Description
Ever bought a great piece of used equipment at auction only to find it won’t hook up to your tractor? Or maybe you’ve upgraded to a bigger machine but still have implements sized for your old tractor. This adapter bridges that gap, letting you connect smaller 1-3/8 inch implements to tractors with the larger 1-3/4 inch, 20-spline PTO shafts. It’s the kind of problem-solver that saves you from expensive modifications or missing out on good deals.
What You’re Getting
- Converts 1-3/4 inch, 20-spline female connection to 1-3/8 inch, 6-spline male output
- Clamp-type design with allen head bolts provides secure, vibration-free connection
- Extends your PTO by 4-15/16 inches to clear any clearance issues
- Rated for tractors up to 125 PTO horsepower – plenty for most farm operations
- Includes the mounting hardware you need to get connected
Built for Real Farm Work
This adapter is perfect for mid-size and larger tractors that need to run older or smaller implements. Whether you’re hooking up a rotary cutter from your previous tractor, running a post-hole digger you picked up used, or connecting any implement with the standard 1-3/8 inch PTO input, this adapter makes the connection possible.
Made to Last
The clamp design beats slip-on adapters every time – no play means no vibration and hammering that wears out your equipment. The allen head clamp bolts create an even, secure grip that stays tight through hours of operation. Built to handle the power your tractor puts out without slipping or breaking under load.
Installation Notes
Installation is straightforward with the two 3/8-24 x 1-3/4 inch allen head bolts and lock washers. Clean your PTO shaft thoroughly before clamping on – any dirt or rust prevents proper seating. Tighten the clamp bolts evenly to avoid distortion, and always double-check that everything’s secure before you start working.
