A couple of days ago I bought the 717 and 757 to add to my fleet. I had asked several 717 owners about their mowers and what they said was all true. The 717 is amazing !! I already had 1 757 I have been unsing well abusing is more like it, we have really put this machine to the test and it has proven to be the best IMO time after time. So I decided to buy another one, there are some difference from my first 757 to the second but I can live with them. The orignal 757 just had the belt replaced for the first time in well over a 125 hrs and that is the only thing I have done. I will keep everyone posted on all 3 units, I would take pics but all of them are already dirty, they were used the first day I got them. I working on getting them !!
