This tickled me somewhat!

http://www.fwi.co.uk/machinery/bedfordshire-farmer-makes-a-success-of-controlled-traffic.htm

Mr Barnes admitted to deviating from the true traffic lanes a few times for a few jobs which is fair enough to keep the costs down but Tim Chamen came back with this:

You may have read an article in Farmers Weekly (UK publication) recently (5 May) about Barnes Farming and their CTF system, which they have operated since around 2010.
Robert it appears has been having problems with spreading of the light fraction on his combine (as do many others) and some of his clients have expressed concerns about this. In a pragmatic approach (and in the present absence of any improvements to combines) he has elected to switch the combine in alternating years between his main 12 m traffic lanes to those at 6 m, which are used for a proportion of his drilling each year. He also elected, for reasons of reliability, not to purchase the extra length of unloading auger that would avoid having to run his chaser “off track” during the unloading process.
These moves are unfortunate but understandable while the issues above are sorted, but they will be seriously compromising the potential and actual benefits he had been and could be getting from this CTF system. The update to CTF Case Study 9 (available to members) shows this graphically as well as the two photos alongside (or below on mobiles) which illustrate just how much damage one pass of the chaser does on non-trafficked soil. Rainfall infiltration will also be seriously compromised in this wheel track, which will actually be well over 200 m long for each unloading event if Robert’s estimate of 2 minutes for this operation is correct.
As far as the extra positioning of the combine on his 6 m traffic lanes is concerned, recent evidence from two sets of on-farm trials has shown just how much extra yield is lost due to the combine compared with where just the drill and rolls/cultivators have run. In a winter barley crop the extra loss was 23% and in winter wheat it was over 18%.
As far as the combine is concerned, Robert admits that he is compromising his CTF system because he can’t address the key issue of poor spreading performance. This is not confined to one particular machine, most combines with wider cutting platforms suffer from the same issue, as we heard from Keith Challen at one of our recent CTF days. In his case, he has added a second chopper to facilitate extra chop and spread but does have a cultivator in his system, which Robert does not. Keith has however also paid the price of an increased power requirement on his combine, which has been achieved by re-mapping the engine.
I believe that combine manufacturers should face the challenge of designing something better. Trying to spread light fraction effectively by throwing and blowing are doomed to failure because they are trying to defy the laws of physics. They should “grasp the nettle” and try a different approach!
So, if you are having a problem with your CTF system, ask the question, is it because CTF isn’t working or is it because something else in your system is compromising it? All agree that the principles of CTF are right and bring great benefits to soils and crops but “Rome wasn’t built in a day” and some weaknesses in the supporting systems need to be addressed for it to be able to perform at the highest and most sustainable level.
If you are interested in on-farm research assessing the benefits of CTF, would you be willing to “chip in”?
NIAB have been running some trials on a farm in Cambridgeshire but need £5000 to complete the work, which aims to assess the impact of CTF on soil structure and crop responses under different traffic lane intensities.
CTF Europe and Dale drills have already funded trials on traffic lane compared with bed yields involving 8 farms and are about to make results available to our members. But we need to support this more "in-depth" study, so we are hoping some of you will contribute to the work of NIAB. There are two ways you can do this. First by joining Smart Agri-Systems (if you are not already a member, just £30 annual membership) and second, by making a donation using the form on our Sponsors page. Any contribution you make will be acknowledged in the work and on any pages relating to it.
Our sincere thanks in anticipation of a bevy of new members, the re-joining of others and hopefully some generous sponsors!
Kind regards
Tim Chamen

I agree that combines need a rethink on straw and chaff handling somehow

I fail to see how you throw light chaff 6 metres either side of a combine without some kind of mechanical belt & spreader mechanism. You can't defy the laws of physics! @Goldilocks understands this & is raking straw at an angle to the combine with LGP tyres.

There's another way of controlling traffic - don't culitvate or sell the straw in the first place.

Seems a bit daft doing CTF but not having an auger on the combine long enough. CTF doesn't really interest me though as it's completely redundant if you can direct drill.

His reasons for not ordering the longer augers on his combine were ridiculous. On my 36m system with the CTF auger the tractors and trailers never leave a sprayer tramline, what's not to like especially on a wet harvest on clay.
I didn't really see the point of the email. CTF is a very basic thing really

CTF only really has an advantage if you insist on using big heavy machines on soils with no structure of there own (i.e. cultivated) , I spent time with Robert on a study tour to the USA last year and I think he saw that as your move away from such big heavy equipment in you establishment system and create soils that carry load better that there was less need to be so rigid about CTF. Seems after a few hours on plane with me he bought a 750a :)

He knows his stuff and what he's doing I'm sure, he is also a member on here

our combine is the weak link in our system - straw spears at 12m is rubbish - I have other brands on demo this year for this reason, Class need to up their game at these widths for no till farmers

Unless you have some kind of conveyor to outrigger spreaders I don't seem how you'll get an even spread that wide. The fine material is not dense enough to be thrown that far no matter how fast it leaves the spreader.

You'll have to get a rake :p

Exactly why I've gone for a 7.5m header instead of a 9m one, hopefully get full width spread of all material. Going to control harvest traffic and permanent tramlines, then light tractor on decent tyres raking @45 degrees. Drill with a claydon on the opposite angle.

Obviously 12m is to wide for ctf so why don't people run on 9m intervals as combines easily spread straw this wide.

My 10m system is at its limit for proper straw and chaff spreading ( and that is with a one year old Lexion with state of the art ,adjustable everything from the cab and wind sensors to adjust the left and right throw constantly! ) Still have to rake at an angle in certain conditions.
I seriously believe that 10m is the sensible max for CTF and does not require extreme engineering of unloading augers.
Still think that 3 into 1 Harvest CTF ( where grain trailers never leave application tramlines ) is an absolute no brainer for most farmers with medium to large harvest machinery, but agree with Clive that it is not necessary to get anal about establishment CTF if soils in good condition and the correct equipment is being used in the right conditions.
 
This picture pretty much sums up why it doesn't work very well at wider widths and it's not brand specific either.

Newish Claas combine can spread well at 10.5m maximum and it's supposed to be the best chopper/spreader on the market.

Found this interesting

Here in NW New South Wales & Sth Queensland, CTF & zero till go hand in hand together

The 2 most common sizes would be in multiples of 9 or 12 metres

The choppers in Aus dont have to handle straw from real heavy wheat crops though, do they? Maybe maize is a proper test?
