Frequently Asked Questions

Does this replace the Warner 5217-9 on my Troy-Bilt?

Yes, this replacement covers the listed 5217-9 / 1772388 applications. Compare the 1-inch bore, 5.35-inch pulley, mounting arrangement, and connector with your original assembly.

Why does my parts diagram show 1772388 instead of 917-1459?

1772388 is the earlier clutch number in the listed LTX diagrams. The current service replacement is identified as 917-1459.

Should I use the tractor number or mower deck number?

Use the tractor model and serial number, along with the original clutch label. This PTO clutch is mounted at the engine. A deck number such as 14112 is useful for deck parts but does not identify the clutch by itself.

Will the wiring plug straight in?

Only if your mower harness has the matching T-plug connection. A flat, side-by-side connector requires an appropriate adapter or wiring modification. Send a connector photo to our Parts Desk if you need help checking it.
