I think there is a bit of misunderstanding regarding when to use a track hoe for clearing land. Not sure if a few of you are relating to my earlier comments, but I thought I'd just clarify exactly what I was saying. What I am referring to, are operations where when done, you are going in with a disc and not waiting for material to rot down.
If you are simply looking to walk and pile, nothing is faster than a cat with dozer. Depending on what time of year and ground conditions and also amount and size of brush or trees, how clean of job is done, that is how much or little dirt is in the windrows is variable. But no question, a cat can walk it down and pile it way faster and cheaper than a hoe of any size can.
However, if the land has been logged, the "handle" has now been removed from the stump, and you now have a large stump sticking 6 inches out of the ground and as any experienced cat skinner knows, even a D8 will either slip over or have grief when encountering a larger stump or two or three at the same time, with the blade, like roughly 20 inches in diameter or larger. Even if done with no frost and a root rake, since there is no way of rolling the stump out as is done with the tree still attached, you end up with a very dirty root ball because the stump is more pushed out, rather than rolled. This is where a large hoe kicks ass. For stumping, they can't be beat for speed of popping stumps out and for the cleanliness of the root ball and piles. In regular bush, after logging, there is virtually nothing large still standing and most under brush is knocked down. After you have removed the stumps with the hoe, you still need to make at least one pass with the dozer, however this can be done now with just a D6 with blade angled walking right along.
A lot of guys try to stump with smaller series hoes, and they are slow and things don't work good at all. There isn't the weight nor the power to in just seconds, with a quick roll of the bucket and drop the thumb, a quick shake as you swing, then throw the stump towards the pile. Like anything, experience counts for how good and quick of job is done. As for using a hoe to actually clear bush, they work good for like doing old fencelines or small areas, but over all, when dealing with standing trees, they are slow compared to a cat, though they do a clean job with next to no dirt in the piles. One place I do use my hoe over the cat for standing brush is doing large clump willows. Usually do them in summer when there is no frost, grab tree and root ball as one and lift. This where a large hoe only works, as now you have dirt moving in a 30 foot circle in front of you as the trailing roots all pull clear. Shake it a few times and throw it in the pile. That takes some serious hydraulic power and weight to pull stuff like that off. What else is good about it, is now there is hardly any roots left in the ground either
I remember reading an article several years ago, from the late Sixties or early Seventies in The Farm Quarterly magazine, ( I have a big box of them my father saved), about using the chain method of clearing land. It wasn't that big of trees they were knocking down, and a couple of other things I remember was the two big swivels at the back of each cat the chain connected to, and every so often there was huge steel balls for weight. The lead cat would run ahead of the trailing one so most of the chain was at about a 45 degree angle. That had something to do with how good it worked. I think it was in Texas or maybe Mexico. The jest of the article was that it was fast way of reducing brush. I might just have to find that box of mags and do a little reading up on that idea and refresh the old memory
