Papasmith,
I have to disagree with your assertion, that cutting from left to right will not kickback. It is just a logical thing for the blade to try and push out , cutting into a tree from that direction. I believe that all gear head brush cutters turn counter clockwise looking down at the blade. It is only logical to
cut from right to left, because the teeth on the blade will pull the blade into the tree. Some of the brush cutters have a tree stop to help hold the cutter stable, and it is on the left. I also use the 12 in blade with carbide teeth.
I would like to know how you
cut both ways equally.
