Weaving GD user thread

[Case290]

Had some spring barley drilled weaving gd . checked to start with seamed ok but seams a hell of a lot of seed onthe top now . I asked the contractors what’s happened and he said that it’s the drill it always does it. Is that true with all the other gd users or is it drilling speed related.

 

[Farmer Roy]

is that due to lack of penetration, row units bouncing from high speed, or seed being blown out of the seed trench by too much air ?

sounds like a sh!t operator to me . . .
or a badly set up planter . . .

The air exaust on the coulter always lets a few grains out I've always thought they need partially blocking

 

[Farmer Roy]

need to run the D Cup style cyclonic air diffusers that let ALL the air out so the seed just drops down the tube, rather than being blown
all other air brakes or exhausts will always blow a few seeds out, especially light ones.
Still, should at least drop the air pressure back a bit, its not like your trying the push the seed any great distance through the hoses

partially blocking exhausts makes it worse - as youre increasing the back pressure & the speed of the air coming out, through a restricted opening . . .

There's always some on top, blown out the exhausts
Keeping a close eye on fan speed can reduce it a bit, but not a lot

 

[Farmer Roy]

exhausts are only a bit of a half hearted compromise, to be honest . . .
weve got about 40 or more years of air seeder experience over much wider machines . . . we want to place ALL our seed into moisture, in the seed trench, not on top of the ground . . .

One of my osr on my way past today.
Be going through with sclerotinia spray soon so I'll have a better idea of what it's like now.

Looks very good and even

 

[Case290]

Looks a lot

Yes it does is it just one or two rows or the whole width could be blocked coulters causing it all to come out exaust

If you want to work it out you need to know seeds planted /sqm, then have a count up, doubt it will add up to much in reality. think we spend far too much time and money worrying about the odd seed on top tbh, slugs have far more of an effect given the chance.

 

[Case290]

roughly 250sq/m on top planted 450 you just made it worse but good to work it out I guess. Weaving drill or contractor ???

Your soil looks a treat wish ours looked like that

That's bad.
Shouldn't have that much unless the seed was poor and kept blocking the exhaust so blowing it out. (I've had some difficult barley with awns on it still, impossible to stop it blocking, just had to keep getting out and checking)
I'd say fan speed far too high.

Lol . No you don’t . wouldn’t wish it on any one.

Why what's up with it. But more importantly it looks moist

Haven't had the problem here. But I drive max. 9 km/h.

 

[SorenIlsoe]

Drilling spring barley into old ryegrass crop. No seeds on top, but speed at 8 km/h. Maybe that's the reason.

 

[jack6480]

Has anyone used the gd to drill grass seeds yet? Did some the other day on some disced ground had the depth in 3rd from shallowest hole went in ok I hope,field was very rough which was a struggle to get a consistent depth

I'd say that was excessive speed, though the air brakes do leak the odd one. I had an 8m demo travelling at 7 kph due to the very high seed rate. Not one seed on top except where pulling out on the headlands.
