Hypro Power Take-Off Quick Coupler 1321-0006

When the PTO and the pump don't line up, the whole spray day waits. This quick coupler joins the tractor's power take-off to a Hypro 6500 Series pump, with a 1-3/8 inch, 6-spline drive side and a 5/8 inch pump side, so the drive carries power from the tractor to the pump.

It's rated for 540 rpm, the common PTO speed on many tractors. A quick coupler is a practical part for a pump you move between machines or pull off between seasons. Connect it, run the rig and disconnect when the job's done, without wrestling a shaft in the mud.

Why a PTO quick coupler matters

A PTO-driven pump does the heavy work of moving spray, and the coupler is where the tractor's power meets it. A good fit keeps that power steady from the first pass to the last. A quick coupler also lets you move the pump between machines without a fight, which matters on a farm running one tractor and one rig.

It suits the operator with a Hypro 6500 Series pump on a tractor, the custom spray outfit moving one pump between machines, and the owner who wants a spare coupler so the rig isn't parked when a part gives out. The shaft and bore sizes do the matching, so measure before you buy.

How to use it

Measure before you fit it. The drive side and pump side have to match your shaft and pump bore.

1. Check the PTO shaft on the tractor against the 1-3/8 inch, 6-spline drive side.
2. Check the pump-side bore against the 5/8 inch pump side.
3. Slide the coupler fully onto both shafts and tighten the setscrews on the pump side before you turn on the PTO.
4. Run the PTO at the rated 540 rpm.
5. Turn the PTO off before you disconnect, and wipe the shaft clean before you store it.

Good to know

• Keep the PTO shaft guard in place at all times, and never run a PTO without its guard.
• Grease the splines lightly to reduce wear, and keep the coupler clean and dry between jobs.
• Keep the pump on its maintenance schedule, and recheck the coupler fit after each season.
