Smaller Cambridge Roll Rings = More Pressure?

I've not seen Vaderstad rollers working for a few years. Used plenty in the past and they did a great job except when dragging big stones. New ones take a bit of polishing up.
the main issue with the vaddys is there price, there in the fendt world of top money.
But after 23years using ours its been worth every penny

We bought a set of 8 .3 meter dalbo heavy rollers a couple of years back with the intention of putting the 60 CM rings and breakers on, until the dalbo guys were adamant that we would be better of with 55 cm rings for better consolidation. Rightly or wrongly we took there advice do a hell of a job in comparison to what they replaced .

its horses for courses, on light breckland soil you could not buy too big a diameter. Again rolling ploughing on heavy soil big rings. But firming soils in the spring on many soils a lighter set is desirable. What do your neighbours run?

I have a field not far from a sand quarry & in very dry conditions (like this year) if you aren't careful the 22” rollers can build/push up the soil in front of the rollers & bring you to a halt, it must have been a nightmare to roll with a set of gang rollers in those conditions, the Simba Freeflow drill I have does the same thing but worse because the front roller is a smaller diameter than the rollers

Just doing a major overhaul of our 12.3m Simbas from the mid 90's ! no one builds stuff like that these days, so heavy


Will start a thread but changing to a high speed, braked axle and commercial wheels and fitting slug pelleter / small seed / avadex application to increase establishment option in the future. Will be finished off with a fresh coat of paint. Turning into a big job so might start a pimp my rolls thread soon !

Got a few broken rings to change - any tips on getting them off shafts ???? !!!!!

Best to drop the gangs out and pull the bearing off the end and do it properly rather than smash the cast off with a sledgehammer (and wearing eye goggles!)

High speed means you need to consider suspension too... Fat tyres at the very least...

Would be an interesting thread always enjoy seeing all your projects and all done to such a high standard!

I did our 3m simba double press couple of years back, bearings in middle had gone plus couple of broken rings, tried all sorts to get the good rings off, rusted solid, only suggestion I kept getting was to cut/smash off the good rings to get to the broken parts, ended up doing that to 4 rings was isn’t ideal but buggered if I could see them coming off any other way, tried the soaking in oil/diesel trick, straps, ropes, bars, pushing with JCB and heat before smashing off and grinding a split in them to drive a cold chisel into so the cracked off. Not sure I’d want to do too many on 12m rolls!! :greedy:

Can’t do suspension (have looked but won’t work with the way they fold) but plan to put them on an axle that will take the big Michelin tyres we use on grain trailers so should be plenty of rubber under them

The wheels on it now (original equipment) are not up to the job even at lower speed - they heat up fast so if we go more than a couple of miles from home you have to keep pulling over and stopping and limiting speed a lot or a blow out is a certainty


Gangs are all off and mostly in pieces - there are a few rings sized solid though so going to have to cut some rings up I think

Standard tyres are way too small even on our 6,3m.

Fortunately our trailer tyres were a good fit. 440 is way better than 260.

If seized on I remember a Profi article suggesting lowering the gang into a pond and leaving it there for a week or two as it is often dust that seizes them and a good soak will make it soft facilitating disassembly.

Cut the rings if you have to, a few of them are cheaper than a new machined axle for your machine.

http://www.agricast.net/ are as good as any for price and quality( and on here !)

Pricing up a new 6/8 metre set of rolls with paddles and breaker rings. Larger rings weigh more but smaller rings have a smaller contact patch so apply more pressure or doesn't it really matter? I no smaller rings can stall a bit on soft ground but we're on heavy ground

Harry, as many have mentioned larger diameter rings are more popular these days for ease of pulling and overall performance. The weight vs contact area differences are more theoretical. It’s a good idea to look at the profile of the ring on offer and appreciate the soil contact it will have. Many manufacturers will offer rings that have less metal in the wearing edge of the ring compared to a traditional profile.

Breaker rings are a “marmite” option: love them or hate them. The main thing to consider is that they add about 20% more kg/m to a machine compared to plain rings.

I don't quite get this idea of shelling out a not inconsiderable chunk for big tyres on rolls......in the field I'm running them unfolded, it's not like a grain trailer that only ever runs on wheels so you want to spread the weight. The tyres are for getting it from A to B - up farm tracks and along roads.

If money were no object then yes maybe...but I can see an awful lot of other areas the money could be better utilised.

The idea is that wide rolls need a stable base when unfolding, we need tyres speed and weight rated to give no bother in long road runs, the rolls are very heavy (14t IIRC) so alternative would be a super single which wouldn’t be as wide (and stable) when unfolding

But most importantly of all I want as few different wheel / tyre combinations in the farm as possible as that means I carry less spares . All our Ttrs tut are in the sane wheel and tyre for this reason, it reduces down time if you have a problem (especially on the road)

In this case the spare wheels and tyres for our grain trailers might as well be “stored” on the rolls as sat in the workshop (ie we already have the wheels and tyres)

That makes logical sense and I can see the benefit of using tyres you already have....other than the hassle of swapping them over of course.

As far as stability goes.....surely that’s down to axle width as much of more than tyre size? Centre of gravity rather than footprint.

Either way though (and not relating to Clive’s situation) personally if I was buying some new rolls with new tyres I don’t see many issues with super singles to carry the weight on the road, and saving the cash for where it can get most bang for your buck.
