Double coil spring Open Close

Double Spring Tine

Double coil spring

Each  disc hub is mounted on an individual heavy duty double coil spring support. The coil support produces a permanent 3D vibration which improves soil refinement and residues incorporation. The spring arm allows an indipendent action of each disc and compensates for varying ground conditions as discs can move upwards and sideways.

Agronomic insight

UFO is designed to accomplish several actions in the field:

  • Residue sizing – Aggressive notched blades slice through crop residue to effectively size it for rapid decomposition.
  • Residue blending – The high-speed rotation of the discs turns the soil while chopping residue. This results in an ideal mixture of tilled soil with properly sized residue.
  • Oxygen introduction/warming – As the soil and residue are mixed, oxygen enters the tilled zone and in cooler soils the action also warms the seed zone for rapid crop rooting and emergence.
  • Activation of soil bacteria – Machinery doesn't break down crop residue as the soil bacteria does. When soil is warmed and oxygen is introduced, soil bacteria becomes active and feeds on crop residue. During this process, the residue decomposes and the nutrients become available for new plantings.
  • Finishing – Consolidating the soil/residue mix helps bacteria break down residue better. The consolidated surface also produces an ideal seedbed, prevents erosion and creates a capillary effect to preserve moisture.

Containing side discs

Easily adjustable side discs (in depth and inclination) allow a perfect soil retention even with heavy crop residues, preparing an optimal seed bed and leaving a nice flat finish (no side ridges or furrows).



Disc diameter and concavity Open Close

Disc diameter and concavity


UFO notched discs have a wide 24" diameter and are 1/3" thick. They are made in high tensile boron steel and have a soil contact which is four times wider than the smaller diameter discs. The discs concavity ensures better soil straw mixing even on a very high density residues, then conventional vertical discs.



Culti-Hub Open Close



UFO include maintenance-free disc hubs with metal face sealing, double bearing and oil-filled, thus providing long service life (20,000 acres warranty). Discs are mounted directly to the bearing caps, which helps shield the bearing from damage in the field.
