Having an issue with my seeding rate. Calibrated in the yard to 120lbs/acre, first fill too light by 5% so bump it up to 126 lbs. Second fill very close, third fill was over by 26 lbs/acre. First two fills were on the day the seed (barley) was treated third was the next morning. Is this normal? New to me tank with 519 monitor so not sure what is going on, maybe have to calibrate every fill.

Yes it’s normal for it to put more on after things get shined up. We always calibrate to get it close then seed 10 or so acres and recheck. Doesn’t matter how well you prime the augers it’s not the same as seeding then recalibrating. We have always done this on all our bourgault carts and have never had rate issues.

Also how do you figure you were light? Unless you weigh it going into the tank.
If you were light you should recalibrate not just guess and bump the rate up.

I checked the rate when I filled with fertilizer after about 64 acres. I used the drill the day before for wheat so everything should have been polished up. The barley was treated about 2 hours before the initial calibration so maybe was not flowing the same as a day later. I would have expected the rate in the field to be higher than the yard as the seed settled in the tanks, the actual calibration in the yard was 118lbs so figured it would be close to 120 in the field. The seed is very large and very heavy (54lbs/bu treated) hence the 120lb seeding rate.

Freshly treated seed is nearly impossible to meter accurately whether its through an auger or meter rolls and will usually be heavier than desired. Not uncommon to see wide variances even when performing a field calibration after seeding a few acres.

I agree. Treated seed can be like that and changes as it sits on the seed and drys up.
Of course there is the chance of gumming up your augers and having the seed go on light……… don’t ask me how i know

I guess I was expecting it to change maybe 5-10% not over 20. The seed didn't feel any different from start to finish but if it was gummed up and took a few hundred bu to self clean that make sense. Was worried that it was an issue with the meter, will just have to check more often. The barley was treated with raxil pro and was kinda sticky, the wheat was treated with the same and was dusty not sure why it was different. The wheat rate was consistent start to finish. Thanks guys.

Yep been a few guys here that ended up re seeding when the seed treatment gummed up the meters and thoroughly messed up the rates.

I think it says in the bourgault tank manual to compensate for a 8% overlap in seeding rate. When I treat soybean seed I will usually get it a day or two ahead of seeding just to prevent wet seed from gumming up my deere seed rollers. I agree with the comments above inn respect to shinning up the rollers and than recalibrating. Sometimes humidity outside can complicate calibrating as well. At 4 in the afternoon I notice oats really tends to speed up on dry dusty days compared to the morning. At some point it is a happy medium when it come to calibrating and allowing overlap and speed of seed thru the rollers. Sometimes I will select a different seed rate based on the monitors current seed rate and a just on the go.
On my 1910 tank I use 11% overlap and that gets me an accurate seeding rate. I am not sure why it is out after doing an acre verification.
Lucky to be seeding! We are a lake right now and no hope to seed to the end of May at the earliest!

So another year and more calibration issues. Calibrated in yard shaft 1 112lbs shaft 3 76lbs shaft 4 300lbs. Go to field 118, 94, 311 without changing settings try again. 155, 155, 318, do it again 157, 76, and 318. Not the first time this has happened, power to clutches is good and rate does not jump around much while seeding. Any ideas?

Your shaft speed seems to stay steady while seeding? I have seen transmissions start having trouble and cause odd problems. Shaft rpm would be unsteady if that was the case.

Could also check your calibration motor drive. If I remember correctly they are keyed on the one shaft and it can shear but still drive kinda. And perhaps the bearings on your meter auger that’s giving trouble.

Have you tried doing the calibration where you measure out 200 feet and drive the distance then measure the product? How far out does it seem after doing a full tank or is it pretty close? Maybe Meskie is right, it might be the calibration that’s out of whack and not the actual meters?

All the bearings, chains etc. seem fine and everything turns smoothly. I don't understand why my monitor when seeding says around 110 when my calibration shows around 155. If I slow down to 4mph the monitor reads about 132 and if I slow down to 2.5mph it drops back down to around 118. The two fert rates change a bit but not much maybe from 310 to 330 and 75 to 80. I had issues with it in barley last year as well. Wheat the last few days worked alright. So along with an autosteer system that isn't working and a bad blockage sensor seeding has gotten of to a frustrating start.

I’m guessing it’s a 591 monitor? Not too familiar with those but don’t you need to adjust calibration factor so it knows how much is going on per revolution?
