I'm stuck with the slope I have, because the dam is pretty close to the fence line. It is about 3 to 1 in the steepest part.

Has anyone tried either of the zero-turn mowers with the steering wheels? They are supposed to perform better on slopes (even mowing across the slope), because the front wheels are not on casters, and will not tend to turn down the hill. I did a parking lot test of the Cub, and it worked pretty well. The only two down sides I observed were that the steering is a little hard to turn, and the deck can be set in only up or down positions unless you stop and reset a pin for a different height adjustment. As for the Gismow, the dealer is fifty miles away, and he doesn't stock them anyway. But it sure looked neat in the promo videos (at a cost about 100$ more than the Cub. The two WEB sites are Cub: http://tinyurl.com/27fbugn and Gismo: http://www.gizmow.com/home.htm. The Gizmow video sure makes it look almost fun. http://www.gizmow.com/video.htm
