Description
When you need to run an implement with different splines than your tractor’s PTO, work stops until you find a solution. This quick-release adaptor lets you connect 6-spline implements to your 21-spline PTO shaft in seconds, getting you back to the job at hand without the hassle of hunting down different equipment.
What You’re Getting
- Quick-release pin system lets you connect and disconnect implements in seconds
- Extends your PTO reach by 4 3/4 inches for better implement clearance
- Zinc and gold passivate finish protects against rust and corrosion
- Heavy-duty construction rated up to 70 horsepower for reliable power transfer
- Standard 1 3/8″ diameter on both ends fits most common tractor configurations
Built for Real Farm Work
This adaptor works great when you’ve got older implements that don’t match your newer tractor’s PTO setup. Maybe you upgraded your tractor but still have a perfectly good brush hog, finish mower, or rotary cutter with 6 splines. Or perhaps you picked up used equipment at an auction only to discover the spline count doesn’t match. This adaptor solves those common problems without expensive modifications.
Made to Last
PTO adaptors take a beating, handling tremendous torque loads and shock impacts that come with agricultural work. This one’s built from solid materials with precision-machined splines that ensure full contact for maximum power transfer. The protective finish holds up to weather and field conditions season after season.
Installation Notes
Simply slide the female end onto your tractor’s 21-spline PTO shaft and secure with the quick-release pin, then connect your 6-spline implement to the male end. Clean your PTO shaft before installation – any dirt or rust prevents proper seating. Always make sure the adaptor is fully seated and secured before operating.
