I have been looking into getting an exmark, and have been asking around on ones preferences, Kohler vs. Kawasai. I have been going back and forth between the LazerZ hp, and the LazerZ advantage series. I don't want to get a deck too big because I have quite a few residentials with gates that I would not be able to get through with anything larger than a 52" for sure. For this reason, I have been leaning more towards the HP with the 50" deck. Engine options on that are 23hp Kawasaki, or a 27hp Kohler. I have a 23hp Kohler right now, and although I have not had any problems with it YET, I have heard the surprise some have that it has run fine. I want more than 23hp, but don't know if I should stick with the Kohler. Now, I come to another problem... if I want more than 23hp, and Kohler is not the answer, I have to go for the Advantage Series, with the 28hp Kawasaki. The only problem with that is the 52" deck, I don't have time to be push mowing what I can't fit into on the residentials, so I am nervous to get that big. SO, please let the advice flow... Thanks.
