As others have said, not enough weight. New smooth blades like on a 330 will be dull in less than 1000 acres. At that point it probably won't penetrate the ground. We re-bladed our 330 with barracuda blades a couple years ago. They don't stay sharp either. I've had a 330 True Turbo for 15 years or so, Would not buy another one. I would sell your disk and buy a Landoll.
