The Stihl FS-90R polycut
attachment is in my
opinion a huge improvement compared to using traditional string.
It's easy to replenish the
plastic fingers, but no so forgiving when it comes to getting too close
to chicken wire.
I might be switching back to
string for the chicken pasture perimeter. The swap can be done in less
than a minute once the turning head is locked down by inserting a
screwdriver in the hole on top and recognizing that it's threaded on in
a reverse fashion.
