Accord drill putting out more seed than calibration

[dannewhouse]

Any ideas?
Was drilling grass the other week and it was putting out nearly an extra 2 kg/ acre I just kept putting a bag in at a time weigh what left just before it ran out and compare to acerage covered no good though if not extra seed. Kept winding back each bag.

At the start I put PTO in and checked for blockages and seed was being blown out, not at propper rate but should be nothing as meter wheel was stationary. I waited 20 seconds just to check it wasn't sat there but it seemed to keep coming.
Stopped later. PTO in but nothing coming out?

Strip of belting/ rubber under the metering wheel. Mice had a nibble of it or just worn out.
Open the flap as if you are totally emptying the hopper and you will see it
It's always been related to that when I've had any issues with an Accord meter

rubber flap worn if putting 2 kg heavy just work out % out and cut it back
you will get a bit of suction and vibration of machine will affect it
0.2 gramms a metre difference

Think I've heard of that before I was wondering if I had a hole in the 4" pipe up into hopper but couldn't find one!!!

Andy guest best man for one?

I tie the calibrabration handle down as it can move whilst working , generally opening it up

this or the tyre has a puncture and going flat

Does you land wheel run true and stops spinning the moment you lift out work?
We have all seen drills dribbling out seed as turning on the headland.

should look like the pic above little buggers eat the whole of the curved bit off

Rats will also gnaw notches in the feed roller, causes seed to dribble out if it stops in a certain position, ask me how I know!

and if you are really unlucky they do the bottom of the venturi, the rubber flap and the vanes on the feed roller on their way through. Ask me how i know!

As everyone has said- it’ll be the rubber

 

[bobk]

Is it on fine roller

 

[nick...]

Have heard of roller housing flexing during calibration and then returning to original shape with seed movement and vibration.

We had that once ended up putting 15kg/ha of osr on. Checked tyre and it was v low.

Yes,flat tyre=smaller diameter which spins faster!

Have you reduced air flow on the fan with the valve?
