Dutch Openers

ajd132 · May 25, 2015

I am thinking of using The Dutch double slot opener with liquid fert and 5inch seed band on my new sprinter instead of duet coulters which I think are too agressive, smear and germinate Blackgrass.
What experience do people have of these in DD and (proper)minimum tillage?
The nature of what we do means I need something flexible.

We have put seed only Dutch openers on our sprinter for the reasons you mention. We have the 5" for cereals and 1" for spring beans and osr. Both have worked well so far although some issues with high seed rates in beans(see another thread) May look at adding some sort of fert at a later date but am unsure of the benefits at the moment.
These seem easier to pull than duets. and no smearing imo, but 5" are fairly high disturbance.
Overall I am happy they are an improvement on duetts

I fitted 5" coulters to my CO4 to lower the disturbance and to help with seed depth. I am very pleased and the crops look at least as well as the ones drilled with our standard Topdown/Rapid approach. The same coulters are also used on Sumo DTS which we also have. Most of our 1st wheats after osr or beans were established by just a very shallow pass with a Carrier, spray, drill +\- rolls.

Thanks, how low disturbance are they compared to Duetts? ive ordered a set of horsch bean coulters but would rather use the one inch tip but as you say I am worried about high seed rates. I take it you get them all direct from Sumo? From what I work out you need the boot and tip to fit into the Sprinter leg?

I'd be interested how you get on with dutch openers as this is something I would like to put on my sprinter. Any chance of a photo of the openers on the drill. A lower disturbance may be the way forward with the high output of the drill.

ajd132 · May 25, 2015

I am going from an 8m to 12m. I think it will make it a more versatile drill. I need to see some pictures of them on a drill.

Standard 5" double shoot on the left, and the standard 1" single on the right. The middle one is becoming more popular in some cases, it's an open bottom 5" and will handle any size seed at any seed rates. Only slight disadvantage with this one is you don't quite get as wide a seed row as the standard 5 but the low draught and high wear rates are the same. All of these three coulter options are on stock and we are able to provide any of the Dutch range on request, just have a look at their website. http://www.dutchind.com/

Thanks MDA, I have spoken to Pip in you're stores and got some stuff through. What do I need to connect it onto the Horsche leg?

Wheatland · May 25, 2015

I don't know how well these photos will show but the disturbance is fairly low for a tine drill as long as forward speed is limited. The other photo is wheat drilled straight into freshly harvested maize stubble in late October 2014. Photo taken in Feb15

You'll need an edge on adaptor that bolts directly onto the existing leg. Cheers.

What is wear like on them compared to a duett?

Banana Bar · May 26, 2015

I'm liking your thinking, I'm going to be keeping a VERY close eye on you this autumn

So far so good, although we did have one crack but unsure if it was due to a stone or putting drill down on concrete! Never happened with duett though.

Adam I tried one on the edge of my drill this season in spring barley and couldn't get the seed to come out properly. It would either block or not come out uniformly. I was also slight disappointed in it's performance it didn't seem much better than the duett and i dare say when hard you would struggle to get them into the ground direct. I was so please I didn't order any without trying them!

ajd132 · May 27, 2015

We will have open bottomed 5inch so seed flow shouldnt be an issue I don't think? Can definitely see how the banded one has seed flow issues. I agree I don't think its will be hugely different to the duet just less smear but I like being able to quickly change between 5' and 1''. Been told they last a very long time, they should be easier maintinence wise compared to the duett. We used to end up throwing out a lot of the plastic things only part worn as it was easier to overhaul the whole thing in the winter than muck about with a rivet gun etc in the autumn/spring when time is of the essence.

Are you still pleased with the dutch openers ajd? I like the look of Julian's Metcalfe points on his CO.

ajd132 · Mar 13, 2016

Yeh happy with them but it's horses for courses really.
But the Dutch do liquid fert and I think il use the wide points for establishing cover crops into the chicken muck.

Tom H · Mar 13, 2016

Are the liquid Fert pipes on the back easy to damage? Will the block up if not applying fert, duetts do in sticky going. I'm not on abrasive soils but wear okay? No ground penetrating issues?

ajd132 · Mar 13, 2016

I havnt damaged any and they don't seem to block up. Wear is good and no issues with penetration

@adj132 How are you getting on with all of the above after a couple of seasons? Looking to do the same, Cotswold brash being the soil type!! Many thanks.
