I'm trying to decide between the Lazer, and Lazer HP (23, 52). If I went with the Lazer I would probably go with the 60 deck. However, I only have 3 acres to mow, and don't know if I can justify the 60. Is the 52 Lazer a better mower than the HP? - What are some comparisons between the two? Ride, cutting performance, scalping, manuverability, etc.? - What is the difference between the UltraCut deck on the Z, and the TriVantage deck on the Z HP? - Can the 23 Kohler adequately run the 60? - Engine preferences? Thanks.
