Wedge-Till Row Unit

Wedge-Till Row Unit NO-TILL EQUIPMENT No-Till Equipment 18-5-5 You've heard of ridge-till, no-till, minimum-till, and strip-till. Now there's "wedge-till", a new-style planting method that uses angled disc openers like nothing you've ever seen before. The Australian-built "Vydrill" row units lifts up a wedge of soil and puts seed and fertilizer underneath, then puts the wedge of dirt back without disturbing the soil surface. The angle and spacing of the discs virtually eliminates sidewall compaction, ac-cording to the manufacturer. The spring-loaded discs are spaced about 5 1/2 in. apart at the bottom of the seed trench, creating inclined furrow walls. The momentum of seed carries it down the fur-row walls to the bottom of the trench. Seed and fertilizer can be placed on each side at the bottom of the trench, allowing small grains to be planted in paired rows. Or, by using one tube for seed and the other for fertilizer you can band fertilizer alongside the row. When operated at a depth of 4 in., the discs disturb about a 14-in. wide strip of soil at the surface. By using three ranks of discs you can completely disturb the soil surface for mechanical weed control. A single rank of units can also be mounted on a toolbar and used for strip till-age in heavy residue. Depth control is adjusted by raising or lowering the toolbar or by using a kit consisting of rubber press wheels that mount behind the discs. Contact: FARM SHOW Followup, Terratend Pty.
