Just wanted to know what is the true benifit to going with a parralink drill??? Yield?? I know that you get better seed placement, but is there any data to prove that a seedhawk give a better yield than a flexi-coil 5000?? or a Bourgault 5810??? I have watch the performance in our area this year and I see guys pulling, Heavy harrows, diamond harrows, and vertical tillage units in front of their parralinks to be able to seed. What ever happened to the whole concept of ZERO tillage?? I just does not make any sence to me, Why would you want to go and buy a unit that forces you to add another operation to the seeding season??
What are your thoughts??
I wouldn't hire me either to seed canola

, given the new conservapak, hawks, masters etc do a better job then a 20 year old design. Changing over to Pillars, so now would you hire me?
Its an extremely valid question, does a paralink, with quantifiable data, YIELD better then a single pivot. Does the bourgault with jacks and hoses and needle bearinged paralink Pillar design yield better then a single plastic bushing lined Pillar Lasers built opener pulled by a spring? Also the question about zero till unanswered, as all the 'activity' and the look of the almost black field on most of these units bring the entire category to direct seeding and absolutely not zero till. Maybe zero till doesn't work as good after all. Its why we are giving up on the Barton, the seed takes too long to come up, ground stays too cold - as long as we have wet cool weather.
Its a fascinating question.
But the original question remains unanswered, is yield better.
