I'm just getting started in the lawn care business. I have 3 sons, 2 of them of an age that they are enthusiastic about helping, and I'm doing this in addition to my full-time job. I have approximately $1500 to invest in equipment to start out with. I will be mowing a nature trail around our lake, our community area, and rights of way. All told, it's probably about 8 acres of mowing. What I would like to know is this: 1. What kind of mower is best for these needs? 2. Is it okay to buy from a Wal-Mart or SAM'S? 3. Is it worth it to consider buying used? 4. What is a good brand/model of trimmer to buy? Gentlemen, I've been talking about doing this for years. I am know going to do it and intend on doing it for quite some time. I appreciate any advice that you can and will give me.
