I just wanted to add a couple more things. The machine is awesome in every way and luckily, my service guy takes care of me quick the few times there was a problem.
I would love to see #1 the stator more protected, #2 a filtered "snorkel" for the intake on the motor or #3 some sort of shield/hood system to protect the motor compartment more. The first 2 would be the most desireable.
My advice is to use high quality, low dust ferts and you will have hundreds of hrs of worry free service.
