Looking for a lawnmower doctor!! When I use my tandem lawnmower I use a heavy duty extension. The mower kept blowing the fuse on the extension. So I took it to Mowpower who said my extension needs a 20 amp fuse (have never had to have this before) and they put new capacitor on lawnmower at same time. Works fine for a while and then we go through this all again. In a year I am now on my 3rd capacitor. I think there must be something else wrong because surely a capacitor should last longer than this and why do I need a 20 amp fuse which I never did before. Are there any other agents other than Mowpower around? Or just someone honest who can help me.
