How on earth did you work out that it was under applying? Mine you calibrate and then whack in your seedrate; the first I would know would be if I ran a bag down from full to completely empty and worked back from the area meter(?)
Horsch seed motor - anyone changed it before?

That's exactly what I've been doing.
First thing I was alerted to was last year when planting some beans - bought enough bags to do the area at the right rate. Ended up with 5 x 500kg bags left over. Assumed something must have got stuck in the metering mechanism and thought no more of it.
Planted my first 25ac field this year with beans and found I wasn't going through the bags as fast as I had expected. Calibrated it again and it was still showing the correct calibration weight.
So I worked out what I should have used, worked out what I did use, then multiplied the rate up for the next few fields and it worked out much more logically. Have calibrated several times since and the quantity metered out matches that on the screen.
Swapped the roller over to the black wheat roller, same issue. Calibration works perfectly, but the field quantity doesn't work out correctly.
I can't remember the way to find the acres covered number on the drill screen which would make life easier, but the GPS screen records the area so I do exactly as you say, record the number before putting each bag in and work out how many ha it does between each bag. Can double check that too by working out how many bags should fit in a 10/12/15/20 ac field.
Currently I need to put the rate about 50% or so more than what I want it to be.
I had a Sulky unit suffer a failed motor earlier this Spring.
the permanent magnet had become un-glued in the motor housing.
it was replaced under warranty but I managed to glue it back in as a temporary fix.
i would imagine a partial failure of this type would add drag to the motor but it would still run. In my case it made an unusual noise during 1st calibration and then failed completely when doing a second calibration check.

If the motor has gone lazy i would expect it to draw more amps. The muller box tells you the amps at the bottom of the screen. The other factor is the radar telling it how fast to turn.

Ouch. Is it a muller screen? If so just press the ‘i’ button for area covered.
So yours must be a single hopper drill as hopper is not air tight. So called venturi type injector?
And for sure there is no air leaks in wrong places in that system?
The seed meter roller in our 4m dual hopper Pronto does not fill properly if there is an air leak in the hopper.
If your seed calibration process is done right and your meter is turning right while drilling (RPM seen on screen and someone watching on the drill while driving) then what else could it be than meter roller not filling right?

They are if twin hopper or triple hopper units

This is the screen which I think is Muller.
Can’t say I’ve come across or noticed the ‘i’ button before.

Now you’re asking….! I think it’s the third button down on the right hand side when you’re on the home (work) screen. It shows seed used, area covered, time taken and something else. I’ll get a pic tomorrow if I remember

Your page Alomy 75 is a bit different to mine (2005 Muller box), on mine, the "i"nformation button is 2nd button up from the bottom on the right on possibly the page you go to when you press the top left hand button showing the meter, to start the calibrating process.

Good thought. I will double check that again in the morning.

Thank you both.
I shall take a look for that symbol tomorrow.
Seed used and area covered would be very handy indeed. I can record both, drill a bag, then record it again and see what is doing what.

Could be a different software version; I think mine is 2011. It will almost certainly be somewhere in any event
I find mine very useful to work out when my seed is going to run out (no camera on mine). You’ve got me worrying now tho as I’ve got a drill filling trailer I’m refurbing…I’m not going to have a clue if my metering goes wrong… 
This is going to sound daft as you'd see an overlap on the GPS screen, but you haven't left the GPS implement width set to 6m for a set of rollers by any chance?
It's the only thing that I can think of that would give you a correctly calibrated seed for a 4m drill, but leaving you thinking you need to up the seed rate to 150% to correct it for the (incorrect) area sown.

Good logic there. The GPS is set to 3.9m.
Even on basic maths the seed rate is out. First bean field was 25ac (9.6ha), aiming on 250kg/ha so should use 5 x 500kg bags, but 3.5 x 500kg was plenty.
The idea of setting up a camera to count the revs/min whilst drilling might be a good next step too. See if the screen matches what it’s actually doing.
I tried to count the 60rpm it’s set to do when calibrating (empty) but it only doing 53/54. Horsch did seem to think that mattered though.

That’s interesting…if your radar speed matches your gps speed then it can only be that motor speed sensor can’t it? As you say-the calibration speed is usually 60 so it presumably ‘thinks’ it’s doing 60 whereas in reality doing 53/54. Weights would tie up but the ‘distance(=rotations)’ travelled would be wrong. But only by 10-12% by those figures…..unless it’s an intermittent fault
