“The first step is to remove the motor from the lawn mower base.
Typically, there are 3 or 4 bolts holding the motor to the base, but before you remove them, you will need to remove the mower blade and the shaft coupler that holds the blade on the motor shaft.
Getting the blade and the coupling off is a bit of a pain.
Removing the blade is not nearly as difficult, but still requires a bit of ingenuity to figure out a way to “jam” the blade so it won’t rotate while you remove the bolt which holds it in place on the motor shaft…”
