Ric, I have no problem with an 11year old going out and mowing lawns. I do have a problem with an 11 year old claiming to be a professional. Using a walk behind mower, tractor, Z, string trimmer, blower, go for it. I think thats great. Chain saw, no way. Claiming to be a professional, no way. If he is making 5K a year after expenses, means in my area he needs a liciense and insurance. I would like to see what happens when shoots a stone through a car window or hits something by accident. If you read his posts, you will realize that he has a lot to learn, plus he does not listen to the responses that are posted. I taught for 34 years and have run into many individuals like this and they all think they know it all. I don't even call myself a professional mechanic and I have been rebuilding engines for over 40 years. To bjc, read what is posted to answer your questions and don't question the answers. Most of thhe people here know what they are talking about. They are willing to help those who respect their answers, but will turn off those who they feel talk stupid. Ric and I disagree on things all the time. That does not means either of us are wrong, it just means that there are different ways to solve problems. This comes from many years of listening to all of the answers to our questions. If you feel that you are in the same category as someone who has been doing this for a couple of decades, you may be cool, (as you say in you info) but you're not mature enough to be professional.
