Metric QD Over-Running Clutch Pto Yoke, 1-3/8"-6Spline B&P 4-Series & 2300-Series

Metric QD Over-Running Clutch Pto Yoke, 1-3/8"-6Spline B&P 4-Series & 2300-Series

The Metric QD Over-Running Clutch PTO Yoke (1-3/8" 6-spline) is designed to protect tractors and driveline systems by allowing implements with rotating mass to free-wheel to a stop when PTO power is reduced or shut off. By preventing the implement from back-driving the tractor once the PTO shaft stops, this clutch improves control and reduces driveline shock in the right applications. Built for B&P 4-Series and 2300-Series compatibility, it uses a Spring-Lok connection and is rated for solid horsepower transfer at both 540 and 1000 RPM PTO speeds.

Ideal For

• PTO-driven implements with large rotating mass that need free-wheeling capability
• Applications where preventing tractor back-drive improves safety and driveline control
• Replacing worn overrunning clutches on compatible B&P 4-Series / 2300-Series drivelines
• Farm equipment setups using a 1-3/8" 6-spline PTO connection
• Operators who need rated horsepower transfer at common 540 or 1000 RPM PTO speeds
