I note that most of you guys use the low range for speed. Except for one hilly area that I mow in a side hill direction, I never take mine out of high speed. I did have one scary moment when shifting back from low to high speed....somehow the lever stopped in between the two ranges and the mower took off and I couldn't stop it and it was moving very fast...faster than in either range and none of the pedals worked. I shut it off and figured out what I had done. Not the mower's fault...but be careful that you go all the way into the slot for the speed you plan to use. Great machine.
