My dad needs a new lawnmower and now that spring is here, I will need to get him one as I have put it off for months. He decided to try and fix his old one and took it apart. Then he got ill and can't put it back together! We decided it was best to get a new one, but I have never bought one, and could do with some pointers while I am looking. It's not a huge lawn, about 12 x12 and the front a little smaller, so it doesn't take me long to do, but the grass is getting longer now. Any tips would be appreciated.
