Description
If you’ve got a Ford NAA Jubilee and you’re trying to run modern implements that need the standard 1-3/8 inch PTO shaft, you’ve probably discovered that your tractor’s original NAA710B shaft has different splines. This conversion piece solves that problem by letting you run today’s equipment on your classic Jubilee without having to hunt down vintage implements or modify anything.
What You’re Getting
- Converts your NAA710B shaft to the standard 1-3/8 inch spline configuration that modern implements use
- Direct bolt-on installation – no modifications needed to your tractor
- TISCO quality construction that handles the torque your NAA can deliver
- Gets you access to the huge selection of current 540 RPM implements instead of being stuck with hard-to-find vintage equipment
Built for Real Farm Work
This adapter is designed specifically for Ford NAA tractors (the famous Jubilee model). Whether you’re running a brush hog, finish mower, or tiller, this conversion lets your classic Ford work with the implements you can actually find and afford today.
Made to Last
TISCO builds their parts to handle farm work, and this conversion piece is no exception. It’s machined to precise tolerances and built from materials that won’t twist or wear out under the loads your implements put on it.
Good to Know
Installation is straightforward if you’re comfortable working on PTO systems. Clean the splines thoroughly before installation and use a light coat of grease to prevent corrosion. Always verify the adapter is fully seated and secure before operating any implement – a loose PTO connection is dangerous. Note that this is a while-supplies-last item, so if you need one for your Jubilee, don’t wait too long.
