Would like to know how many leave sweeps in with corn and what do you believe the effect are on rotor loses? I installed the sweeps this spring and am hesitant about running them in corn. In the past without sweeps I would install two reverse bars unshimmed next to discharge. The rest of the bars were shimmer quarter inch. Kinda seem pointless to install reverse bars with sweeps. What is others experiences with this? Thanks

There was a guy a year or two ago that had Sunnybrook rotor with sweeps and he had a bit of rotor loss. He put in two reverse bar and the claimed he had no more than a five gallon bucket of loss out rotor all fall????

Finished corn last week with S78 and now in 80 plus bu. green steam beans. Rotor set with no reverse bars and 9 PFP sweeps. Very little rotor loss in 180-200 bu. corn at 15% moister. Even tryed 3 in thresher side to try and push crop over to first helical, didnt work so well, seemed to put extra load on concave, and rob power. Had to pull them out when started beans. The thicker matt was causing rotor loss at 400 rpm and robbing power. Next morning pulled the 3 sweeps off and away we went. All I can say i just Try it. Waist high green steam beans with a 40 ft. Dynflex running at 3.5 mph at 70% engine load. When I hit some spots that are dead that thing really eats.

Thanks for the info, seems to be working great in wheat so far. Also have reverse bars in. Will leave in for corn.

I removed reverse bars and installed sweeps in my r76. Started corn today and was afraid of what kind of rotor loss I would have and was amazed that it was so small that I don't know how you could get it any lower. All I could find was a few kernels here and there and I know some had to be shoe and header loss. On top of that was running less engine load. 8 row head in 220 bu corn at 17% moisture 60% load at 5 mph

Good to hear, yet another believer, my S78 is so smooth with that set-up. We got rained out again yesterday and when we got home there were two new class 9 case machines with 35 ft. heads in Dry beans that were close in yeild to what we are in. It was doing a good job on the ground also, but sounded like things inside were going all wrong, and moving slower than we do with a 40 ft. head. Now if only we can get what we neen from the factory.

Same setup with my r76 : cdf shimmed no reverse bar, 6 sunnybrook sweep and fast pitch on tresher side and lot of rotor loss in small grain but very smooth running machine 85% engine load

I have 9 sweeps 6 modified impellers and no shims. The way it was explained to me was that the last three sweeps that are extended into the discharge area helps keep things flowing. Without them the crop wads up and gets constipated trying to get shoved out. When it does this the straw gets chewed up more making it impossible to separate the grain
