Description
When your implement’s PTO shaft doesn’t match your tractor’s output, work stops until you find the right adapter. This splined adapter bridges the gap between your tractor’s 21-spline PTO and older implements that use 6-spline connections, letting you get back to the job at hand without expensive modifications or new equipment.
What You’re Getting
- Converts 21-spline female input to 6-spline male output in one simple piece
- Extends your PTO by 4-1/2 inches for better implement clearance
- Heat-treated alloy steel construction handles the torque without slipping or breaking
- Set screws secure the connection so it won’t work loose during operation
- Rust-preventative finish keeps it looking good and working smooth season after season
Built for Real Farm Work
This adapter is designed for tractors up to 75 PTO horsepower, making it perfect for mid-size operations running rotary cutters, finish mowers, tillers, and other 540 RPM implements. It’s especially handy when you’ve upgraded to a newer tractor but still have perfectly good older equipment that won’t connect directly.
Made to Last
Farm equipment adapters take a beating from constant vibration, weather, and the full torque your tractor can deliver. This one’s built from heat-treated alloy steel with precision-machined splines that ensure full contact and maximum power transfer. The rust-preventative coating protects against moisture and road salt.
Installation Notes
Clean both the tractor’s PTO shaft and your implement’s input thoroughly before installation—dirt or old grease prevents proper seating. The set screws need to be snug but not overtightened, which can distort the adapter. Always double-check that everything’s secure before you start work, and remember to keep PTO shields in place for safety.
