I have just put a new deck on my Twin Cut TC102 (like castle garden) and when i reasembled it, it is not mowing properly. It is leaving a gap in the middle, the grass left is being hit but not being cut properly. I did sharpen the blades before reassembly but am not sure if I done it properly. Does any one have any ideas as to what i can do.

The blades are handed and are on the wrong sides.You are hitting the grass with the backs of the blades.

Is it perhaps the tension on the deck drive belt?
