$10 For An Electric Mulching Lawnmower

Over the last couple years I’ve rolled home 2 or 3 lawnmowers whose owners placed them on the curb on trash-day eve.  Upon finding no obvious way to repair them, back to the curb they went.  Recently a neighbor offered me a mulching mower for free.  It looked to be in very good condition. He said something was broken and preventing it from coming on, but he thought I could fix it.  I had no idea that my skills were so widely known.

The moral of the story: A basic familiarity with spare parts, tools, and basic mechanics can save you lots of money.

I need to remember to thank my neighbor and tell him how glad I am to have the mower.  Who knows what else he might need to find a home for?
