I need a little help from the pro's please. I am a homeowner in North Texas with 5 acres and 3 full acres of irrigated lawn. I have been looking at new and used commercial Z-turns since for about the last 3 months and have a few questions. I am looking at the 2nd level of commercial grade mowers with 50 -52" decks just above estate grade (I have trees in the back). Scag "tiger Cub", Exmark lazer Z ct, Toro 400 series, Ferris, Hustler, and an occasional Bushhog or Gravely. The ones with 7 gage decks, fabricated decks, bigger motors, bigger tires and individual pump and wheel motors. I have steered away from the estate size mowers with the charged hydro gear just because it is not as fast & seems less beefy than individual pump and wheel mowers. Every time I walk into a dealer though and they hear 2 acres of lawn they take me right to the Freeedom Z or the 3oo series Toro. So question 1 is the Pump/wheel motor combination really better than the Hydro gear, or is it that I just won't notice with once a week use. Is the speed, 7 vs 10 mph that important. I said I had been looking at several used mowers and have a general hour limit in mind of about 600 hours max. This usually gets about 1/4 -1/3 off the new price. I figure that if i can get something under that range, it will still last me a lifetime for 1 - 2 times a week duty. Am I correct, or should I just bite the bullet and buy new. Is there any one particular brand that I listed that is not in the same class as the others? On the motor side, most are found with KAW or Kohler with occasional B&S ELS or Intek. The briggs usually are bigger in the same price range. I am thinking 23 hp should be sufficient for a 50 -52 inch cut, but Ivie seen some as low as 20. Any comment. Finally, on deck size & quality of cut. I noticed the pro's like 60's. Any particular reason for a 60 vs 52/50. I have trees, live oaks in the back most I could squeeze through with the biggest issue being getting under low hanging branches which are about 48". Most importantly is quality of cut, does anybody hold the edge. I will probably be mulching and striping during the summer on turf type Bermuda. Is there a particular deck height that improves cut, does anyone have an advantage. I just finished my self designed/ installed sprinklers (16 zone Hunter in front yard only) and my neighbors had a fir when I pulled up with a ditch witch behind my truck. They made me park it in the back overnight. I want to smoke my neighbors that have everything done for them. thanks, Fred C.
