Description
When you’re running spray equipment or any pump-driven implement, that little coupler between your tractor’s PTO and your pump is what keeps everything spinning smoothly. If yours is worn out or making noise, you’ll know it—and so will everyone in the next field over. This forged steel coupler gets your Hypro roller pump talking to your tractor’s PTO the way it should.
What You’re Getting
- Forged steel construction that handles the torque and vibration of pump operation without cracking or wearing out
- Set screw attachment design for a secure, no-slip connection to your pump’s 5/8 inch shaft
- Standard 1-3/8 inch 6-spline design fits most 540 RPM tractor PTO systems
- Direct replacement for your worn coupler—no modifications or special tools needed
- Precision-machined splines ensure smooth power transfer and long service life
Built for Real Farm Work
This coupler connects your tractor’s standard 540 RPM PTO to Hypro roller pumps used in spraying operations, liquid fertilizer application, and other agricultural tasks where reliable pump operation is critical. Whether you’re spot-spraying weeds, applying liquid nitrogen, or running a wash-down system, this coupler handles the constant starting, stopping, and varying loads that come with the job.
Made to Last
Pump couplers take a beating from constant vibration, temperature changes, and the shock loads that happen when you engage the PTO. This one’s forged from high-strength steel rather than cast, so it resists stress cracking and holds up to the demands of commercial and agricultural use. The heat-treated steel maintains its strength even after thousands of hours of operation.
Good to Know
Installation is straightforward—slide the coupler onto your pump shaft and tighten the set screw securely. Make sure both the pump shaft and coupler are clean before assembly to prevent slippage. A drop of thread locker on the set screw helps keep things tight through all the vibration. Always engage your PTO slowly when starting pumps to avoid shock loading the coupler.
