Combines 8680 canola setting help pleaseIJ

I had trouble setting my 8680 also for small seeds, but I put a small seeds kit in it and that made it a whole new combine for small seeds such as canola. The kit costs about 400.00, but there isn't much to it. If you could find somebody else that had one you could copy it for next to nothing. It takes about half a day to in stall. I run my wind at 1 with the kit in place and it seems to work well. All the kit does is reduces the air flow over the sieves. Hope this helps.

Where is the loss coming from the shoe or the walkersIJ We've never had any loss problems before. Harvested 30 bu canola at 7-8 mph, no problems.

I tried the small seeds kit we have two on our machine which one are you talking about. One the handle is couple inches of bottom of frame other is up a foot and back a foot was told one cuts air down to whole system and other just to the accelerator rolls.what cylinder speed and concave clearance shoe settings

I have both kits in too, but I only use the one that slows the air down to the accelerator roller. I have a Sunnybrook cylinder in mine so I'm not sure what speed a normal cylinder would run at in canola, but I run my cylinder at 300 with concave setting on 12 or pretty much wide open. I have a none ajustable air foil sieve on the top and I run my bottom sieve just about 3-4 slots open on the adjustment lever. Hope this helps.

we have the gen2 sunnybrook cylinder in ours. You ever plug it up with the concave that open wouldnt be much room for cleanout. I'll try them setting if it ever drys up.

Under tough conditions you may want to run your concave tighter and your cylinder faster. This is what I had it set for last year when it was so hot and dry. Never have plugged the cylinder yet.

I would also be careful running the cylinder too slow on the C62_8680..not sure if it would be a problem with canola but doing white beans( navy beans) I have had problems with the rear beater wrapping and breaking the drive belt that drives the beater...gives you very little warning...you'll hear a bit of rumbling in the back and before you have time to react it will break the belt...(has happened twice in the past 3 years)...also not a fun job to clean it our either. I think 300 rpm should be ok but I wouldn't run it much slower... Also..just wondering has anyone ever blocked ther cylinder on their 8680...I can't recall ever coming close to blocking it..a lot of inertia when you get that thing humming.

thanks for the help this site is great.do you like the 8680 I'm starting to dislike ours upper feeder chain jumped what a pain to get back also hard to tighten clean grain elevator chain.We have 1100 sep hrs Conveyor belt screwed again thinking about a 8780xp or a 2388cih gonna go see what differance they want,

I had a lot of trouble with the upper feed chain jumping (and breaking conveyor bars) when mine had around 1000 hours on it...the problem turned out to be worn cylinder bars...replaced the cylinder bars before last season with the chrome ones and have had no problems since. (I also replaced the upper feed chains at the same time because they had gotten stretched from constantly trying to push the material into the cylinder)... another symptom of the same problem was a lot of backfeeding..the new bars cured that too. I went through a lot of aggravation before I realized that the worn cylinder bars were the cause of the problem.

Put plastic slated feeder chain from harvest services in C62 as rocks destroyed the metal slats. No problems with chain jumping at all with that system. Machine runs quiter and smoother with the plastic. Not as good at feeding short crop, but it won't suck in the rocks from the header. Rocks sit between the feeder house and feeder auger rather than working their way into the combine. Dealer came out and drove the machine with the plastic and really liked the way it operated.
