At first I had my eye on the Toro Estate z400 with 48" deck. My dealer said he thought the motor that comes with that model was a little under power since it only has one cylinder( 18hp Kohler) so now I am looking at the Z400 estate with the 52" deck because it has a 19hp Kaw. with two cylinders. Price is $5,699. I keep asking him about the Z400 pro value which I can get with a 48" deck for $6200. But he keeps insisting that is way more mover than need for my 2 1/2 acr. for home use only. I think I agree with him. Like opinions on this model.
