Are you keeping the extensions on at 28m or putting it back to 24m

It was a combined effort of KLH and AMP as a stop gap until our new 1 arrived, worked OK for last autumn but wouldn’t want to use it all the time like that

Yes and no imo. The standard break back is already 3m , so adding more to it seemed a bit ott long term . Different for a short time waiting on a new machine . The ones they made up where very well done though and solid . Next time I'm at farm I'll take a photo of them. Definitely not a quick botch for them .
Plus my trams have ended up a spout off set to get correct wheel width and have 3 shut off per side. Traming on even number means it's always same direction so it doesn't matter, odd number would have me traming both ways so highlight this off set . On boundary rather than put half width next to fence I now use full widths and then straddle narrow on the tram run and knock seed rate back to 70% as it's catching ins and outs anyway
Those are the extensions that got made up . Certainly not a 20 minute job .

ey, been a bit of thought put into them
Phillips have got it all moted . They fitted new one way valves in recirculation lines and a new ball valve , jug tested and all seemed good but going by gauge it's not working out right when I tried it over a 4hec field with plain water .
At start RDS wasn't liking switching sections off one at a time and would sound alarm . Target 200 but rate and flow both out , unless all sections on. Changed the valve type from "r" to "n" and now this side of things all seems to be balancing out. The sprayer does have recirculation but only activates I believe when master is off not switching off a single section in work.
Got that sorted and thought try one last plain water spray , expecting everything to be fine but at end RDS says I used ~800 litres so good for the 4hec but gauge saying 650ish actual. This was going by part tanks to rule out full and empty being slightly out .
Did a tank nudge thinking that would cure it but seems to change the nozzle reference pressure at the same time not just the cal factor , so didn't seem to be getting anywhere and swinging from under dose to over when trying again .
First RDS pic all sections spraying
Valve type "r" with 2 sections
Change to "n"
This got it all tallying up in work
Tank nudge . Tried a few loads but only noticed towards end it seems to change reference flow for nozzle , not just cal factor so going to start from scratch again tomorrow
Any ideas. It seems to be needing a higher pressure than the gauge reads(3bar) in work to apply 200l/h with reds at 10kph , almost like it's returning to tank someplace. I was wondering about the filter that flushes to main tank as never had one before but maybe something simple we've missed

Will double check in morning . I've read that many pages , charts and cards today I'm maybe wrong but thought it was 10kph at 3bar for 193litres

I even put on new pressure clocks thinking my own was faulty
Well that will save some head scratching as I was getting close by changing the cal factor but thought I must still have something wrong as was pushing pressure up to around 4 bar to get it agreeing with the level gauge

Just try going at 8 kph at 3 bar, I like spraying slower and looking around me, also it's much easier on the sprayer.
Yip . Been using bfs red for years too on last sprayer but with rate controllers , it's obviously just been banging the pressure up without me noticing in work . Probably only noticed it running higher today as I was on a new machine

If you've had the since 1999 are they not worn? Hence putting on 200l/ha at setting for 192.

You seem to be getting a lot more into the finer settings in that box than we ever did [emoji57] not sure which red nozzles your using, we had the hypro angled ones and were getting 200L no problem at @10kph and 3bar, I wouldn’t take that sight gauge as gospel either, we used to fill via a pony flow to give true amount, did you end up with a new valve or manage to find another ball for the 1 that was on
