Fitting Mower Shear Key Video

Backfiring, no starts, pull cord snapping back violently and oil leaks are all signs that your shear-key is damaged. If you’ve had a blade strike, then it’s very likely you need to watch this video. The good news is a shear-key only costs a few dollars.

Before working on your mower be sure to remove the plug wire to prevent accidental starting, see “Repair Safety Video”.
