Turns out I didn't need it, but I'm keeping it on hand for later use. These 430xh mowers are practically bullet proof, and having the right wear-and-tear parts available makes expensive yard equipment more reasonable over the long term. I've been running my mower since 6/2020, and it's still going strong. This year (2026) is the first time I've needed a few worn out parts, and RMS always has them available, from the smallest screw and washer, to the larger stuff.
