Got an Atlas SF4 compressor running 3 vms, done 23000hrs n sounds like scroll is on its way out and at £6500 to fix and at 8 year old machine doesn't stack up.
What do other people use and do is have to be oil free for the robots??

A few farms near me, have put in kaeser compressors when their SF4 have given Up. Min oilfree compressors, but added a couple extra filters to remove potential oil.

I would say £6500 would more than buy a new compressor because when I replaced the scroll on mine for around £1500 I also got the GX4 which is a screw compressor. The 2 run together to run 4 robots. The GX4 wasn’t even £6500 either.

That's what I thought, oil free compressors bloody expensive, the firm dealing with said they had some GX4 with all the filters on working on lely farms and working well.
Has the GX4 got a drier? Have you had any problems with oil getting in the line?

Yes has a drier I think but then we put SF4 and GX4 through a descant drier to get dew point down low enough. No problems with GX4 so far and it’s done 14000 hours and old SF4 going well still helping GX4 out. SF goes from 6-8 bar and GX goes from 8-10 bar I think.

What are people's thoughts on the guided v free traffic systems. I know it's been covered before, but having seen many different farms I can see the benifts /downsides to both.
Final stages of planning for 4 bots in green field with access to grazing on 1 side. 2 groups with 4 rows of cubicles feed on the outside.
All thoughts /advice greatly appreciated.

Setup needs to be better with free access.
Free access cheaper to install but higher concentrate costs.
More to go wrong with guided system but much easier to pick and handle cows

It seems to me that a guided system would be more efficient from a labour point of view, however it seems to be harder on cows feet and more bullying may occur.
Guided seems to be easier to train heifers and the robot should have more free time.

Have anyone of you heard of 4Dbarn and Mr Jouni Pitkäranta? He is a Architect from Finland, who designs barns.


www.cowhomes.com
(11min presentation of 4Dbarn)

He has written articles about His designs in various international magazines.

Free systems with swing gates so You can manage every thing yourself, there should not be a single daily routine in the barn that you need to wait for someone to give You a hand.

Any thoughts?

Had couple quotes for compressors, Atlas only 12 months warranty but could be 8 week delivery. Anybody know anything about Fleming compressors? bit more expensive than atlas better warranty and delivery 4 weeks.

Neighbour changes the time he feeds out at or the cows all gather up at feeding time to go through instead of a steady stream.

Could someone help me out with a simple question. Anyone with a Sf4 compressor with fridge drier.....does your fan blow away from the motor towards the compressor or suck towards fan motor. Replaced my fan unit assembly yesterday and I’m sure it’s now going the wrong way.
Think I need another fan

if its 3 phase just change any of the 2 live wires and that will change the fan direction
Will also reverse the direction of the motor. Not sure what it is connected to? @Spear

The cooling fans on induction motors are normally radial and it’s the cover that directs the air over the motor to cool.
Or is the fan you talking about connected to creating the compressed air?

It’s the drier’s fan. I’m sure it’s supposed to blow air away from it’s motor through the condenser fins towards the air intake for main compressor. But this motor sucks.
Reversing the wires is an option but it may result in fan unscrewing overtime.

Has anyone had any experience or is it even possible to replace collars (qwes?) on lely a4 to a Eid eartag reader and stand alone heat such as cow manager? 6 years on and out of warranrty and quite a few of mine are starting to fail. They seem to lose heat detection first and eventually Id... just thinking thought options before I ask lely for a price!

We have solved this problem on our farm in the following way - we have just developed our responders compatible with the robot. The responder is a regular radio frequency tag uhf range. Communication with the robot is done through a special adapter connected to the Lely antenna via can bus
The device is located next to the native responder receiver. I think? there won’t be any problems installing the responder on a cow’s leg where the responders are usually worn in your area .
Of course, there is no heat detection in these tags, I use them only to identify cows, as buying new Lely infrared respondents is too expensive. But on the other hand, there is nothing stopping me from buying a definition of any third party cow heat detection.

I’m attaching some demo pictures for demonstration purposes.

So far, I have tested the development on my farm and would like to try selling it. I would love to see any cooperation.

Speculative coverage on the gene editing consultation response

Written by Defra Press Office

There has been coverage today in the I and the Guardian, reporting on speculation around the upcoming government response to the recent Gene Editing consultation, which closed on 17th March.

A full government response, which will include a thorough analysis and summary of the responses to the consultation and which will set out our next steps, will be published in due course.

Gene editing has the ability to harness the genetic resources that mother nature has provided, such as breeding...
