Interested in buying this unit. Mostly residential accounts, not to be used as a collection unit. Could put a mulch kit on in the fall, not sure if we will. Could anyone who owns one or knows about this mower please answer a few questions: 1) Is the 19hp Kawasaki strong enough for this deck size (46 inch Triton)? 2) Overall performance of machine (turfing, stripping, actual mowing speed)? 3) Would you recommend buying this mower? * The 23hp motor is going to cost me about $1600.00 more right now with the promotions on the 19hp unit, so I am going to buy the 19 most likely to cut on cost. Thanks for the help.
