Im from australia, and own a 9650sts and 936D. It has been a good machine to us, but I would like to try and get a bit more capacity out of it. Stripping most crops we have the back 2 cages of the rotor blanked off (except for where the grain loss monitor is on the left side of the machine). I am wondering about makeing up some covers to blank of the discharge beater as well to prevent overloading the sives. Has any one ever tried this before??? Can you give me any other suggestions to make it go faster!
