Sunnybrook

Who has compared the performance of a Sunnybrook concave and cylinder with the factory set up? We harvest wheat and canola with a Lexion 760. I'm guessing the change would never pay for itself?

I second this question.

If Claas doesn't have an enclosed stagered bar cylinder in it yet it's a no brainer to install an aftermarket cylinder. Won't comment on concaves, that's an issue you have to work out.

I think where the sunny brook shines is in low cylinder rpm harvest conditions. Plugging the cylinder at low rpm is almost non existent. In the low rpm conditions I am hoping that it will also reduce the torque spikes on the counter shaft and drives with the inertia hopefully decreasing the risk of breaking the countershaft. It will never pay for itself with reduced grain loss or more acres per day. I have no experience with their concaves.

If you can justify air conditioning for a combine in Canada, you can make a SunnyBrook pencil out

If the machine would come new without a cylinder, or your cylinder was worn out or bent, it would also be easier to get into one, or better yet, get a good S.B. or Claas one from the factory.

I like that it runs true and balanced, not twisted with uneven bar height. I also like that the bars look much easier to change, and I think they are reversible. Slow cylinder speeds are more consistent as well. Lastly, I believe the large, deep spacing of the rub bar teeth help reduce grain damage which is important for me. I can't comment on the concave.

We run them with and without side by side and in wheat and canola there's zero difference in capacity.

It's the pulses you'd really see the benifit when you have to turn the cylinder really slow but even then we never used to plug the cylinder it was the APS that was the first to

Always being in balance is nice though.

I like the OEM concave better though.

This more relates to the older cylinder that wasn't enclosed? I never noticed the enclosed cylinder on my 2015 being out of balance. I guess for me now I would be removing a brand new cylinder to change over. Not sure what the resale market would be for the take-off?

Virtually zero.

Being honest may not get you a lot of friends but it'll will always get you the right ones.

...have an enclosed cylinder with v-blades and freshly balanced for sale. Changed it over to a Sunnybrook
