If it is an electric mower the head of the bolt is plastic and will normally come out quite easily with a good ring spanner, if it is petrol it is normally a 9/16 head bolt, a good socket and bar will take it out, if the edges are rounded off you may have to grind the bolt head off to get the bolt out.
