I have a few Customer's that have 797's with them, and, if you are mowing flat ground, they are great. If, however, you have contoured surfaces you can have some scalping problems (like any solid Deck Machine)-I have a Customer who is trying to sell one (she had a contract to mow a Football field and lost it, she then went to a smaller Deck for her Residential Customers)-if you are interested, PM me and I can give you her Phone #-
