If you are gripping the digger with your right hand you put the palm of your left hand on the guard and apply pressure with your left hand going to your right. You develop more force pushing motion than a pulling motion. In this manner you are using the force of both hands. If the serrations are on the left you are applying very little force with the left hand as you cut across the root.Originally Posted by MartinL link=topic=5553.msg66900#msg66900 date=1304079681
Hard to explain a video would be helpful. Contact Predator tools and ask them why they make the Right Hand Model the way they do, perhaps they can explain better than I did.
