Mr. Brewster
In my experience it is not so much the lack of power,
which with a 25 or 30 cc engine and a 10" or 12" bar is usually more or just
slightly less proportionate to larger saws, as that, unless working from
above or to the side with a MEWP, it is very difficult to place your cuts at
the correct angles, especially for the first two. So the branch twists
instead of hingeing. That is what leads to the saw getting jammed in the
cut, not the lack of power. The stub cut-off is usually easier, but it is
also more likely, because of the difficulty of precise control at that
distance, that the tree will be wounded when making the final 'clean' target
cut. That is if you haven't been whacked by the lump sliding down the pole
instead of falling straight....
I have to say that I do prefer them for work from a MEWP as I really do
not like working with a saw that close to the metal cage, especially
starting it up. The advantage of all "long-arm" machines, and even more so
with hedgecutters, is that the moving parts and cutting edges are well away
from the operator.
