Had the same problem with extra fine roller in canola and tag team. Switch to a segmented roller and all is good.

Had the same problem with extra fine roller in canola and tag team. Switch to a segmented roller and all is good. We have been warned in the past to not use a segmented roller ( don't happen to own one either to try ) due to issues they can cause with seed damage and from what I recall it all depended on the size of the seed as I believe the seed was going where it was not supposed to on the roller surface and crushing the seed, something unexpected and bad was happening anyway so from what I gathered it was a hit and miss result. I believe they were also bad for sucking through the roller when sitting still and the fan running, could be wrong on that. That is years ago I was at a flexicoil seminar and they were raving about the segmented roller and then a local salesman from a dealership pointed out the wrecks from some farmers experiences, they obviously didn't like to hear that but there it was. Zero experience myself from using one so no first hand knowledge, I believe Don Boles talked about them years back but can't recall the details now.

I mixed some 46-0-0 with the very small seed size canola (some was just under 4 lbs/1000 kernels) just to bulk it up. Couldn't set the meter rate slow enough to get the desired 3 lbs/ac with 40 lb bags of seed.
Plant stand looks good.

What was your method victory to mix the seed as one sure would not want that to not be blended well enough or separate out and have no seed come out. Not a product one would want to keep around for another year with some left over or would not think so.

Been using a segmented roller for over 5 years, never a problem with crushing seed.

Carlos, if you are sitting in a field with the fan running ( and you may not do this ) while digging for seed depth etc, have you found some seed piling up at the seed boots. I am pretty sure that was a complaint of that style of roller depending on what tank it was placed in and fan speed, air flow duct settings etc as there are always variables.

I have also been using a segmented roller in a CNH tank since 2015, zero issues with canola or inoculant. I was seeding canola at 2.5#/acre today, and it was bang on! The extra fine meter can swell from seed treatment or friction and lead to a stopping of the meter

Bourgault tank. Left the metering spouts in the calibration postion for a half mile once. Noticed a nice line of seed and fertilizer when turning at the end of the field. That was five or so yrs ago, maybe this yr we won't be able to still see the dark green line, ha.

SW, have you noticed any seed building up at the shanks ( or which ever openers you have ) if sitting there with the fan on and of course canola seed in the tank. With our drill we are using the middle tank which for some has not turned out well due to that sucking issue but from what we can tell it has not been a serious issue with the roller we have been using and only running the fan at 3000 rpm due to having put NH3 down prior so no need for a high fan speed given the more limited volume of fert and typically split that up between tanks 1 and 3 . May have to look into using a segmented roller in the future. Oh and SW, do you recall what shaft rpm your meter was turning at to only apply the 2.5 lb rate. Ours was turning at 2.5 rpm and put on around 4.3 pounds of product but that is an extreme slow turn rate. Maybe I should seed at 10 mph, that would get the shaft speed up ! LOL.

Some does puff out when the fan is turned on and off(I think because of a big pressure spike) and it does that on the wheat with the coarse roller too. Just when sitting I don't think any is coming out, and we are running 4400 rpm. Putting 100 pounds/acre of 11-52 down the same pipe as well. It seems to me that it's turning about 15 rpm but I'd have to check again to be sure. I can look in the book for the cal# too.

Not a product one would want to keep around for another year with some left over or would not think so. It's called elbow grease . Just got a plastic tub, dumped a bag of canola seed in and then half a 5 gal pail of 46-0-0, mixed it together by hand (took maybe 30 sec) and dumped it in the tank. Nothing fancy or scientific about it. I guess to get a better mix a guy should use equal amounts of canola seed and 46-0-0 (or whatever product a guy wants to use). The canola seed and 46 have about the same density surprisingly, so that should limit separation issues. I did notice a little separation after doing most of the quarter, but just mixed it up a bit in the tank again. There are so many little canola seeds going in the ground that it is quite forgiving. Would be nice to seed with a planter to get seed singulation. I have a bit left if you need some!

I assume the cal number would be different based on drill width, aside from all the other lack of precision .... oh wait, they call it a precision metering system LOL. But if you happen to note the roller speed for the given seeding rate and with that your ground speed and seeding tool width, that would give an indication of what could be expected from a segmented roller vs this extra fine low clearance unit.

Victory, I ran out of elbow grease a long long long time ago !, the production one would have to go through just to mix enough for a quarter section would be some undertaking and to pack it all up by hand into the tank with a bad back. Hopefully you were not using your bare arm as the stir stick as they may have put bad candy in with the good candy on the canola and besides your neighbours might think you are turning into papa smurf by sporting a blue arm

Sorry for late reply northernfarmer, just like SW said a bit when fan is turned on but nothing major getting sucked out by fan. Usually try to be at 2700 on velocity sensor.
