I really don't know a lot about them or have much experience which is why I was asking you guys. I played with a D8 for a couple hours one day but that is the extent of my experience. I've run plenty of large tractors, bobcats, and uni loaders, obviously not as large or powerful as a dozer. I understand a dozer can be dangerous and has a learning curve but lets be realistic, it isn't rocket science look at some of the guys operating them! I have a good friend that is a Cat mechanic that has offered advice along with a good friend that is a wal mart construction contractor manager and my neighbor that has a D7 and some type of JD track loader. I wanted to pool all the thoughts and ideas together to get a nice variety. Hiring it done is not going to happen. What fun is that? Call me crazy but I like doing hard work on my land and learning new things. I feel much better and more satisfied knowing that I did it. Plus I want to do it right at my pace. I can't really hire it all done and have every section of fence ripped out at the same time. Drivers might not like my cattle all out on the roads and highways
