The meters are very accurate IF you have round seed. The stock White meter with either the small or medium plate will plant round seed at 99%+ all day every day. We plant almost 100% of our seed with the medium plates.
Whites don't like Flat seed. Basically you end up having to pick your poison. One notch on the air pressure adjustment will make it go from having skips to having doubles. I usually chose to have 3-5% doubles instead of 3-5% skips.
As far as the 3/4" drive shaft and the cotter pins in the couplers, White meters turn very easily compared to a finger pickup meter, if you have trouble shearing the cotter pins, you have something binding up somewhere. Probably a bad bearing.
The cotter pins are the shear pins, they are supposed to shear instead of tearing something apart.
