When your sprayer pump coupling starts slipping or wobbling, you know it’s time to replace it before you’re stuck in the field with a pump that won’t turn. This forged steel roller pump coupler connects your tractor’s 1-3/8 inch 6-spline PTO shaft to sprayer pumps with 5/8 inch shafts, keeping everything lined up and locked together when you need reliable spraying power.
What You’re Getting
- Set screw attachment system for secure connection to pump shafts – no slipping when you hit thick weeds or tough spots
- Forged steel construction that handles the torque and vibration of roller pump operation without cracking or wearing
- Designed for standard 540 RPM tractor PTO speed – matches the operating range of most agricultural sprayer pumps
- Direct replacement design that fits properly without modifications or adapters
Built for Real Farm Work
This coupler connects to the wide range of Hypro roller pumps used in agricultural and industrial spraying applications. Whether you’re running a boom sprayer for crop protection, spraying fence lines, or applying liquid fertilizer, this coupling handles the daily starts and stops that come with spray season work.
Made to Last
Forged steel construction means this coupling can handle the shock loads and constant vibration that destroy cheaper cast parts. The set screw design provides a solid mechanical connection that won’t work loose like worn splines, and the materials hold up to the chemical exposure that’s part of sprayer operation.
Installation Notes
Make sure your pump shaft is clean and free of rust or chemical residue before installing. Tighten the set screw against a flat spot on the shaft if available, or file a small flat if needed for the best grip. A drop of thread locker on the set screw helps prevent loosening during operation.
