Circa 80-90k has been quoted to me recently. I'd concur with the 85k figure
Any problems with seed depth? Saw a demo of the GD that worked well but some seed ended up being placed too deep and it never made it to the surface. Seed could be seen on the side of the slot that grew well, but also well under the flap of soil. This was to deep for it to emearge.
Seed placement is the drills biggest weak point in my opinion. I've had more trouble with seed too deep than anything else. You have to accept a bit in shallow/on top, and stop with the drill in the ground to find the true drilling depth. If you have a lot of pressure on the closing wheels the deep seed runs out of energy to break through, especially in a dry time like this when the top bakes out like a concrete ceiling!
Nothing has failed to come through from being sown too deep here so far....................
I think I've said elsewhere in this thread that I tend to have to drill about half an inch deeper than I used to do with my old drill. This can at times be a benefit when drilling in trash, sometimes before I didn't always cut through any thicker piles and left the seed on the surface. That problem is much improved now.
@Cutlerstom do you find there are enough depth settings on the drill? I am usually happy but have made up a set of tubes that will go over the depth pin, so effectively giving me a half setting in between. I have used them to drill some oats a couple of days ago.
I too have not found anything to deep, but I don't roll much as I find it doesn't need it or am worried of sealing it in
I hadn't really thought about the depth settings. But now you mention it, that's a good idea with the tubes. Could be handy for depth sensitive crops like the winter linseed I put in too deep and looks shite. As you said, cutting through the trash is imperative, but for the linseed it was too deep!
are you getting seed too shallow because you are going too fast.
I find with the Big Disc that going too fast with large seed like beans, they can be flicked up by the disc and end up too shallow. slowing down solves the problem.
I would imagine that the angled disc makes the problem greater as the seed will drop onto it, rather than a straight one, where it drops between them.
You could well be right. I tend to drill at 10kph, but have found it better at 8. Always in a hurry!
I think that was my point. Is there a possible seed placement issue? The seed can land anywhere between the two discs and not at a precise dept below the surface?
Also how does the opener preform crossing a hill/bank. Can the slots turn into a wedge of open soil?
If you are going slowly the seed has time to slide to the bottom of the slot which should be consistent. If the disc is going fast it could flick the seed behind the disc and end up somewhere above the bottom of the slot.
Going slow is a bit of a pain though I would have thought
Anyone else getting through bearings on the big disc on the gd. I must have got through at least 40, weaving tell me that no one else is, so I am not sure if it's the stone content of my soil or what.
I remember asking Weaving whether they'd had problems with their rakes breaking tines, or whether it was just me. They said no-one else was, but I have spoken to others since who have had the same problems.
I wonder if running it an angle has an effect on the bearings - must be horizontal and vertical pressure against them?
Surely only a CS is relatively immune from that?
The problem is related to the limited age of the concept.
Not done any bearings in ours but punctured a couple of tires
How many acres have you done?? I was relatively impressed with the demo and was going to ask users about running costs. You have just put me off!!
2500 acres, to be fair discs are hardly worn and the bearings are hopefully being sorted, other than that there has been no other costs
Will, what are they doing about the bearings? Was it a dodgy batch or are they using stronger ones?
They are investigating at the moment! To be fair they have sent me new ones and have been waiting for me to send the old ones back (which I did yesterday) so we will see
