Heh, funny story.
So, my grandmother became unable to mow her lawn using traditional methods. She decided to buy a riding one, but had no idea what to look for. Some kind individual at Home Depo sold her a peice of crap that would just work. I had no idea that this was going down until it was over...
That thing would roll over on you (litterally) after a small bump on a slope. And that sucker was heavy. Changing gears, blade speed (rarly needed), and height was a nearly impossible task. The height was the ultimate problem because you had to adjust each wheel at a time the same way that you would a push mower, only this thing was several hundred pounds. Just to cut a freaken lawn.
I mentioned the gears only because that was a nightmare of a different type. You press the break, change to a higher speed, and this thing tried to throw you off. It would rocket forward, and then slow down to the speed that you wanted it to go. Not a good thing if you where my grandmother, and I found her outside numorious times unable to get the stupid thing off of her.
She wouldnt scrap it, but after a few trys, I wouldnt use it and did not let her use it. So, I just mowed her lawn. She never told us that she needed any help. She was just that type of person.
EDIT: Forgot to tell you guys one last fact. No gas pettle. Just a break. If you started it up whilst forgetting to push the break, it would lurch forward. The good news was, its designers clearly knew the dangers of it as they designed an auto cutoff into the seat. If you lifted your body up in any direction, it would shut off. Normally that would be a bad thing, but I was glad for it when I would find her underneath it and have to pull the thing off of her. Had it still been running, that would have been a near impossible task.
