Description
When your tractor’s 21-spline PTO doesn’t match your implement’s 6-spline connection, this adapter bridges that gap so you can get back to work. Whether you’re running newer tractors with older equipment or mixing brands that use different spline configurations, this handy piece solves those frustrating compatibility problems that pop up on every farm.
What You’re Getting
- Converts 21-spline female PTO to 6-spline male output for maximum equipment compatibility
- Heat-treated alloy steel construction handles the torque and vibration of farm work
- Set screws provide secure connection that won’t slip under load
- Extends your PTO reach by 4 13/16 inches for better implement clearance
- Rust preventative finish protects against moisture and weather exposure
Built for Real Farm Work
This adapter works with tractors up to 125 horsepower, covering most utility and mid-size row-crop machines you’ll find on farms today. It’s perfect for connecting implements like rotary cutters, finish mowers, hay equipment, and tillage tools that use the older 6-spline standard to newer tractors with 21-spline PTOs.
Made to Last
Farm equipment takes a beating, and PTO adapters see some of the worst abuse since they’re right in the action. This one’s built from heat-treated alloy steel that won’t twist or break under the high torque loads your implements dish out. The rust preventative coating keeps corrosion at bay even when stored outside.
Installation Notes
The set screws make installation straightforward – just slide it onto your tractor’s PTO shaft and tighten the screws evenly for a secure fit. Clean both the tractor shaft and adapter thoroughly before installation to ensure proper seating. Always check that the adapter is fully secured before engaging the PTO – a loose adapter is dangerous and can damage your equipment.
