Factory default

I bought a Ryobi 125CC petrol lawnmower, last year the 29/09/2023. This lawnmower is excellent, but I have a problem it's seems that there is a factory problem as I cannot give there blade for this lawnmower, I was told at Game Bethlehem they don't stock it, the one sales person told me that I might have to buy another lawnmower, I first felt sick, now I realise that the lawnmower has a 2 year warranty. So I am going to return the lawnmower as it is a factory default. I await your reply. I give your company 48 hours from this review.
