Patent ID: 8627898

Claim:
A tillage system comprising: a) a tilling unit having a pair of supporting front wheels towed by a tractor drive; b) said tilling unit having a common tool bar carried by said pair of front wheels with three or more tool bar segments for attaching tool frames, the tool bar segments being positioned one behind the other in the direction of movement of said tilling unit; c) said common tool bar having attached thereto a first tool bar segment carrying a first tool frame attached to a first set of a plurality of deep tilling tines producing deep grooves in a tilled field, and being provided with means for adjusting spacing between the tines, means for adjusting the deep tilling tines up and down as a group being loaded by spring force, compressed air pistons or hydraulically actuated rams, and deep tilling tines rotate at a rotational speed matching the ground speed of said tillage system; d) said common tool bar having attached thereto a second tool bar segment carrying a second tool frame attached to a plurality of rows carrying sets of shallow tilling curved coulters) the total number of coulters carried by the sets being more than twice the number of deep tilling tines and being provided with additional means for adjusting said coulters up and down as a group being loaded by spring force, compressed air pistons or hydraulically actuated rams, and shallow tilling coulters rotating at a rotational speed matching the ground speed of said tillage system; e) said second set of shallow tilling coulters being adjustable in orientation with respect to the direction of movement of said tiller; f) said first set of plurality of deep tilling tines comprises inserted hardened steel elements that extend from the surface; and g) said shallow tilling curved coulters on the second tool bar segment displace soil laterally during tilling; h) the common tool bar having a third tool bar segment directly behind the second tool bar segment that carries a row of shallow tilling toothed coulters; and i) a shallow tilling toothed coulter or waffle coulter being provided in front of deep tilling tines in order to size large length tall plant debris prior to deep tilling; whereby the shallow tilling coulters smoothen the tilled soil surface, eliminating mounds formed on the sides of the deep groove generated by the deep tilling tines, and removing plant debris between the deep tilled grooves, creating a clean tilled field appearance, so that shallow tilled regions provide sufficient water absorption for rain Of irrigation water, substantially eliminating water run-off, as well as soil erosion.
