Weaving GD user thread

The drill box unlock was marginally cheaper than Trimble.
You need to find out where the JD sends it's GPS speed output and get a cable to attach it to the drill box, which I bought one Trimble cable for a fortune only to find it comes out a different plug , which cost a couple quid off Amazon.
Then tell the drill box to take it's speed from JD instead of its own.

Might be being thick here , but why is speed reverent, if I want the drill to change the rate by a conductivity map the speed stays the same but the seed rate changes up or down that is what I am trying to do .

Without speed input, the drill doesn't know how fast you're going, therefore it doesn't know how many hectares per hour you're planting, therefore it doesn't know how fast to turn the metering unit.
The vary seed rate just adds an extra variable into the mix.

 

[Steve@mildal]

Understand that , but what tells the metering unit to increase the rate from say 200kg ha to 300kg ha @10kph once the drill is calibrated the rate stay the same regardless of speed assuming its within tolerance, which is what I do now , I need to sow different rates in the same field at the same speed, which I cannot do now. Sorry if I am being dim here . Regards

 

[Badshot]

The vary rate file has to be created , for instance using the soyl website if you subscribe, that gets uploaded to either the tractor box, or drill box, that is then the rates the drill applies depending on position in the field.
The drill will do speed only, for position you need the tractor input.

So a map basically has 200 or 300 areas and the drill will alter the electronic metering system accordingly.
It will do that at whatever speed you are going at, drills using electronic metering do not apply at a set rate of application, per minute, it alters it dependant on speed, either got from radar or GPS.

Not sure how else to describe it tbh.

You have to have tractor GPS position input to do vary rate.

That's great thankyou ,

Another look today at progress with our GD spring Oat into failed rape trial this year.

Were they drilled at around about the same time? How much rain have you had since?

 

[colhonk]

Is there a lot less weeds / grass grow when using a GD to direct drill wheat? with not moving the soil to 3 to 4 inches deep to min till.

 

[Badshot]

On the whole.

Yes

But if there's lots of seed near the surface, you'll still get plenty.

 

[colhonk]

Anyone on here tried a GD on brick clay up my way?

Please don't.
Buy a narrow tine drill instead if you are starting out with DD. A Horsch with Metcalfe openers for instance.

I'd take the Vaderstad crop everyday on the value of the three photos.

We feel that the reason why the Vaddy looked better is because of the season and the hilly, wetter nature of that field.
@Warnesworth and I took another look at both today

Vaddy Field

GD Field
The worst bit of it. If the GD/ No-till will work here, It’ll work anywhere!

As bad as it can get and still ok!

The rest of this field

We think this is better than the Vaddy field now. All at ear emergence.

Edit: We have only had a couple of showers since the drought allegedly broke! The wet spot in the Vaddy field has never been a wet spot before last autumn. Nearly wrecked the sprayer boom by stupidly drIving through it last week putting some Manzi, Sulphur and Marriphite on it!

 

[jack6480]

That’s what my gd drilled spring barley looks very thin but nearly every seed taken

 

[Badshot]

Putting some manganese on today.
Used it as a full crop walking session to see what had gone up since it rained.
Very little I'd the answer.

Has anyone thought ofswapping the tyres for guttler rollers on there GD to improve slot closing

I've thought of it.
I've also wondered why they didn't develope it with them.
It'd crumble the top of the slot better meaning better emergence IMO.
But for minimal disturbance I guess the tyre wins.

Not at all. The existing wheels almost close too fine!
I would rather want some wider tyre to be used in the spring, so there will not be so much pressure right over the seed.

I think your right I think it needs to crumble the slot better especially in spring. I find closure good but it opens again sometimes because the slot is so clean cut
