Not too familiar with this machine. But I operated a tigercat 845 harvestor for several years in the late 1990s. The harvestor cuts, limbs, cuts to length and piles the pulp wood . It used a chainsaw. Just on a larger scale. The bar was maybe 30 inches or so. It ran off a small hydraulic motor. It took a lot of power when sawing. The tigercat had tandem pumps so you could drive the tracks while cutting wood. But before we had the tigercat, we used john Deere 690 excavators with larger higher tracks and a fab tech forestry head. When pressing the saw button the tracks would neatly stall and a good load on the engine. So I壇 imagine it takes a lot of power to run the feller buncher. Another guy operating near us at times had feller bunchers. They would grab two and three trees at a time with it and lay them down while the harvestor followed behind to limb it. One buncher could keep two harvestor a going. They have slightly shorter booms. The tigercat shad a single boom cylinder as opposed to two the excavators had which made them smoother and faster. And much better track power. We have smaller wood here and short. And we could cut a couple tractor trailer loads of wood during a 12 hour shift. We ran 24/7
Have not tried the pine cone trick, maybe this winter..
