I'm looking to buy a 2007 HP with a 46" deck. I am having trouble deciding on which motor to get, the 19HP Kawasaki or step up to the 23HP Kawasaki. There is an almost $900 difference between the 2. The dealer said the 19 would be fine but I might not be able to mow flat out with it ( I doubt I do that anyway with the shape of my yard). I'll be mowing about 2 to 2 1/2 acres, all relatively flat. Help me decide guys. I'm glad I found this site!!
