Knight trailed sprayer

This new sprayer sounds like a right pain in the arse.

Landquip still help me out with my 1997 build sprayer. Supply all parts too.
Phillips had 3 visits to get it moted. It seems a good solid sprayer just something not adding up , either operator f**k up , RDS setting or machine leaking internally.

Was supposed to be moted at start of month , then due to problems never got done until 15th , thought we had it sorted but still haven't been happy enough to actually do a load with chems yet

Spent a hour trying to work out pipe runs today , using laser recirc from clean water tank seems a very slow draw . Can see why bob thought it never cleaned much

it's worked fine for 14 years so i dunno what you've done to it :unsure: either give knight a call or ring john at wallace of kelso who's MOT'd it since new
All we really did was replace the faulty one way valves on the recirculation and replace the incorrect ball in rear for the right one but it's a second hand machine so understandable it would need something . Rest seems spot on .

Either that or the level gauge is not reading right but could only see that being a problem for fully full or empty , not in the middle like I'm using for reference

Did it work right even with wrong ball valve on that section . When they went to mot it , it wouldn't stop spraying until they fitted the correct one

it sprayed 150ac of winter barley with the "wrong" ball no problem
No idea then as Phillips drained the antifreeze and the 4 sections could be off but it was still spraying .

No blaming you in any way. Its an auld machine just trying to see where we have gone wrong .

It seems to all be behaving now other than getting the RDS to tally with sight level

it could be more to do with the switch for that section rather than the ball, like you've said phillips don't have much experience with knight machines so i would be more inclined to call someone who has
 
Surely it would be better to fill it to the neck and spray til it's empty rather than trying to spray out a few hundred litres sure if the tractor was on top of a stone when you are looking at sight glass it could be 300 litres out

Cheers for suggestions but no pony flow or even an ibc. Been filling in a level yard as just been plain water so same level/spot each time .

Had 1000litres on the gauge there and sprayed it for first time until fully empty and drawing air. RDS at 200 and only got to 4.6hecs .

Will dig out a 20litre can and start filling

for a 15yr old machine i doubt if you'll get it much closer :unsure:

Gauge is out a bit filling with cans . I had assumed going from 2000 to 1000 as a reference it would be consistent but hoping due to tank shape I just need to sort the string

George Wilson spraycare up the haddington way is your man for knight stuff he'll sort you out
Yeah he fitted the rds to the old case i used to use and moted whenever needed . Had asked him to find me a knight or case last year but then this one came up and it is a decent machine for its age . I had called him on Friday and got a chat , sent him some rds settings pictures and he had me check a few pipes said everything seemed good to go .

Convinced it is something simple and imo a rate controller when set right should be near perfect . The jug tests and speed checks have me convinced it is putting out the 200 a hec , just not getting backed up by sight gauge but maybe due to tank shape its maybe more out than they should be.

200litres filled with cans. Adjusted the string so level matched and sprayed it out to air . Maybe a good as I'm gonna get .
RDS totals 221litres out and 1.11hec. Backed up by a patchwork GPS

Miss this auld girl. No bad for a 1999 spraying 750arable and a few hundred of grazing and silage .

George fitted the RDS in 2007 iirc . Only really gave bother once and it was down to work ball valves

@jh. Do you know anyone with a weighbridge. You could fill it whilst weighing it to calibrate your gauge.
Had thought of that and now wish I had done it. Possibly still should but think I'll just have to go for it and see in morning. Already a week late with this pass now and way stuff growing the 23s are gonna do some damage but feared to change anything else lol
