How to make terraces using a walk-behind tractor and a rotary plow?

From internet research I have come to think that a rotary plow on a old gravely walk behind tractor is the cheapest/best solution for me in regards to terracing off the hill side my land is made from - it is one single slope (with one large terraced spot in the middle of the property that a mobile home once sat on).  The water races down the hill and continually ruts and destroys my gravel driveway.

I want to terrace the upper half of my 5 acres and plant growies - to include fruit trees

My Question is:
How do you actually use a rotary plow to make a terrace - 5 feet wide on a slope of more than 20 degrees but less than 45.
