Knight trailed sprayer

[jh.]

Got a new to me sprayer. It's a 2003/4 with linkage mounted steering drawbar .

Anyone any idea to what model it is? . It just says 3000litre trailed in all the paperwork and old MOT's

I take it they need quite a few revs to get induction bowl sooking . At 400ish pto like my old sprayer it's painfully slow but bang it up to 540 and it at least keeps up with the rinse nozzle .

Also the main tank drain looks quite vunerable , being almost as low as tractor pick up hitch . It's a lever type valve rather than like every sprayer I've ever had having a tap or pull cord , on the top of the tank . Would this be standard or possibly changed by previous owner. Any ideas for something less bulky with top tap/cord opener to save crawling under it to drain ?

Thanks for any info.

EU3000 I think. Mine has a pull cord on the top and only sticks 2 inches max below tank but sometimes its a bit temperamental when sealing shut- ie it can leak. I would guess its leaked and someone bolted that underneath? But you must remember that Knight sprayers are hand built so all are slightly different.

I usually fill at 450 rpm, seems to suck fine.

Think I would put a 90 elbow, then a bit of flexible hose then put the tap in a better place, far to vulnerable as it is!

If it's tracking drawbar then it's an ES, the EU's had steering axle.
We had one a few years ago, good sprayer

Oh, and make sure you use the check chain in top link to stop drawbar bending the PTO

Tidy looking yolk for its age, Es3000 just keep an eye on the pivot pins and bushes in the linkage yolk if your doing a lot of road work, tank drain would’ve normally had a sliding gate valve on them

Depending on the system the pressure needs to be as high as pos to make the induction suck.

Yes watch the bushes

The knight we had on a Clayton self propelled the induction hopper was excellent it would take anything in and very quickly as well

Thanks for all replies.

It is flow based as far as I can tell. Switch master on with boom sections off and the compressor comes on and brings the system up to pressure. I put RDS controller to manual and put pressure up as high as it would go but didn't seem to make much difference until the revs went right up . The RDS delta doesn't seem to read the pressure like my last sprayer did , I could manually bump the recirc pressure up to say 5 bar for flushing , the knight recirc seems to be a suction based system.

Shouldn’t need master switch on to help induction hopper, just pto and the ball valve in correct position

Just put master on to get pressure in system but as I said didn't make any difference as far as I could tell anyway.

Had another look and don't have any old ports on the top of the tank for a pull cord type drain , so possibly had a sliding gate valve as mentioned.

Also looks like it literally had 1 careful lady owner from new [emoji848]

what are the chances

It did [emoji12]

You owning up to fitting it lol

It started off in Berwick upon Tweed but doesn't say owned by bobthebuilder but there is an R initial in owners name

 

[Bobthebuilder]

It started off a little bit further south than Berwick, but ended up at Kelso, did you get it off Kelso Lothian harvesters or A M Phillips

 

[Robt]

It’s flow based if it uses a flow meter for feed back only. It’s pressure based if it uses a pressure sensor for feed back.

AMP but viewed at kelso harvesters
