Never broken one yet but without the leading tine the A shares will work harder[/QUOT

Not far a way from me friend of me bought 6m claydon this spring. In setting tillage leg on shalowest position, drilling leg got too much pool on Stones and had been broken or comes unreliable due to broken geometry ..

I've already got a set of discs with this in mind. The row spacing is pretty wide at 33cm so for band sowing I'd still need a wide A share behind it whch is still a lot of soil movement. I grow a lot of spring cereals and would prefer narrower rows.
What about your claydon with the twin tine kit and twin discs on the front for low disturbance?

That would be better for narrower row spacing. Claydon are supposed to be making stronger rear tines for the twin tine kit but I've yet to see them. I have lots of slopes that mean the tines will not run behind the discs when crossing them so they will have to be strong.

Not hard to get tine to run in line with disc across slopes.
On the virkar the axle steers to keep machine running straight.
Or you could simply fit one or two hill side discs to any machine.

Virkar working speed 8-11 kmh direct depending on ground conditions.
10-15 kmh on cultivated seed beds.

Is a drill that has the ability to have interchangeable disc and tine sowing
Elements of interest. So in effect to drills for the of price of about 1.25 machines.
Taking approx 1/2 day to change over.
Just an idea we have.

Its a nice idea to have interchangeable but 1/2 day sounds a total pain in the backside.

Ability to swap between tynes & discs has been a common feature here for years.
Generally involved just pulling one pin, dropping the tyne out & replacing it with the disc assembly.
Tynes are generally used if sowing deep, chasing moisture - "moisture seeking", sometimes going as deep as 150 - 200 mm . . . In these cases you want soil throw out of the trench so the seed still only has 20 - 50 mm of soil over it. Obviously need wider row spacings for this. 333 mm pretty standard here, but 375 or more is common in areas where they regularly moisture seek
Discs obviously give best placement & minimum disturbance, but are limited in their depth & penetration.

I take it that the use of a front cutting disc is helping to minimise disturbance by the following sowing tine, hence allowing greater forward speed than some other makes?
How do the rear rubber pinch wheels perform in these wet conditions?

Yes the front turbo disc does help to reduce disturbance, the press wheels have been working good in the wet.
We were running one rubber and one steel wheel per element when working in un touched stubble. Last week it was
Working on ground that had been cultivated before the rain came so was like a sponge so we ran two rubber press wheels per element. It certainly showed the drills capabilities in the wet this autumn

Thanks, looks to be fairly low disturbance in the pic.
What soil types are you?
 
Can't say about which drill does what but basic physics tells that with an upright flat disc as speed increases weight must be inceased to keep the same depth as they will tend to rise out of work so you will run out of depth in hard conditions quite quickly. You can increase the weight but then need more HP.
A spring tine will dig itself in until soil bends the tine backwards and a forward facing rigid tine will dig itself in until the tractor stalls or something breaks.

So you can run a lighter rigid tine drill faster than the others but soil throw can be a problem. This is why everyones favourite drill the Tryiton can be fairly light compared to a disc drill.

Can you run with the press wheels removed if v wet?

Hello. At what cost is the green opener available?

That was an Excel row unit, can’t find prices on them.
Here is another locally built one, very similar, I’m assuming a similar price.
It is pretty much what I expected.
That is price per a single row unit

there is a selection of different row units & prices in the following link

Uhhh ... 25cm row spacing, for 3m drill ... 12 rows. It costs as much as this Ukrainian miracle :) https://www.siva-agro.com/en/kharak...-nova-3-0-no-till-technology/siva-nova-3.html

Satisfy my inner geek please folks!

Next year I plan to greatly reduce the use of my Claydon's leading tines & some kind of no till drill will be bought. I've had a demo of a Weaving GD which is what prompted me to ask this question. It seems to be best at less than 9 kph which would mean the difference between a 6m and an 8m here for my workload of around 3,000 acres/year including cover crops. That could influence the choice of tractor size to pull it too, though drill weight and coulter type will also have an effect. The whole disc vs tine thing is a separate debate but experiences of the power requirement for each on lightish stony land but steep slopes would be helpful. Assume a 6m machine with more than 1 hopper.

What is the fastest speed for these drills to work without compromising seed placement?

Any others

The Horsch machines seem to be the favourite so far.

Sprinter with Vos is ok at 14km/h so far. Moist soils though so it’s not like baked clay. Put a cover in (failed mind you!) in early September before the rain at 12km on clay and it went well.
