Please for give any spelling mistakes. Have done several spring clean ups all lawns covered with Onions and Dandilions. Problem is I had to go cut them twice to get rid of them. Is this common. Im using a Toro wb Proline 48" fixed deck with gator blades. And yes they are sharpened and balanced and will cut grass like a sharp knife through butter. So do you guys have any advice as this would save me a lot of time. Thanks in advance for any help.
