Well, I had surgery to repair my left knee and it turns out it was worse than expected. Doc says I have to stop running and lifting weights (legs at least) which I normally do 3-4 days a week. Have to do some biking instead and stick to upper body weight lifting only. If I don't, he says I will need a full knee replacement in 3 years. As it is I have almost no cartilage left in my knee. Now, the real problem. He suggested ditching the 48" w/b mower for a rider of some sort. I know a ZTR would be the ideal, but I can't afford one this year or next. I mow and landscape part-time in order for my wife to stay home with our 2 boys. I'm a teacher full time. I know I could go with a sulky, but I do mostly small yards (1/4 acre or so) and the engine on my Bobcat w/b is only a 13 hp Honda. Cuts great, but I'm a 230 pound weight lifter. I don't think it's going to be pulling me around and up and down hills all that great. If I'm wrong on that, let me know. So, I figure the only other option is to sell the w/b. I could get about $1200 for it. What could I get that would allow me to sit or stand for that money. Only thing I see is a regular old rider. Anything esle? How much slower will I be with a rider compared to the w/b? I intend to stay in business one way or another so please make any suggestions that you think may help. Thanks guys.
