Drilling OSR with sabre tines/coulters on a sumo subsoiler

[KB6930]

Presumably moving the packer back would make it harder to lift?

Yeah but not as bad as hanging disc coulters off the back

I think the 3rd hole is roughly 3-4 inches further back

We’ve had to strengthen ours around the packa roller frame as it had started cracking. I would say ours is a trailed version.

1st year sowing osr with our trailed sumo with the seeder kit and sumo coulters fitted

It has 6 coulters on a 3m machine running inline with each leg, 125kg of N spun onto stubble before sowing and the results are pretty good

Do the newer trailed sumo's not have the wheels at the back behind the packer anymore? Our 4.5m 2009 trailed has the wheels behind the packer so don't think it would be possible to fit the drilling coulters to it.
Also got a 3.5m 6leg mounted trio. Thinking we might buy the sumo drilling coulters for it. Looked to have performed well for you @Bobthebuilder. Do you find they have plenty of pressure on them to cut in the ground and not bounce about on top of its dry and hard?

Newer 3m Trios have the mid mounted wheels not sure about anything wider. I'd reckoned looking at the Weaving disc units as although you have to fabricate a frame to mount them they are a hell of a lot cheaper than sumo.

It’s a trailed machine not a machine with a trailing kit (which had wheels at the back) not sure about the wider machines, as for the coulters, disc pressure is ok but we have had an issue with the brackets and bolts that hold them to the frame not being strong enough but sumo are on the case redesigning the brackets

Good to know that sumo are sorting out problems like that. Hopefully we will have chance to look at various rape drilling systems at Lamma.

@woodylane we are in the second year of running the weaving disc coulters behind a 7 leg v form. It’s has transformed our rape establishment and seems to have paid dividend this year in challenging conditions. We also blow 10kg/ha of umostart fertiliser down the pipe which is now placed directly around the seed, another advantage of the coulters! Our only issue is the build quality of the coulters, we drill between 400 and 500 acres a season and the pivot bushes for the main Coulter arm and the press wheel arm just fall to bits resulting in lots of play! And the plastic depth also crack up and fall To bits, do you find the same? We run them behind the packer, slightly offset to the leg (between 10 and 50mm depending on conditions) and have the press wheel set the same as yours. We are on heavy ground so when it comes a bit rough the coulter is working hard to keep in the ground, plus they are cheap enougt but wear still seems excesssive. We changed the angle this year to keel more pressure on the press wheel so the Coulters weren’t bouncing around as much on the rough ground but seemed to make little difference to wear, seemed to help establishment though! Would be interested to know how you’re getting on with them?

So far nothing has fallen to bits but we are only putting 2-300 acres a year through them, I am carrying them slightly on the frame as we have some very light land where i can’t rely on the press wheels to maintain depth so I made it so I could adjust depth on the frame. Heavier ground this is not so much an issue. To be honest after I finished sowing the rape I was flat out discing and spraying so the trio is where I parked it in the shed and I’ll get it washed off soon and asses for wear and tear. Will update when I’ve got her stripped. As far as establishment goes they have been brilliant, before we were dropping the seed on surface after packer and had following tines to cover over, I think we lost a lot to pre emergence sprays especially where clomazone and glyphosate used. Now all seed is buried and emergence very even across fields and soil types.
