We plant in 30" rows, you are talking of bush hogging part of the corn, I would have to think about that, deer like standing corn, they eat it off the stalk and standing corn gives them a sense of security, of hiding , if you do knock down some of the corn I would go over and pick some by hand for feeding later in the winter, store it for later use. Check with local farmers for planting dates in your area.If you dont have the equip. to plant with hire a local farmer,, also deer like alfalfa , try plaanting some turnips in the late summer...
