KV/Accord Drill Jams

[sahara]

We have a KV Evo Tine Seeder Drill.

Twice during drilling this year the metering unit at the bottom of the tank became jammed. Expecting to find some thing like a stone or a twig, we emptied the hopper and had a look, but we could find nothing, the metering unit was still jammed though. Alter much fiddling around we got the unit to move and meter out grain, so we continued to use the machine. A couple of days later the same thing happened, and again nothing obvious could be found.
Having a bit more time to investigate yesterday we removed the whole metering unit from the base of the hopper. There were bits of crushed grain everywhere, but nothing that I would have thought would be a problem. A thorough blow out with the airline has cleaned everything up and the unit runs smoothly, but sadly I am no wiser as to why the thing jammed.

Has anyone else had the same problem or has anyone got any ideas?

Thanks

Never had ours jam up completely like that, but drilling winter beans last year it got very close to jamming up. Made it hard work turning the calibration handle. Since found out for drilling beans this year that your supposed to fit a bean flap in the metering unit to stop them getting stuck. Went much better after that!. Always been fine drilling wheat though.

Have you looked at the seals on the bearings,if one or more were to part company with the bearing grain could get in between the ball bearings making it into a bruiser and difficult to drive.

Before re-fitting the metering unit, make a spacer to go between it and the hopper bottom on three sides. Say 4mm thick. You can then make a slide of 2mm thick sheet which you can slide in between the hopper bottom and metering unit, allowing you to clean out the metering unit without emptying the hopper.

Ours does that, I didn't know u could get a flap, any idea what they look like?

we have a new KV 600 evo ts and having left it out for a couple of days with wet weather on it, we found moisture ingresses through the hopper isolation plate, just above the seed unit and dampens the dust and grain round the bottom of the metering wheel, thus preventing the electric drive to work. Push slide in, open up flap exposing cell wheel and clean out crap and it has worked fine. Was surprised that it took a bit of wet mush to stop it working but once cleaned out no problem.

We were using double dressed seed when it jammed, this does feel a bit wetter that just SPD so may be this extra moisture was the culprit.
I must admit that when I finish for the year I air blow out the tank and the easily reached parts of the metering unit, but I have never done the metering unit really intensively, as this is now its 5th season for us may be the accumulation of bits was too much for it. An intensive blow out is now on the end of year clean down list!
Thanks for everyone's comments, and ideas.

This is the bean flap, in John Deere packaging, for the Accord metering unit

Was going to take a photo of ours for you this afternoon but didn't get round to it. There will be a black flap in there at the moment which you have to unbolt and remove. Then just replace with the blue one for bean drilling. We wasn't sure if the blue one could stay in for drilling wheat or not, so have decided to swap back to black one for wheat.

Our KV has a metal u shaped deflector plate that fits in above the metering wheel I think. bit of a fiddle to put in but doesn't require bolting in. must confess we haven't used it yet but the drill was delivered with it fitted and the fitter took it out before we started on wheat for the first time. not 100% sure of my facts so my apologies if I have mislead anybody!

Depends on whether it is original accord metering or the new kv Eldos metering. Accord you swap from black to blue the kv eldos there is a metal flap that fits in above the metering. Also the eldos has different rotors sizes similar to the horsch.

Yes spot on.
