PTO Increaser Adapter 1-1/8 to 1-3/8 Inch 6 Spline

Description

When you’ve got implements that need a larger PTO shaft than what your tractor’s got, this handy increaser adapter bridges that gap in seconds. It’s one of those simple but essential parts that can save the day when you need to run an implement with a 1-3/8 inch connection on a tractor with a 1-1/8 inch PTO. Instead of hunting for different equipment or costly modifications, just slip this adapter on and you’re back to work.

What You’re Getting

• Forged construction handles the torque and shock loads of real farm work
• Special short design keeps things compact while extending your PTO by 1-1/8 inch
• 6 spline design on both ends fits most common smaller tractor configurations
• Direct fit connection—no set screws or complicated installation needed

Built for Real Farm Work

This adapter is perfect for utility tractors and compact machines up to 75 PTO horsepower that need to run implements designed for larger shafts. Whether you’re connecting a brush hog, rotary cutter, or any other PTO-driven attachment that has the larger 1-3/8 inch input, this increaser lets you use equipment that would otherwise sit idle in the shed.

Made to Last

Farm implements don’t go easy on PTO connections, and this forged adapter is built to handle it. The special forging process creates a stronger, more durable part than cast or machined adapters. It’ll stand up to the constant cycling, vibration, and occasional shock loads that come with agricultural work, season after season.

Good to Know

Installation is straightforward—just slide the female end onto your tractor’s PTO shaft until it seats fully, then connect your implement to the male end. Always engage the PTO at low RPM and gradually bring it up to operating speed. Make sure your implement’s power requirements don’t exceed your tractor’s PTO rating, even with the adapter in place.
