Pump Drive Adapter with 1-3/8 Inch 6 Spline Female and 5/8 Inch Round Ends

Description

When you’ve got a hydraulic pump that needs to connect to your tractor’s PTO but the splines don’t match, work stops until you find the right adapter. This handy pump drive adapter solves that problem by converting your tractor’s 1-3/8 inch 6-spline output to a 5/8 inch round connection, letting you run auxiliary pumps and hydraulic equipment without expensive modifications or custom fabrication.

What You’re Getting

• Female 6-spline end fits standard 1-3/8 inch tractor PTO outputs used on most agricultural tractors
• 5/8 inch round female end connects to hydraulic pumps and other round-shaft equipment
• Solid keyway attachment provides secure connection that won’t slip under load
• 4-11/32 inch length gives you just the right reach for most applications

Built for Real Farm Work

This adapter is perfect for connecting auxiliary hydraulic pumps to your tractor’s PTO system. Whether you’re running irrigation pumps, post hole diggers, or other hydraulic equipment, this adapter handles the conversion so your equipment works together smoothly. It’s designed for the 540 RPM speed that most agricultural implements use.

Made to Last

Built from heat-treated alloy steel, this adapter is designed to handle the torque and shock loads that come with agricultural work. The precision machining ensures solid connections on both ends, while the durable construction resists wear from constant engagement cycles and exposure to farm conditions.

Good to Know

Clean both PTO connections thoroughly before installation—any dirt or grease buildup prevents proper seating. The keyway attachment requires proper alignment for secure fit. The splines should slide together smoothly without force – if you have to hammer it on, something’s wrong and you risk damage.
