We plant at a 5 degree angle to what we would normally plant corn and then spray everything and combine everything at a 5 degree angle.  We are on 20" beans and 30" corn and it saves a lot of time planting them on an angle and being able to cut them with no point rows.  We decided to do this because is hard to stay off the beans with the sprayer on the narrow rows and have heard there is less damage if you go at an angle for spraying.  I like the way it feeds a lot better and with auto track I can keep an eye on the head and not have to worry about keeping it full.  635F here on a 9660sts.
