Hello Everyone, this is my first post at this forum. Im in the market to buy two 52¨ ztrs and I have a few questions about the new Lazer zs. It looks like they redesigned the hydro pumps to be hoseless, is this a good thing? What problems might arise from this change? Also, What kind of performance differences are there between the Ultracut 4series and 6series? Lastly Ive got to chose between a 23hp kawasaki , 23hp or 27hp kohler command engine, whats the difference between these engines? I know there is alot of people that think Exmark is way over priced (including myself), But money isnt a factor in this choice.
