My 3 year old lawn mower started making a grinding noise last month
Thought it was the blade at first. Pulled the plug, tipped it over. Blade was fine. Checked the oil, still good. Noise got worse each time I used it. Took off the deck last week to really look. Found the problem. The pulley that drives the blade was shot. Bearings were gone, metal on metal. Local hardware store wanted $45 for a new one. Ordered the exact part online for $18. Took an hour to swap it out with basic tools. Runs quiet now. Anyone know a good way to check those pulleys before they fail completely?

You mentioned checking the oil, but that pulley needs its own check. I give mine a spin by hand when the belt is off, listening for any rough sound or feeling for grit. Catching it early saves the whole assembly.

Yeah, that grinding is a bad sign. I always check for any side-to-side wiggle in the pulley shaft when it's stopped. If it moves even a little, the bearings are going.
