First, accuracy is much improved the closer you can get the cutoff to the elevator paddle in the head of the clean grain auger. I would definately add the 1_2 link and get the upper shaft moved up and also raise the lower accordingly. Then I cannot stress how inportant it is that you follow the calibrations procedures. In addition, by adding the 1_2 link you can nmake some adjustment to the elevator chain on the bottom end and not have to calibrate. That cutoff controls how the grain strikes the sensor in the head. Change the dimension and you change the force on the board and you change the voltage generated and now the yield is way off. You should be able to cut the inclined auger, but would recommend you use a cutoff tool rather than a torch to avoid heat buildup. There is a conversion to move the mositure sensor to the clean grain elevator. Much improves crop flow, but can have heat buildup problems affectin the temperature probe. Not a big concern due to minimal affect on yield.
