Design of the low-till parabolic subsoiler

1994 Beltwide cotton conferences Volume 1 Proceedings of a conference held in San Diego, USA, 5-8 January 1994: 531
Design of the low-till parabolic subsoiler
A low-till parabolic subsoiler was designed, which utilizes a straight, parabolic-shaped shank angled at 28 degrees from the vertical (away from the centre of the subsoiler) to reduce the amount of soil surface disturbance. The angle of the shank allowed it to run in fractured soil while reducing the draught requirements. The leading edge of the shank was cut at a 45 degrees angle to provide a sharp edge to reduce soil lift and draught requirements.
