my mountfield"tuffcut",briggs&stratton quantum xte 55 won't start,the pull rope won' turn the engine over,engine seems seized,about an hour prior to that whilst working,engine was throwing out a lot of light blue smoke,but no abnormal noises coming from the engine.Tried for several hours but still the pull rope won't turn the engine hence failing to start.Would be very grateful if any kind person could advise me in this matter.Thanks

I think you have to determine whether or not the engine has locked up first....remove the plug cap, tie back the engine go lever on the handlebar, tip the machine backwards towards the handlebar. Grasp the cutting blade underneath with a rag, and see if you can spin it. I do suspect your engine will be terminally damaged though - don't like the sound of all that smoke!
