The one word answer below sums it up unless you want to spend a lot of money on heavy duty equipment. Depends on what you are using, for instance Servis-Rhino and others manufacture rotary cutters for higher HP tractors that are supposed to be able to deal with small diameter trees, no idea on how those perform, but have seen the literature showing those ratings We have overgrown fields with various similar and larger size trees in them now, just from clearing the edges to keep access, with a 45 hp tractor and regular 6 foot rotary cutter, it's nasty business, not even attempt a tree in those diameters and most saplings I knock over with the loader, raise the mower as high as it goes, to avoid the trunk, and ease into the bent over tree, it still sounds like you're hitting a landmine, when that tree springs up in to the blades, pieces can fly out, plus the shock loads to your equipment, not worth doing, better to clear with a chainsaw I think, just cut em low, flush to the ground, then stockpile, won't take that long for stumps that size to rot, unless they're like locust or something. I clear around the stump with an intrenching tool to get as low as possible and not hit dirt with the saw chain. It gets ugly whenever I get into that stuff, things spring up, poke at you, trees that bend over, ride up between the wheels, wheels ride up onto bent trees, safety hazards are more than abundant and quick to get you. Some trees bend over, still attached and will hav spear like ends on them, don't ever run back through a fresh cut area, kind of have to stay in one direction or it gets real dangerous. Here is what Asplundh uses to clear power line easements, it makes short work of trees those size, they still have to ease into them, but they avoid hardwoods over 6"-8" is what the operator told me, so usually the tree cutters get any problem trees first. I watched this thing toss firewood size chunks 100 feet.

Here is what happened to a guy mowing some rough terrain, by himself, just over the hill from us, not sure whether he did not walk the area, what he hit, but he got bumped off the tractor and went under the mower, I use a Ford 850 and a 6 Foot Rhino currently, after hearing about this one, I just about retired from cutting. I just make extra sure to be very careful. I've used this type of mower since I was about 10, 11 years old, know to respect them, but never felt in any danger, safe to say make sure you walk any unknown areas, look for things that can turn the tractor over, new chuck holes, pits, ruts, hidden washouts. Safe to say, just cut em low with a chainsaw, save your equipment, you can cut a lot of small trees in a day. Link loading="auto" style="width:auto;height:auto">
