I'm going to go with a maybe, but I'm not sure I'd try it. .... at least not with the cutting and trying to hold the tree.
I've used a Danuser Intimidator on my
L3560 (very similar to the EA attachment above) to remove smaller trees (<4 inches) and can from experience say they work much better to grab a tree/pole and push/pull while lifting to remove a tree than just holding it. Even small trees may shift in the grapple once free of the ground - or other support.
So personally, I'm not sure I'd want to be working under/near the loader when it's holding some of the larger/heavier size trees you've mentioned. With larger trees when using a chainsaw and a grapple (of any type) it's been a two-person operation: one cutting the tree like the tractor wasn't there, and the tractor just providing assistance to help push the tree where it's aimed. ..... which is still a relatively high risk proposition.
If it's not possible to drop the trees (roughly) parallel to the fence line it may be worth checking to seek if you can rent a boom lift and cut the larger trees down in sections. I say that as depending on the height of the 8" trees not only would the loader be having to lift/hold the weight of the tree, but resist any motion being imparted by the wind on what can effectively be a long-levered sail..... (while the
M7060 is a larger tractor than a
L3560, it's not that much larger despite having ~2x the HP).
...to be honest though just the thought of cutting down a 8" diameter upright live (or dead) tree while holding with my
L3560 is almost a brown-shorts moment itself (at least if it's a tall/slow growing species) -- which is saying something since there's been more than a few times I've lifted long (>25-30ft long) & larger diameter trees from a horizontal --- and have been guilty of lifting the rear tires more times than I can -or care to- count (it's been often enough that I've almost gotten used to it happening as much as I push the limits, it's to the point I keep my right hand on the loader controls in order to be able to react faster should the backend start feeling a little "too light" when dealing with large/heavy loads). However, the smaller trees should be easily handled and could likely be pulled out like over-sized weeds with the grab, push (or pull) and lift technique....
anyway just my :2cents:
