Ignition Starter Switch For Exmark Mowers – Replaces 117-2221, 1172221, 137-4100, 1374100

If your Exmark mower won’t crank or the ignition feels funky, this little switch might be all you need.

It’s a brand new ignition starter switch from The ROP Shop, designed to replace part numbers 117-2221, 1172221, 137-4100, and 1374100.

The part number on this one is 100407_3, and it comes with a 1-year warranty.

It’s a straightforward replacement—just swap out the old one and you’re back in business.

Quick heads-up: it comes with a Prop 65 warning because, well, California requires that on pretty much everything.

But if you’re just trying to get your mower running again, this is the part to grab.
