My 777 has been leaving a terrible cut. I have leveled the deck, checked tire pressure, replaced deck belt, etc. Basically, everything you could do in order to change the quality of cut. I call the dealer and tell him what's going on. He tells me to bring it in and he will handle the rest. I get there and he's got three other salesmen and the head mechanic waiting for me. I explain the problem and they were all puzzled as to how my cut was poor. They take the mower and bring me the 72in. 997 to use while this is being fixed. Best salesmen/dealer ever. Hope everyone else gets this kind of support.
