You are certainly free to believe that a new tractor is the best way to approach 8 acres of logging downed 24" trees but I don't. I have gone over the reasons why I dont' think it is but its' clear that you see this differently and that is fine.
My experience comes from doing actual logging of material this size and running a full sized skidder. Loggers approach things differently than landowners do.
And yest CUT's have tiny small front tires which end up carrying most of the weight when doing loader work. That is a fact. I had a 45 HP tractor and the fronts were severely undersized for carrying loads. When you feel the back of the tractor get light you know that the majority of the weight on on the little front axle.
If you want to believe that backhoes front axles are undersized and the tires not fit to carry heavy loads you are entitled to your opinion. From my experience running construction equipment it is built to a different standard and designed to take a beating doing hard work much more so than a CUT.
A tractor is designed to pull heavy loads so if the OP goes with a tractor I would try to find a way to drag material out as opposed to carrying everything out. That will also allow more flexibility in getting close enough to hook up a chain or cable as opposed to having to drive right no to the downed tree to get it with a grapple. I would leave them whole and then cut them up and use the grapple once you get them out.
We arent gonna get any where arguing with each other.
1st, I never said a new tractor was the best idea. And never argued against a used tractor. A used tractor loader would be a good combo, especially if 4wd. But since day one of ownership of a new tractor, and a newer gently used tractor, mine has been in the woods with me cutting wood. So I have nothing against that.
2nd, I never said anything about axles. Your earlier comment was about tires. The
M6060 the op has looked at, comes with 9.5-24" tires. Which is LARGER than anything you will find on a backhoe except for the the ones like JCB. I have a 18000# backhoe, I understand fully the difference in how construction equipment, and ag/utility tractors are built.
This isnt meant to be a debate between what is better at logging type work. Clearly, a skid loader, or other construction/forestry type equipment is king.
My point is, we are talking about a small 8 acres, one time, that is in no rush to get done. And there are a vareity of other tasks that he needs for his property. That $75 tracked skid loader with grapple is not gonna mow his 20 acres. A
M6060, or similar new OR used tractor WILL. And it will ALSO handle his small 8 acres of clearing needs. Sure, not as well as other equipment. But whenever getting equipment to do multiple jobs, there are always trade offs and compromises.
If money were no object, I'd own about a dozen more pieces of equipment myself. But reality is different. For me, a tractor covers the broadest spectrum of tasks that I need accomplished. I feel the OP's situation is similar. In that if he were to get a tracked loader, either new or used......he would still need a tractor. And be left with a seldom used piece of equipment once the 8 acres is cleared.
