You are sure to create problems if you ask him to move it. On the line, or 10 feet back, don't worry about it. Move on, you got 300 acres. If it were over the line I would make him move it. If you are descent to him, maybe when you have to go on his property to retrieve a buck he won't mind. You are leasing and not the property owner anyway, a problem may cause an issue with the owner and put your lease in jeopardy when it's time to renew.
