I have about 2 acres to mow at my home and need a new mower. I thinking of a Zero turn mower. I have never been on one, but I want to cut my mowing time down. My question is how do these mowers do on steeper uneven ground. None of my yard is totally flat. I can mow it all safely on my current mower going across the grade, but it spins alot when turning and you are constantly shifting your weight.There are ditches to mow etc. Do these mowers spin like a normal mower. Will they ball-hoot going down steeper grades. Im thinking of a Husqvarna RZ5424.
