Dual Wheel size for 3m drill

So whats the best tyre size for a dual wheel set up when running a 3m wide drill? The tractor is a 200hp size machine. Obviously we don't want wheeling sticking outside the drills working width but at the same time we want as much tyre on the ground.

Without having different size on duals I think you will struggle to get 18.4 r 38s within 3m on both tractor and dual. They will need to be quite close coupled and narrow track width. Our 16.9 r 38s barely fit in 3m

Thats what I was thinking. Currently on 650's and they are sinking in to much. I know its a wet year but we've always thought it even in more normal weather years. We could go to an 800 and stay within the 3m just but wondering if duals would be better. Perhaps not.

I've 18.4 r 38s dualed up and it is just slightly over 3m, although it doesn't leave a mark when cultivating or drilling. I think the tractor is on 64 inch centres but could be wrong. I don't want to make the wheel centres any narrower but could get away with trimming a little off the spacer bands perhaps.
The other way is to use step up/down wheels and fit row crops as duals.

use a front press?
if your sinking that much then its too wet or too fluffy

Tine drill direct onto stubble. The draft of it in combination with the moisture shows the wheelings up and the drill isn't quite filling them in, but as said you can also see it in more normal weather years.

I've got 90hp on 16.9 34s and it is spot-on 10 feet wide, 3.05 metres the way it's set up. I could go 4 inches narrower but it would be much less stable with the duals off I reckon.

It's only a couple of cm outside the coulter on a 3m drill so not an issue

Bigger machine you may struggle to have sufficient clearance between tyres to run 18.4s but could run pizza-cutters on the outside, maybe?

I have been using 16.9 x 38 wheels dualled on a 3m combi, they run on the drilling a bit, but to make any improvement wheel track would have to be too silly narrow to use tractor anything else.
I have drilled some fairly ropey patches tbh, and in none of them has the wheels pinching the drilling made any difference.

As already said, 16.9 38 is really your limit, I'm on 68 centres with 16.9 38s and slightly wider than the drill, duels do seem to spread the weight well though, have front duels also and the tractor treads very light, had to use another tractor on 750s last week when I did a field and they were spot on just slightly narrower than the drill on 68 centres, but our main drilling tractor does the ploughing also so that's why we run duels not floats, we are looking at changing to a bigger tractor on 650s for ploughing and drilling in the near future and think a front press will be a must for it when drilling.

A NH 7840 here on 70 inch centres and run duals with the combi drill they look wider but dont leave marks. The spacer may be a bit narrower than normal . I will be adding a front press for the spring sowing.

Have you got Tyre pressures as low as possible? You need to know your Tyre size and axle loadings. If you reduce your road speed you can go lower on most charts.

I ran duals 16.9 38s matched to 18.4s
But best thing i did was put a set off richie wheels converted to the front three point links as when out off work front wheels off the tractor would nrly be in the air ( you could lift front end by hand with a full bag off seed in hopper) thats with a load off weights out on three point arms
as i used a flexycoil spring cutivator fitted with rear hitch arms for 3mtr box drill
But as mentioned it was fare better when drill in work drop front arms all the weight went onto four wheels across the front you could see front end lift as tyres lost there sag (weight)
Made a good level 3mt wide rolled surface in front off drill
Then always drilled headlands last
Makes me laff all these massive tractors carrying 2-3 ton pluss weights down the fields
Either put a working machine on front or put the weight on wheels going down field when weight off the rear
Anything to stop ground compaction

You can, even easier if you have pallet forks available.
Biggest problem with them is when they get coated in sticky soil and fill the void between wheels with plasticine. It is then hells own job to clean them off. Would not want to pull out of work and go up road with them on our soil.

A man has pleaded guilty at Newtownards Magistrates’ Court to waste offences relating to a bonfire next to the electrical sub-station on the Circular Road in Newtownards, Co. Down.

Gareth Gill (51) of Abbot’s Walk, Newtownards pleaded guilty to two charges under the Waste and Contaminated Land (Northern Ireland) Order 1997, for which he was fined £150 each and ordered to pay a £15 offender’s levy
