So I bought my house in November, and now realize it's time to mow the lawn here in northern Virginia. I have three rusty and visibly busted hunks of push lawnmowers my prior owners abandoned in my back yard. I'm sure I could throw new fuel and plugs in one of them in hopes of getting it started, but is it really worth it? I just don't want to put money in a hole, if I come to find out that once one runs again it does a bad job. How can I assess my ill-repaired mowers for potential vs abandonment?
