly. Extending your PTO length by 2-15/16 inches, it’s a simple solution that keeps you working instead of wrestling with mismatched connections.

What You’re Getting

  • Direct 1-3/8 inch 6-spline connection on both ends—no guessing about fitment
  • Set screw attachment that clamps securely to prevent slipping under load
  • Built for tractors up to 75 PTO horsepower, handling the power your mid-size equipment delivers
  • Nearly 3-inch extension length that solves most spacing problems without excessive overhang

Built for Real Farm Work

This adapter works with any tractor or implement using the standard 1-3/8 inch 6-spline PTO setup, which covers most utility and mid-size farm tractors. Whether you’re running rotary mowers and brush hogs, rotary tillers and cultivators, hay balers and tedders, manure spreaders, post hole diggers, wood chippers, or irrigation pumps, this extension gives you the reach you need to make stubborn connections work.

Made to Last

Built from high-strength steel, it handles the full horsepower your tractor can deliver. The precision-machined splines ensure full contact for maximum power transfer, while the set screw design eliminates the play that causes wear and vibration in looser fittings.

Installation Notes

Clean your tractor’s PTO shaft thoroughly before installation—any dirt or rust prevents proper seating. Tighten the set screws evenly to avoid distortion, and always verify the adapter is fully seated and secured before operating—a loose PTO adapter is extremely dangerous. Check that the adapter doesn’t extend the PTO shaft beyond safe operating length—you don’t want to stress your U-joints when turning.
