Vauxhall Alberta Canada | This is my 4th year with this machine and it has always been a problem no matter how I have configured it to this point. I have run the feeder house in both high and low any it doesn't make a difference so I leave it in low because it gives me a bit more time to shut it off if I hear it pick up a rock. I put the triangle and extended helical over the corner and then extended the helical further onto the separator grate. Adjusted the grate up and down no difference Tried opening and closing the concave also no change. The issue has to be in the separating end as the helicals in the threshing end don't wear at all just get a bit banged up over time. There are no reverse bars on the rotor and the separator end has tines just like a Pickett rotor. The beans I am having the most issues with are great northerns. The pintos I did this year before the rain were not as much problem could go around 2.7mph, with about 6% splits. The ones after the rain delay I struggled to get to 2.4mph and splits were closer to 10%. I think that the beans are more brittle than normal this year but still should not have this kind of damage. These are on irrigated ground and generally the beans are dry before the vines are fit to go thru a combine, dirt tag being the main reason. I am leaning towards the issue being the interaction between the separator tines on the Bison rotor and the steep pitch helicals. I think the vines are hairpining on the tines instead of being pushed along by them but can't tell if that is what is happening for sure. When I first had the sunnybrook rotor in it capacity was even less as the original style sunnybrook (I think) didn't have enough room between it and the cage for all the material to go through and any little wad would cause lots of rumble and plugging. | |
