So I have a 2014 gravely zt xl 48. Ever since I bought it, it has been missing grass. But I figured the grass was layer down by the tires and didn't have time to come back up and cut. So I would just go back over it and cut it twice. I took it to my dealer today and they put new blades on it and they tested it out and still did the same thing. It's still under warranty and I have to drop it off tomorrow so they can look more into it. Is this a chance for me to get the upgrade to the hd model? Lol. Do you think they wld give me a discount atleast
