Description
You know the frustration when that older implement won’t connect to your newer tractor, or vice versa. This adapter converts 1-1/8 inch 6 spline PTO to 1-3/8 inch 6 spline, solving the common mismatch between compact tractors and implements sized for bigger machines. Instead of missing out on that perfect piece of equipment at the auction or leaving an implement sitting in the shed, this handy adapter gets everything working together.
What You’re Getting
- Set screw attachment provides secure connection that won’t slip during operation
- Extends PTO length by 3-9/16 inches to bridge the gap between tractor and implement
- 5-1/2 inch overall length gives you the reach needed for proper hookup
- Direct replacement design – no modifications or special tools required
Built for Real Farm Work
This adapter works great with compact and utility tractors that have the smaller 1-1/8 inch PTO shaft but need to run implements designed for the more common 1-3/8 inch size. Think rotary cutters, finish mowers, tillers, and other standard PTO equipment that you’ll find at farm sales or want to share between different sized tractors. It’s the bridge that lets older implements work with newer tractors or vice versa.
Made to Last
Built from high-strength steel, it handles the full horsepower your tractor can deliver. The set screw design clamps securely to eliminate the play that causes wear and vibration. This isn’t a temporary fix – it’s a permanent solution that’ll hold up to years of regular use in field conditions.
Installation Notes
Clean your tractor’s PTO shaft thoroughly before installation – any dirt or rust prevents proper seating. Always verify the adapter is fully seated and secured before operating. The set screw tightens down to lock everything in place. Many farmers keep one in the toolbox since you typically need it right away to keep working.
