The lower contacting edge is arranged at an angle to the ditching direction. The earth shaping apparatus further has a ditching blade coupled to the earth shaping apparatus in front of the leveling blade with respect to the ditching direction. The ditching blade has a contacting edge extending below the lower contacting edge of the leveling blade when in use.
