Don't worry, I won't ask what is the best mower. I have been reading here and on two other forums for two days now, but I do need some advice on how much power I need. I have sent out emails to about 15 local dealers and will start visiting them this week. I live in Santa Fe, Tx and have one acre of thick St. Augustine. My current JD LX133, w a 15hp Koehler and 38" deck with mulcher has done a great job, but after 10 years I have decided to get a ZTR. With all the rain we have had, my grass is really growing and this last weekend, I spent 4 1/2 hours cutting my grass three times to get it right. I cannot spend this much time and need a bigger deck and more power to cut my mowing time. I have decided that the smallest motor I would consider is a 19 HP, but will the 19hp pushing a 48-50 inch deck have enough power to cut my grass or would I need to consider a 20 or 25 hp engine. I know you cannot cut as low with a mulcher, but with a deck this size I could easily make two passes in less time than my current mower will cut in one pass. I have enjoyed reading here and have added this site to my other favorite forum reading sites and will visit often.
