Frequently Asked Questions

Does this replace 5100915SM, 5100915S, and 5100915?

Yes. This listing covers those replacement references for compatible applications. Match your original clutch number and the installation details before ordering.

Does this replace Warner 5219-34A or 5219-34?

Both Warner 5219-34A and 5219-34 are included in this replacement reference. The same numbers may be written without the hyphen as 521934A and 521934.

Will this fit my Ferris IS 500Z?

This guide lists select 24 hp IS 500Z applications. Check the OEM parts diagram for your complete model and serial number to confirm the original clutch reference.

Does this fit every Snapper, Snapper Pro, or Simplicity zero-turn?

Fitment depends on the original clutch number and mower configuration. Use the specific model and engine references above, then confirm the clutch in the OEM diagram for your machine.

Is any clutch marked Warner 5219 a match?

The complete number matters. For this listing, use the references 5219-34A and 5219-34, then compare the physical specifications and electrical connection.

What bore and pulley size does this replacement use?

The clutch supplied here has a 1-inch crankshaft bore and 6-inch pulley. Compare the pulley offset, rotation, and mounting arrangement as well as these dimensions.

What should I check if the blades click but do not engage?

A click alone does not identify the failed component. Check the clutch’s electrical supply and connector, then inspect the belt drive and deck components. If engagement changes as the mower warms up, include that detail when asking for troubleshooting help.

Can you help identify a clutch with an unreadable label?

Yes. Text 541-361-8778 or email support@ptodirectusa.com with the mower model and serial number, engine information, deck size, and clear photos of the clutch, connector, and mounting area.
