If I had ruts in my back, I would avoid laying down in front of what ever left them there. /w3tcompact/icons/laugh.gif
On the serious side. If a rut is lower than the surrounding area and you were to use say a 5' box, you would then have 5' ruts. If the ruts were actually higher than the surrounding area, the box could and would help displace the high spots and fill any low spots. But then you would have started with a ridge.
If indead these are ruts, then it is a good place to hide all broken tractor parts in before filling. That is if and only it is not to be a finished lawn. With my luck, that's when the in-laws would show up with a metal detector and think they've discovered something significant and want to give me my low spots back. I'm in a rut just thinking about it.
If the original ruts are from tire traffic and it will remain a traffic area, throw on some more rocks. /w3tcompact/icons/laugh.gif
Stick around. You will get a lot of information at the best little tractor site in the world.
