I'm in the market for a new riding mower this year. I'm looking at the Exmark 60" Lazer with a 25 hp Kohler. I have a few questions. Which engine is better? The Kohler or the Kawasaki? My dealer sells Exmarks and Scags. I'm also looking at the Scag Turf Tiger. I also have a Scag SSZ. You must look at your competition. Why should I buy an Exmark over a Scag? Service would be equal, engines are the same. Scags have drive shafts. What is the warranty on the Exmark deck? As I look at the two machines they seem equal. Small details coud sway me either way.
