We put a crary hopper topper (90 bu) on our 1688. It had the original extensions on that we took of. It looks like a long way for the incline auger to push up the grain that extra hight. Did anybody have issues with overloading the elevator drives because of the extra hight of the hopper and the extra load on the incline that comes with that? What did you do? Does an "incline auger extension kit" exist?
