So true, they have a mind of there own on side hills, I ordered ATV steer tires and put on mine the first day.
Funny story, I was mowing the steep up-hill from the out-house on my wife's farm, my son about 10 years old was sitting on the picnic table about 50 ft from me.
I stalled the mower out going up hill from the out-house, zero turns have no brakes or steering with the engine not running, so back down straight towards the out-house I go, thank god the mower stopped right in front of the door.
My son is laughing his *** off, thought it was funny dad almost ended up in the out-house.
