Eastern VA. No such thing as too many Magnums. | We have them on our corn planter. They cut a little deeper than I had figured, but it's fine for corn. It cleans out the bottom of the trench in our sand. We had to take them off for broccoli, but we ended up setting up a new Monosem for broccoli. I also put ours on with bolts rather than the roll pins. Actually seems like we had to use one bolt and one roll pin on ours. I don't know if you can get them for XP units. |
