I had this link brought to my attention it has some good information in it on how to build a racing lawn tractor. Keep in mined some of the modification made to this tractor may not be allowed in the class or club you plan on racing in. So double check the rules.
Good site Gary but he is building for a different club with different rules . So for anyone thats veiws the site just remember that we have our own set of rules to build by and if there is any questions just ask. And this guy did a excellent job on that build we can learn from guys like that.
