I second the recommendation of the Toro "Personal Pace" by Elevatorman. I've owned 2 and they worked great. They go at the speed of your pace and freewheel when you back up. They are rear wheel drive. They come with a steel or a cast aluminum deck. I prefer the cast aluminum. The 6.5 HP Techumsa engine is GTS. (guaranteed to start). It's a rear ****** or can be used as a mulcher also. It was a pleasure to use! (almost)
