Claydon SR - max seed rate for spring beans

[Feldspar]

With the latest PGRO advice for spring bean populations (50-55 established plants IIRC) the seed rate is going to be pretty high.

Normally we drill Wizards at around 180 kg/ha, and even then we were told by Sulky that 9kph was too fast. On another thread someone had calculated a rough seed rate approaching or even exceeding 300 kg/ha.

What I would like to know is whether this kind of seed rate is actually going to be possible through the SR's Sulky metering mechanism without going at some ridiculously slow forward speed?

My plan was to drill the beans with the Claydon and the spring barley / wheat with the Mzuri because of the fert placement. May have to scrub that plan though.

When i had an SR, i got another set of seed pipes and had them running off another set of metering wheels (so there are 18 running on a 3m), and then 'T'ed these using Y pieces into the seed boot, all bits are available from Claydons, only took about half a day to do

...and you'll want a set of these black anti blockage fittings

Thanks. Will look into this.

Brilliant. Thank you very much indeed.

I assume this works on a 3.45m too?

 

[Rob Holmes]

I'm assuming there a 11 coulters on a 3.45m so you'll need 11 free metering rollers, IIRC there are 24 altogether so you should be ok

 

[Rob Holmes]

Just make sure you pair up the tramlining metering rollers (there should be 2 for each side)

We have rigged up an old front hopper to blow fert in with the seed on a claydon, teed the pipes in just above the boot, will we need something to let out excess air? Like those black bits you have, did they cme from claydon?

 

[Rob Holmes]

@Colin, yes they did, but i think they are made by Sulky

Have been drilling beans at 250 plus kgs/ha for a long time, PGRO a bit slow of the mark I reckon @Feldspar ? The power of unqualified farmer observation vs the constraints and cost of replicated trials and academia !

Anyway we used to drill those seed rates with a sr just at slower forward speeds until
We fitted the Y pipes that @Rob Holmes has describe

 

[DaveM]

What speed do you travel at now, with the extra pipes?
Just wondering as I'm thinking that you still have to get the beans through the last 6" of pipe and boot.

 

[Rob Holmes]

Its the seed tubes that tend to block as theyre running at a shallower angle, when it gets to the Y piece the angle is steeper and if your using the short seed boot, the opening is bigger too

 

[Colin]

Ordered the blockage bits just in case but they think I might not need them and could send them back.

I had problems getting a high rate of w wheat in autumn 2012 so first changed the gear on the seed metering chain drive to speed it up, but this was not effective enough, so tried the two tubes into one but that created too much back pressure with seed blowing back out at the metering trough even with the air turned down low!
Now I have altered the drawer guides to put two feed rollers into one pipe, therefore halving the opening on the calibration making the rollers run much smoother at half the speed!

So the speed (conditions permitting) ... 8-9 Km/hr??

Good idea that! My old SR used to drive me nuts as we struggled to get the high seed rates.

TBH, it was not my idea, it was suggested to me on one of the claydon open days last year by another user, consequently this mod was my first job the next morning, best thing I did, as easier on the drill with loads of scope for high rates if needed without any clutter or problems!

That makes a lot of sense, we tried the 2 pipe thing and just got problems with back pressure and drill pipes that resembled toilet u bends!
