You need a tail water ditcher, it moves the soil to one side only. And I would like to say Yonkers & Johnson inc. Builds the best ditch plow your money can buy. Check out page 158 in

http://www.californiatractors.com/store/p227/Single_Wing_Ditch_Plow.html At 60 miles per hour, divided via 6.2 miles per gallon.
A truck would use 9.67 gallons per hour. Divide 9.67 via 2 i get 4.83 gallons per half hour, at $2.40 a gallon it would cost $11.59 per half hour to run the engine. At 4 gallons for 4 hours of work, at $2.40 per gallon it would cost $9.60 for a half mile bank. With a plow i could do a half mile bank in a half hour and move on to the next job. At $9.60 divided 4 equals $2.40 divided via 2 equals $1.20 for fuel for a half hour job. If farmer John thought it was cheaper to put banks and ditches in with a crawler with a blade they would not buy ditch plows. Right.
