So I bought a brand new Pony ES. I have had a front tine tiller for 25 yrs and bought a new Pony. I have never used a rear tine tiller. So today I attempted to....When I pull the handle to engage to forward motion, the tiller accelerates to a running speed and jumps out of my hands. What am I doing wrong???? I feel very dumb, but I have read the booklets 3 times and it says nothing about a governor or way to start off slowly....any input is greatly appreciated!!!
