First off I would like to say, "hi." I found this forum while search google in hopes to find a good mower. I know form prior experience form using forums is that a lot of the same questions get asked over and over and over again so please bare with me. I am looking to purchase a new mower and I would like to ensure that I get a good one that will last and meet my needs. I have been looking at ZTR's at Lowe's and Home Depot. At the time I was thinking about 3 things: 50in deck, commercial grade and ztr. So I talked to a co-worker that has a ztr. The advise he gave me was get a 48in deck because the 50in won't make a big difference and that I would cut my mowing time in half by definitely get a ztr: very tight turning and cut faster. He purchased a commercial grade ztr becuase he has about the type of lawn I have. I do not remember the name band he said he had. So after this talk I thought I would like to hear from people that use them as part of their job. Basically, what mowers would you guys recommend? Background: I have 4 acer's and I mow all of it with a nice low cut. It's relatively flat: bumpy and rocky here and there. I sometimes do let it get a little thick before I mow it again. It takes about around 4 hours to mow it all. By the way, I currently have 2 riding mowers that are constantly breaking down which is the reason why I am looking for a new one. Mowers: Huskee -12hp - 36in deck - age: unknown, was my grandfathers. The desk has been welded back together blade spindles have been replaced starter replaced one time. Desk is falling apart again. Craftsman - 12 HP - 38in deck - Age: 17 years I believe. Constantly replacing starters Constantly replacing belts Constantly replacing blade spindles The deck it's self is in good shape, dent and ding here and there. Thank you for the advise.
