1. In a tillage device having a. an upright shank b. a soil loosening implement on the bottom of the shank, c. draft means attached to the shank for drawing it along the soil to be cultivated, d. an attachment plate connected to the shank, e. a base plate, and f. a horizontal bolt hinging the base plate to the attachment plate; g. the improved supplement comprising in combination: h. said attachment is connected to said shank by elevating means for adjusting the height of said bolt relative to the shank, j. a pair of wings i. each of which is made of a bar of material, each bar of material being oriented so it extends upward vertically at least as great a distance as it is measured horizontally, contd: ii. said wings attached to the base plate to extend rearwardly and backward from iii. a point immediately behind a soil loosening implement, k. so that the wings are free to float up and down about an axis defined by said bolt to fit the irregularities of the soil being cultivated, m. said base plate is horizontally oriented, n. angle means on the base plate for adjusting the angle at which the wings extend rearwardly and outwardly, o. said wings mounted on one face of said base plate, p. said base plate approximately aligned with said bolt q. so the base plate may be reversed, thus causing each of said wings to be above or below said bolt and, thus, higher or lower in relationship to the soil, r. a chain loop mounted on the rear of said base plate, and s. a chain extending from said loop to said upright shank t. so that if the shank is raised, the wings will be raised therewith.
