One possible exception is the Paratill Plow, which has been studied at several locations in Central and South Texas. This deep-tillage tool is equipped with coulters that slice through tight sod and plant residues. Improve internal drainage through the destruction of clay pans or compacted zones. Bigham Bros. Paratill plow illustrates pairs of legs facing in opposite directions on the tool bar.
Fluted coulters slice the sod ahead of each plow leg.
Gauge wheels provide assistance in determining depth of tillage. Bury surface residues important in protecting the soil. Create clods and roughness. Require additional trips for selected operations. The Paratill Plow leaves a smoother soil surface than a chisel plow, parabolic subsoiler, or V-ripper.
