Its cool mate, a pic or 2 of the filled in ruts so I can get my head around it. But only if you want!
Yeah mate, wheeled skids are ok if its a new build or in an area thats going to be fixed, re turfed or not bothered about but driving them over existing grass is a bad idea. Seen it many times!
Tracked skids are the way to go and while they usually cost more per hour, "can" also get stuff done quicker with less damage. They are still heavy so sh!t will happen and the grass wont like it but you'll have far less rutting etc to deal with.
Getting a machine to do the heavy work is definitely the way to go but just understand there limitations! I wouldnt let this put you off in future. Just learn from it, sort it out and move on.
