This subject may be getting worn out but here goes. I am looking at the 2003 models of Lazers. Specifically, the 52" deck. I am undecided between the HP w/23 Koh. or the full size Z w/27 Koh. Both feel and handle great. I have mostly residential properties 1/4 & 1/2 acre. I do have some slopes,(canal banks), and tight planter areas, however, I've managed them alright with my current mower which is the full size Z, 52". I know the deck depth on the HP is 1" less than the Z. Don't know if it mulches any different. If all things are equal, guess going to more power makes sense. Any opinions.
