To dual or not to dual

[DrWazzock]

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?

If its that wet and tacky ,with twins you will end up with one big one as it fills them ,,been there, T shirt to go with it ,,no fun digging them out .

Get really wide tyres and then dual them

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

I would go dual, but have the outers at an extremely low pressure.

 

[Matt Crooke]

We use them, I think it helps as only have to work the ground to a shallow depth.

Thing is I’m running out of time to pee about with them. My duals have too much tread on them but I have a bald set to fit on them instead. But I want to start tomorrow morning. The land is ploughed out grassland and I reckon will carry me well enough without duals. Just a power Harrow then an MF30 later. Not like I’ve half a tonne of seed on a combi. In a dry time I like the pressing action of the duals but it’s not dry now.

X2 600 on front
800+520 on rear
All at 12 psi

Lather the seed on alot thicker ,rough it in ,itll grow ,,as my old boss used to say ,,it wont grow in the bag .

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.

I’d agree with that. The plan is to do it all
With the MF30 then reinforce the cacky bits with the Carrier which will help bury it it.

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.

Heavy carr land

 

[Lincs Lass]

Heavy carr land

Alluvial silt over running sand ,,lovely stuff when its dry ,,like cat sh1t when it wet ,,sticks to everything

It’s not heavy though is it.

Varies ,,find alot of it in this area ,,its the ancient flood plains from rivers ..in a dry time it goes down like sand ,,subsoil it 18inch and crack it in all directions but once it gets wet ,,you work it once (well thats if you can )skip over it and go home ,,forget rolling it till spring when it bright and sunny .

Carrs are the remnants of lakes and bogs and are generally peaty.
Rivers and floodplains would generally be alluvial silt.
Neither are particularly heavy soils.

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

The farm I was on had 300 acres of it and can still remember every field from 20 years ago ,,all the dyke bottoms were full of orange ochre ,the reeds grew like stink in it but when the ditches were cleaned out ,,all the banks needed drowning in lime as nothing would grow otherwise .
Carr land is an education ,,it could teach something new every year

That looks quite clayey to me
