Knight trailed sprayer

[jh.]

Think they had to get a new valve then strip it just for the ball to rebuild in old motor

How did you set that filter flush valve . Manual said fully in and a turn back out but would it not affect spray pressure too as seems to be on pressure side [emoji848]

Swap it over, it might’ve got mixed up when put back after cleaning

 

[Bobthebuilder]

I was never really convinced about the recirculating as there always seemed to be a bit of chemical in the end of the booms when cleaning [emoji57]

That's a good shout as chap had them all dropped to check housing seals

 

[jh.]

Seems right . Suction filter , pressure and then laser recirc closest to sprayer axle .

I've closed the pressure filter flush valve fully so it's not returning to tank. Both filters the same as manual .

Cheers for suggestion tho as can see how housings could be mixed up

Did you find any tricks for the best way to flush booms and recirc lines out?

With the old case trailed , I used to self fill on suction side with pressure valve set to spray , recirc set manually as high as it would go on rds and sook in about 600 litres . This would draw clean water in and through the booms back to tank . I'd then stop pto and drain out. Seemed to be only way with case but it won't work on knight being a suction recirc from main tank .

Sure sticker says to set laser draw to clean water tank but will it be big enough. Its maybe why you found it still with chemical but u maybe worked out some tricks over the years to help

not really, just did the normal wash out procedure and fill clean tank with allclear solution, never had any issues with residue chem effecting next crop

Master switch on and section controls off it says in manual. Not sure that I have noticed the difference myself.

did you get the narrow wheels as well or just gonna run it on the wider ones, not sure what width your running but we are on 72", the axle is marked where to move it into for narrows

Why move axle? Surely you set the centres of the rowcrops right and never change them?

 

[Bobthebuilder]

the wide tyres catch the side of tank when the axle is set for narrows at 72"

 

[Bobthebuilder]

the wide wheels are off a claas combine, same size hubs

I got both sets but looking out for a set of 14" to 18"s just to run it on all the time

Master on but does recirculation not only work when its off ?

And the tap set to draw clean water for boom wash on the side.

But if recirc only works when master off would that not leave recirc lines full of chemical from the one way valves on the boom sections

I’m just quoting manual but we may be at cross purposes

give knight a call direct, they are pretty good over the phone

Can't see them helping the 3rd or whatever owner , of a 2003/4 machine

Still seem to be going in circles trying to get it calibrated . Must be missing something unless it is somehow returning to tank .

RDS reading how I'd expect but sight level gauge still shows 100litres under dosing when spraying 4 hecs .

Anyone see anything I'm doing or done wrong ? . Gauge might be out when fully empty or full but surely consistent enough between 1000 to 2000 as tested .

Sorry about all the pics

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.
