Description
When you’re running a sprayer or other PTO-driven equipment at higher speeds, you need a coupler that can handle the extra stress without failing mid-season. This forged steel roller pump coupler connects your tractor’s 1000 RPM PTO to pumps with 15/16″ shafts, giving you the reliable power transfer you need for demanding field work.
What You’re Getting
- Forged steel construction that won’t crack under the higher torque of 1000 RPM operation
- Set screw attachment design for secure pump connection that won’t slip during operation
- 21-spline 1-3/8″ tractor shaft connection fits standard 1000 RPM PTO systems
- Direct replacement for Hypro equipment—no modifications or special tools needed
Built for High-Speed Applications
This coupler is designed for tractors running pumps at speeds up to 1000 RPM, which is common on modern sprayers and other high-flow equipment. Whether you’re covering ground with a field sprayer or running hydraulic pumps on specialty equipment, this coupler handles the increased rotational speed without the vibration and wear issues you’d get from lighter-duty alternatives.
Made to Last
The forged steel construction means this coupler can take the punishment that comes with high-speed PTO work. Unlike cast or machined alternatives, forged steel maintains its strength even under the shock loads and constant vibration that come with field equipment operation.
Installation Notes
The set screw design makes installation straightforward—just slide it onto your pump shaft and tighten the set screws. Make sure the pump shaft is clean and free of burrs before installation, and use thread-locking compound on the set screws to prevent loosening during operation.
