Claydon and stones

Had a claydon on demo to put 30 ac spring barley in. Did a nice job, apart from its pulled a lot more stones up than plough/ combi drill does. 8-10 inch size stones that the power harrow would knock down and go over have all ended up on top. I know a tine drill is always going to be worse for stones but wondering if anyone has experience of running a claydon on stoney ground, once you have been through a few times does it stop pulling as many up? Am keen to get away from the plough combi drill system as I don't think it's doing our soil any favours and don't think a no til disc drill is suitable for us.

Any experience of advice appreciated.

Thanks Joe.

It does get better. But some of our fields took 3-4 yrs to get back to what we we would pick up behind the p.harrow/drill

Have had claydon 4 years and it will get better, we have stones. Dont feel claydon is as good for spring cropping due to wider spacing but only an instinct at the minute. very happy with simplicity of the drill and firm trafficability of the soil for following spraying etc

@Brisel would have a few stones I think but gets on really well with his (y)
Thanks for the tag (y) Do you still use a Claydon?

Flints, sandstones and the odd concrete block that turns up in the horse muck here. Yes, the tines do pull them up and even the heaviest rolls don't push them back down. The flints shatter down but the concrete and sandstones need picking up. When we were ploughing and min tilling we had the same problems but softer ground to push them back down into with the rolls. We still did plenty of stone picking then too. Overall, it's no worse IMO. Certainly not enough to put you off unless you intend to grow peas on rough ground and then have to scrape them off the floor!

Angled power harrow tines will tend to push stones down.

Ditch the leading tine put discs on for cereals you wont be bringing stones up from depth .. only ever use the leading leg for o.s.r n contract bean drilling ..

6m claydon comes in to do our spring beans not to bad for stones as pick them up when I see them but did see a lump of concrete split in 2 by the claydon once.

Well for perspective, we picked this load and about another 1/3rd of a load off 12ac. We would normally have got 1/2 load of same field.

Edit. It was pretty dry conditions which always make sones worse for coming up.

One quick question while we're on the subject of stones & Claydons. What pressure do you all run in your Stone Release rams? Mine was set to 100 bar but we were breaking lots of ram bolts, then I had to crack off a pipe to fit a new bolt so dumped the pressure via the spool valve. The book says 10 bar but Claydon say 80. Now I've opened the tap to let some off the system won't stay pressurised. No leaks. :banghead:

My neighbour bought a Claydon this year, and it did send shivers down my spine, watching them spend days picking stones. Reminded me why we stopped using any tined cultivators on our ground. He did say it was better the second time over.

Do many people use discs instead of leg?
not sure if many do, we do at every opportunity .. originally the discs were bought for going thru lots of trash and cover crops, just use it as much as we can now. no stones brought up from deep n probably less weeds (that's more a personal feeling that any scientific proof) . obviously the a share is still moving quite a bit of soil down to seeding depth but nothing below that .

Did you use disc from start? Or do you think it worked better because soil improved.

used them from the start following a cover crop the video is on claydons website, that was originally our plan to use the discs just to drill into covers. used the tines once or twice for drilling cereals into stubbles n then we thought we would see what it was like on light land with the discs .. the rest is history farm practise is use the discs for cereal and some bean drilling... tines are used for osr and contract work mostly now.... one customer did ask for the disc over the tine..

I guess our drill is different to yours as we only have a sealed ram on each leg or am I thinking of the wrong bit?? We only use ours in the autumn now for OSR and cover crops. We also have a Kongskilde stone picker! (y)

Project Lamport 2020

  • 152
  • 0

Project Lamport, now in its seventh year, is the UK’s leading R&D trials event. The original concept aimed to develop a cultural approach to blackgrass control, but has since evolved over the years. The site now explores improving soil health, as well as a comprehensive research project that investigates the impact of cultivations, compaction and cover crops on soil structure, organic matter and microbiology.

Expect weekly updates on Project Lamport, allowing you to participate in the entire journey rather than just the final product. These updates conclude with the official Project Lamport site demonstration and a live Q&A with our experts on the 15th of July.
