To dual or not to dual

[Lincs Lass]

No it’s blow away . As Lincs lass says cat shot or concrete. Catch it right can make it into an onion bed

I dont miss that stuff ,not one bit ,,its only saving grace was metal never wore out .

Bridgestone did a seminar on this and the calculation lasted about 15mins, basically it’s the total number of psi for the total field they were working out. Basically if I remember correctly this is a simplified version, say your tractor tyre is 650cm wide and you can run it at 15 psi, if you put another 650 tyre on you would need to be able to run them both at 7.5 psi or you are increasing the total load on the field. I stand to be corrected. In there experiments they worked out it was better to run a slightly narrower tyre at a higher psi (on paper) Up to a certain point, till you get to a sweet spot, but if you go too narrow it goes the other way. The biggest benefit come from having the biggest diameter of tyre you can. But to give you an answer to your original question the only way is to give it a go with or without and see.

If anyone can’t get to sleep tonight have a watch of this. https://www.cerealsevent.co.uk/videos/tyres-traction--compaction-6-may-2020.

Thing is round here every lower bit to a village is known as something or other Carr. And there's a world of difference from one Carr to the other.

Get really wide tyres and then dual them

I seemed to have gone the other way

 

[two-cylinder]

You haven't told us how wide your tractor tyres are DrW?

 

[bobajob]

I thought you were re jigging things, ploughed up and planted by the end of October?
and hopefully have the winter off farm and then spring crop what you couldn't get planted, an easier life and a change of scenery for a few months.
Its nearly December!
It's not a criticism of you, I think I would have given up!

Dual wheels front and back for all our tractors .all top work done with them fitted

We haven’t used duals since we bought our first challenger in 2000.
I believe that duals are much better than any IF or VF tyres available. Moving around however means a compromise is essential. In a ring fence I wouldn’t hesitate to fit duals and do away with track layers.

 

[its.... only me]

I would leave them in the back of the shed.they’ll help more if traction was an issue - than easing compaction. One set of tyres on wet soils are plenty. You’ll be fine if track eradicators set correctly. We’re still drilling atm. combi. on the ploughing & MiniFlow ( minus rear packer) on min- tilled - loam to heavy clay - hoping to finish oats this a.m. before the rain. Wheat poss. Monday onwards (weather permitting).............. as I have “a recovery situation that has arisen for tomorrow”

If that was Bridgestone with AHDB, I wouldn't take too much notice as they were just multiplying random numbers together and concluding that there was such thing as a free lunch.

Embarrassing and annoying that levy money was spent pedalling nonsense.

Why do you say it was nonsense, I say more common sense or money for old rope. . Even if the figures used were hypothetical. The theory behind what they were trying to get across is worth investigating. As some of the above posts have said sometime going wider with tyres has done more damage that good.

 

[glasshouse]

Is it better to squash down half the width 2” or twice the width 1”. It’s pretty wet so anything run on will suffer. The eradicators will dig out my wheelings to some extent.
Also they are big heavy barstewards that are an utter pain to get on and off, and often seem to be at the back of the shed.
My old uncle who farmed heavy carr land said they were a waste of time. I didn’t believe him at the time but sometimes I wonder if he was right. As long as you aren’t bogging down with then are they worth the rave?

You need mchale

 

[glasshouse]

Aye. I’ve used Terras in the spring for rolling and thought to myself I’ve spoiled more crop than if I’d used row crops. Same with the sprayer. Sometimes terras just spoil more rows. Sometimes trashing a narrow width is better.

Leave them off if its damp
Crak on

2x600's on front and 2x710's at the rear.

A bit like this!!!

So snipe , we averdex with a small tractor , it’s standard back wheels. 13.6/36. -750/16
Driving between tramlines on late drilling when it’s tacky some does not come and can see wheeling ,
So put some 850/34 Trelliborg that go on an old trailed Fert spreader and some small terra on front , 3 psi in them leaves a big flat foot print from the hockey stick tyre pattern , and by time it’s all through cannot tell where it’s been
We run similar to Bob Lincs but a vf row crop as dual , it treads very lightly with 750 on front also

Carr is a common place name around here too. Some people have commented how our soil seems peaty, others say sandy. It holds on to water too well when it is wet, but get it dry and it is an absolute dream. We get the ochre and the reeds in ditches too. There's various layers of sand and silt underneath of different colours, light grey first then orange, a thin coarse sand layer with cockle shells in it further down in places.

Think I read somewhere that below 10psi you don't cause enough compaction to worry about it?? Drop your tyre pressures as low as you dare and drive slowly to the field!

 

[snipe]

im not saying it im right or wrong just in some situation going wider is not always the answer. As you said you only had 3 psi which is very low. But some people are running duals at 10psi and could go down to a single at 15psi. But its all dependant on land type and condition don’t think you can say one solution fits all. But i don’t think you can dismiss a system just because I doesn’t work in your situation

 

[Lincsman]

I dual up when rolling and the rolls make marks in the wheelings, without them the ruts are deeper than the rolling marks, so isnt it a sign of less compaction?

Cripes alive, makes my heart sink just looking at it.
