The owner of the Evolution says he can't get used to the hand controls. I did not say I am giving up on the zero turn, I'm just not happy with how it responds going down steep hills.I can easily turn around on any hill, it's in the turning to go around something while going down hill , that the problem comes. sometimes it is unavoidable. I appreciate the idea of lower tire pressure and I have done that. Maybe my hills are just too steep. It will however , go up just about any hill. I do not yet know if one can walk behind an Evolution, but my logic tells me that weight added to the back i.e the operator, would help the traction going up or down hill,assuming it dosen't get light in the front. When I try one I hope too have some answers. Thanks for your replys. cop
