Track skidders
Thats a big ass load of wood. You don't see loads like that around here.
Also that tracked skidder would go with a big load, but the wheeled skidder would be a lot faster and quicker. The tracked skidder might be better in extreme terrain but thats all. But the tires will go ever the stumps much beter.
The older clark grapples would not go with a realy big load, they were not balanced up good enough or somting, but I know of a local contractor had a couple 667s and the Internationals he had befor would pull much more. Although the newer Ranger skidders maybe improved.
