Anyone know of any walk-behinds that you can operate with one hand? Gravely is one, I use a 48" now. I thought it was very weird and touchy at first but when you learn to use the other hand to hold onto the mower you feel much more secure on rough terrain and the mower it a lot easier to get up on curbs since you can push down on the handle with your other hand. I used Snapper before and thought it was the way to go, but after this Gravely experience I think it would be very hard to get back to using two hands to operate one. Any others out there?
