How dry is horrendously dry?

Our harvest conditions are almost always on the dry side for canola harvest. Grain moisture is usually under 6%.

I set my rotor and concave clearance to evenly load the sieves. (Slowing the rotor and/or closing the concaves shifts material right, speeding up the rotor and/or opening the concaves shifts material left). The only way to really check this is to do kill-stalls.

I think I was running around 550 RPM and 21 mm clearance.

Your fan speed is about what I run, seems like your lower sieve is too tight though, I think I set mine to 6-8. Top sieve 12-14.

One thing that helps with extra dry canola is not threshing it any more than you have to. I run slotted concaves in the #1 position, left and right, to let the already threshed material get out of the rotor cage. I'll often put cover plates over the #4 modules to keep excess material off the sieves.

 

Ok thanks, I’ll play around with it some more

 

I feel like 400 rpm is too slow on the rotor

Our canola was pretty dry this year, 6-7% moisture. Automation had the cylinder running as fast as 700 sometimes, vanes in slow position. Concaves were at 10mm. No cracking. This was Invigor pod shatter stuff, so kind of hard threshing.

Fan was 700, top sieve was about 11 or 12, bottom was about 8 and sample was decent.

How fast are you going? We just put along in canola. The slower you go the less the rotor throws out. But there are diminished returns going 1 mph.

 

I did just try speeding the rotor up to the previous suggestion of 550 and it seemed like the trash content got even worse. I will try your settings though and see if that makes a difference.

I’ve tried varying my speed anywhere from 3.5 mph to 5 mph.

 

Not sure what width you are cutting, but you may have to slow down further.

 

I’m picking up a 25ft swath

 

I don’t care what anyone say’s about automation. I love it! Yes I say wtf too at times. Lol.

 

Case 9250

Upper sieve 10/11
Bottom sieve 5/6
Presieve 3
Rotor 750
Concave 20
Fan 750 (can’t remember on this one.. could try low
Ease or medium threshing (vanes medium or open)

each day is different though! One day everything is dialed in and next it needs to be adjusted a bit.

although maybe the smaller the crop you need to bring rotor down more?
Sorry no expert but these setting for average to good crop have done really well for us if sieves calibrated.

speed is really important. Going too fast is never good obviously

hope it works out for you and doesn’t chip up too much

 

Your bottom sieve is way way to closed you need to be lift that crop mat up. I always run inverted sieve openings 8 on top 12 on bottom. Adjust fan speed until your happy and check losses

 

My settings for canola, haven’t started this year yet. Don’t be scared to use more wind.
Concave 18
Rotor 750
Wind 720
Top sieve 12
Bottom sieve 8
Pre sieve 1

 

Brand new to the 8230 this year, but some dry straight-cut L340 albeit tougher stalks in places, 5-8% seed:
Concave: 15-20
Rotor: 500-600
Fan: 600
Top sieve: 8
Bottom sieve: 10
Pre sieve: 1/ closed as it can be.
Spreaders 500

We added the top sieve curtains between wheat and canola so not sure whether that helped or not. Also removed 4 straight bars from rotor and replaced with spiked rasp bars. SW,SW,LW,LW. Pretty decent average loss of 0.5bu give or take across the width. The drier conditions got during the day the more I'd open the sieves, slow rotor, open concave, didn't seem to hurt sample and losses stayed low. 40ft header somewhere around 650bu/hr which seemed a good pace for the grain cart.

 

82/92** case all they can do for a good job is 650/750 bu hr. Top’s!
You can go faster but it go’s out the back real quick after 775/800 bu hr.

 

Vegetatively, this season offers a vastly different plant structure on canola than past years.
The seed to stalk ratio should(?) be much higher and perhaps larger seed and/or more seed per pod?
Perhaps raise t/hr at suitable loss levels?
Perhaps raise t/hr at suitable loss levels?
Going to be interesting.

Swaths around here are basically all pods. Not much for tall stalks this year in my area. Yielding decent but 2 weeks of hot weather is making the stems super brittle. Hard to keep the tank clean because it all shatters in the feeder house. On the plus side even lumpy spots in the swath are going through like butter.
