Im not sure what you are intending to do with the logs. Are you cutting for firewood? Or skidding logs for resale? I cut a lot of firewood here on my property. My woods consists of 90% oak, which is heavy, especially wet. Almost all trees I cut down I'm able to chain the tree where I cut it at the trunk. Drive my bucket under the base of the cut tree and chain it inside the bucket and curl it up a bit to keep it from dragging on the ground. From there I'm able to drag the entire tree just about anywhere I want to go. My machine is a 753 which isnt a big machine by todays standards. But even my old 642 amazed me at how it was able to drag full size oaks.
