Upgraded PTO Extender Adapter for Tractor, 1-3/8" & 6 Spline Female & Male 70HP

PTO Extender Adapter for Tractor

Heavy-duty PTO extender adapter that shifts the tractor's power take-off connection point outward to improve driveline alignment; cross-references common 1-3/8-inch 6-spline female-to-male dimensions.

Overview

This PTO extender adapter provides a solid inline extension for tractor PTO shafts, allowing implements with shorter drivelines to reach the tractor stub without binding. Designed for farm tractors, rotary cutters, and finish mowers that rely on a 1-3/8-inch 6-spline interface, the PTO extender adapter handles up to 70HP and preserves smooth power transfer. The PTO extender adapter is machined to slip onto the existing PTO output and deliver a reliable female-to-male conversion.

Built For Performance

• Precision-cut 1-3/8-inch 6-spline internal and external profiles maintain full spline engagement
• Heat-treated alloy steel construction resists twisting under 70HP peak loads
• Black oxide finish slows corrosion in wet field conditions
• Extended barrel length creates clearance for wide implement yokes
• Smooth machined bore reduces vibration at PTO operating speeds

On-The-Job Use

• Extends PTO reach on brush hogs when the tractor drawbar sits far back
• Adapts older implement drivelines to modern tractor PTO stub lengths
• Prevents yoke interference on compact tractors running rear-mount snow blowers
• Converts a female PTO driveline to a male tractor output without replacing the entire shaft
• Bridges gap on tillers and post-hole diggers that require extra clearance behind the lift arms

Specs At A Glance

Good To Know

Q: Does this extender change PTO operating length? A: Yes, it adds roughly 4 to 6 inches to the overall driveline length, so measure your existing shaft travel before installing to avoid bottoming out the telescoping section.

Q: Will this fit category 0 and category 1 tractors? A: It fits any tractor with a standard 1-3/8-inch 6-spline PTO stub, which covers most modern compact and utility machines up to 70HP, but always match your spline and diameter before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
