Well, I dragged it out, and my lawnmower was just about cutting the grass but taking me forever, so what did I do.

Was really lucky and found a local company to fix it Power Equipment Repairs for lawn mowers in Yorkshire, what a job they done.  I cut my neighbors grass just for fun when it was returned and was so impressed, I even cut my own once more before the session ended.  Lets just hope my grass does not grow too much over the winter, but with these new blades I'm know it wont be an issue.
