Weaving Big Disc

[H.Jackson]

Thanks for that half the acreage is on flinty downland so similar to brash, don't normally drill there till mid Oct (sems to give better results) so will be some time before we test it there.
Penetration not a problem once the discs were shone up here with only 40kgs of osr on board, but I can see stone's could be an issue, have to note @Pedders success with Mconnel drillerator this spring over the road on similar dirt confusion reigns ( lovely pint or two of Harveys tonight)

I would agree with spinning the wheels test

with 8m wide now at 9m wide it make no difference what the pressure gauge says if the hopper is empty the weight per disc is not enough in hard conditions but when it is like that slower forward speed and new discs help as does keeping the hopper 3/4 full iam looking into adding weights to the back of the hopper in place of the weights on the drawbar

I also had the same issue with a moore 6m drill when the hopper is less than 1/2 full

in brash soil slower speed is essential for dd

The advice on using the john deere in dry conditions in the usa was always to bang on plenty of weight. More is way better than less and it would be on the back too - can't see what it can do on the drawbar personally. Just some angle iron holding a stack of wafer weights can help.

In the case of the big disc water balasting the caddy tyres ought to add a lot to disc pressure judging by the way the weight comes of them when the coulters go in the ground.

Can't see this being required as you can put enough pressure on the coulters so that the seed caddy lifts off the ground which would be at least 4 tonne of weight.

I think it might be too dry to drill here with the 750a right now without weights into stubbles, will be fine where covers have retained moisture

Can get the entire weight of the drill on the discs but if it's very hard the discs won't go in

We will see next week, I have to option if filling the 2000L fert tank with some liquid N just as ballast to ad about 2.5t as Im not putting N under wheat

should have kept the dale

would have broken sheer bolts constantly in these conditions

Depends what you drilling into. If drilling into white straw, oat or wheat I think N helps. Had better establishment last year.

Other than oats the golden rule of my rotation is never to drill into white straw unless removed fir osr or in spring (after added cover crop)

Put water in the tank - placed irrigation to get it started, and extra weight

with 46 coulters 4 tonne seed plus the hopper and drill when empty less than 100 kg per coulter when the wheels are off the ground some of that weight is on the tractor

when drilling beans at 8m wide in 2013 with less than a tonne in the hopper depth was difficult to achieve and the tractor was too light on the back for good traction
when the hopper was full 5 tonne or more of beans there was just enough weight

water in the wheels is an option but when not needed difficult to remove

wafer weight just in front of the drill wheels will be looked at for next spring

with a 4m box moore drill empty weight is not enough

driving slower is the only option to maintain depth

it is now very dry and hard so unless it rains drilling will be slower to maintain depth and close the slot
there are still plenty of slugs out at night a closed slot is essential as a small amount of rain will lead to uncontrollable levels of damage

 

[H.Jackson]

Dry!!!!! first time yesterday didn't get an inch taller walking DD'd rape more rain forecast for the weekend.

As for weight the coulter bar is 3t odd before it goes on the caddy which looks like 4t of steel did leave some slots open till we wore the paint off and adjusted even pressure on the front and back wheels, easily filled with a rake and roll (except headlands need to cross them with the rake.

 

[H.Jackson]

first try today drilling wheat can now see where @yellow belly is coming from. very low disturbance but needs all the weight to penetrate wheel marks and speed causes the furrow to blow out, will try some adjustments tomorrow and see how it goes.

 

[Clive]

Think a 750a is 250kgs / coulter roughly ? That's not enough here right now in the dry for consistent depth so we have another 1500kgs on the drill right now which is doing the job taking things over 300kgs/coulter

I can now see why cross slot frames are filled with concerete !

Can weight be added to the weaving if required ? How many kgs per coulter can you get it up to ?

 

[H.Jackson]

You'd think with 7 t of drill and caddy plus 5th of seed 285 kg a Coulter only 175 kg empty although some of that weight will be on the tractor, trying to figure out a way of testing it on the weighbridge.
Not so dry here quite moist under the surface.

Thinking shorten the top link put more weight on the front wheel to reduce the blow out no problem closing the furrow. Will get some pics if I remember.

Done a bit now albeit into cultivated soils but we are running the 4 coulters behind each caddy wheel a hole deeper than the rest to get even depth across the width.

Definitely need to roll behind in on ploughed/pressed soil as it's not quite level enough and because it's quite cloddy (didn't press it quickly enough behind the plough) the clods from a row between the coulters alo most like a mini ridge so these need levelling out.

Into sumo/pressed soil it's a different machine though and seed/soil cover is easier as the seedbed is much finer. We are rolling but it's more cosmetic as the press wheels are doing a good job.

In both cases of cultivated soils the tractor and seed cart are leaving wheel marks as obviously not being a cultivator drill they are not easily removed, so this is a downside but something we've seen with a Horsch CO with big seed cart before.

We have just started running a 6M 750. We've got it weighted up to 275kg per disc and are running on maximum pressure. It so k but would like to see more penetration.It is not lifting the drill off the ground when fully weighted so i think more weight is not the answer. Does anyone know how to get more from the springs?

Yes you can't put a chock in the springs to get more out of them. Biggish job to do. Personally I'd put some more weight on again if anything (or wait for some rain)

Just drive slower. Better to do it properly at 6km/h than 12km/h and do half a job.

@fishtail - I use four of these behind coulters where the wheelings are. i'm sure you can pimp your own.
