I don't see how he can legally tell you when you can harvest your crops. If I was the hunter, I would be mad if someone started cutting there crops when they knew we we hunting, but, on the other hand, the land owner should have told the hunter that those crops would be getting cut. You have the first rights to do as you please, not the hunters. Your paying for that right. I would cut, there is nothing the land owner can do about it, legally, unless its in your contract that you can only cut if he lets you... Just my opinion..
