I am buying a new wb tomorrow and was wanting some opinions on these three mowers. all three are hydro mowers all are 48 inch with floating decks the mowers are a john deere walk behind with a 17 hp kawi, a snapper with a vangaaurd b & S and a gravely with a 17 hp kawi. I know the smaller 21 inch snappers are good mowers. and the snapper dealer is also the same dealer I use for my stihl equipment He very nice and more than willing to work with us. the John Deere also has decent dealer support as well as the gravely. I am not looking at the others because of the fact that I will ahve to drive over 3 hours to the dealer. so any suggestions or observations will be great. I will be cutting both residential and commercial with this mower I have 69 accounts with the largest being a K Mart that has 3 acres. The reason I am looking at the wb is that I have 8 lawns with insane slopes like 35-45 degree and one of them has a 7 foot retaining wall at the bottom of a 40 degree slope. I have been planning on a new wb to help with these lawns but saturday my ztr burned up the ignition module at 1300 pluss hours on a estate mower with integrated pumps. I just believe it is time to retire it and I need a mower that will cover both the wb and ztr mowing.
