For the money, you can buy a a much better dozer like the Mitsubishi or a used Cat, Deere or Case. The problem with that dozer is very smiple, it's too small to do anything useful.
Taking out a small sapling is within it's range, but you can do just mow those over with a good sized bush hog. If you take them out with such a small dozer, then you are way underpowered and too light to move them, except for just a few at a time.
Knocking over trees isn't all that hard, but getting rid of them is very labor and time intensive. Having a tractor that is too small for the job just makes it just about impossible to accomplish.
You have enough land that you need a real dozer, not a toy. I would think at a very minimum, you need 80 hp. That is still a small dozer, but at least it will get some land cleared and they sell pretty quickly.
Trying to get rid of the Nortrac Dozer when you realize it's too small, has no power and starts breaking down can be very dificult. Especially if you break something on the dozer.
My dozer is medium sized and pretty good at clearing timber and digging clay. It's also very fragile and when put up against trees on a daily basis, the trees win at least once a week. Sometimes several times a week.
I can get just about any part from my dealer either that day, or the next. Can you say the same about this dozer? If it breaks down in the middle of your woods and the weather is gonna get nasty, can you be sure you can get it fixed in a day or two? In a week or two? Or will it be there for months?
Dozers are not toys once you own them. They are money pits that can do what nothing else can. The bigger the dozer, the faster and easier it can do this job, but you need a minimum amount of power. The Nortrac is not even half of what you need to do anything practical.
