I have all my fields saved in the ez 500, and works great but i wonder if you need to complete the headland before you can see the AB line. I mean, this year its muddy in some places in the field and i wont be able to reach the saved Headland line. So can i skip over that part of headland and still be able to get the AB line? I could record a new Headland line but i need ro fertilize so would be nice to use the already saved line. Sorry for my bad english.
