A. I always thought impeller plugging was between cylinder and impeller, the pinch points jamming the impeller?A. A walker combine may even perform better in green stem beans, because green stems can bridge after the impeller on R models, a walker would eliminate that.
B. The APS grates are easy to change. Make sure you have the large hole ones installed, round bar are better.

A impeller wear kit is a good fix until they wear. The sunnybrook is the cure.A. I always thought impeller plugging was between cylinder and impeller, the pinch points jamming the impeller?
Didn’t think any plugging occurs between rotors and impeller but perhaps beans are different.
B. Was going to try large 40 mm oval hole APS grates this year in peas, have used round bar but thought more open area better?
