If I could build one the size of your old struck or garden tractor size that would be perfect. It would mostly be used for grading my property and maybe a few other purposes. I find myself having to get a load of 20 tons of gravel every spring to grade my long laneway and it would really make the job that much easier. I've seen some people converting lawn tractors to mini dozers which could serve my purpose as well. While looking online I read many forums and people were talking about the ubuildit.com website where you could purchase plans for tractor to dozer conversion but that company is now defunct. I guess any plans would help me out.
