G'day Glenn,

Coulters are only really necessary when you have pasture as they minimise
the amount of disturbance to the sod. I use the fluted coulters as well as
these minimise glazing unlike flat coulters. Using the shanks without
coulters results in some tearing of the sod. As you can see from the video
from Spain the coulters do also act to increase the tilth ahead of the shank
resulting in a better soil condition for the sowing of seed with either a
seed box or some of Yeomans Shank Pot Seeders...

As I often say to students and clients, P.A. Yeomans himself developed his
soil building processes (from 1952 to 1973) using a Graham Hoeme chisel plow
not the rigid shank , smooth cutting device we have today (which was
released in 1974 as the Bunyip Slipper Imp with Shakaerator). You can see
the use and outcome of a chisel plow in this
video<http://vimeo.com/13323213>which we put online last year (thanks
to Geoff Booth and Phil Gall). The
most important thing therefore is the pattern of cultivation that Yeomans
developed and the follow-up with timely grazing or flail mulching/blade
mowing right at the boot stage (just before flowering). Certainly the chisel
plow creates a lot of surface disturbance and is more progressive in harder
conditions, whereas the rigid shanks cut to the chase and rip right through
compacted layers right away...

Some useful YouTube links are as follows where the Keyline Plow is featured
are as follows:

And no I don't receive any kickbacks from the Yeomans Plow Company, I am
just an admiring and dedicated user of their products (where appropriate)
and the indeed the whole Keyline Design system defined by P.A. Yeomans.

I put the link up for Royal Purdy on my first response in reply to this
thread but in case anybody missed it: http://www.ahtuttle.com/
