This one is 61" and has 6. I keep it maintained so they are in good shape. A deck that wide just wont cut uneven ground as low as you want. I have to cut it higher than Id like if I want it to look good. It doesnt bother me to scalp it back every now and then cause I hate grass and would just spray the whole damn yard if my wife didnt care but wanted the OP to be aware.
