why is my mower not cutting the grass right?

Yes you can get a new blade - but when you go to the shop you will need to tell them some details about the machine - make - model - size of blade.

If you have what's called a cylinder mower then the story is a bit different.

It is not easy to tell why the mower isn't cutting as it did but the blade is a good place to begin.

Good luck...
