The farming operation here is very mobile, so we don't really have any pix of the set-up........it's very "fluid" and changes with each day's interests.  But one thing I would suggest on your set-up:   Either add to the sheet of plywood or remove some of the astroturf and swap it out with a cheap high-pile bathroom throw rug of the color of choice.  The plush bathroom rugs "farm" much better than anything else, as they allow the equipment to leave tracks and rows.  We resurected the old green planter of our boys' from 30+ years ago, and that old bathroom rug has the straightest rows you've ever seen.  Tillage implements then smooth it all out so it can be replanted.   Or, so does a brother's hand when the competition is on strong!  :~)
