Claim Text:
1. An add-on tillage system comprising: a) a tilling unit having a common tool bar having attached thereto a first set of a plurality of tilling tines or coulters adapted to produce deep grooves in a tilled field; b) means for adjusting spacing between the tines or coulters; c) means for adjusting the tilling tines or coulters up and down as a group being loaded by spring force, compressed air pistons or hydraulically actuated rams; d) said common tool bar having a first mount adapted to receive a tongue with hydraulic mount for mounting to a tractor or power generating agricultural device; e) said common tool bar having a second mount adapted for mounting to an agricultural device adapted to be pulled by said tractor or power generating agricultural device; f) said first set of tilling tines being deep tilling tines and said common tool bar comprising 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 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, and said shallow tilling curved coulters on the second tool bar segment being adapted to displace soil laterally during tilling; whereby the add-on tillage system provides tilling ability to said agricultural device so that said add-on tillage system tills surface soil for a clean tilled field appearance, providing sufficient water absorption for rain or irrigation water, substantially eliminating water run-off, as well as soil erosion.
