Hopefully you can still install 9610 ECU's into 9510's, like you could with 9600's and 9500's. This will give more horsepower on a smaller machine which helps in tough conditions.You could install the small corn pulley on the separator drive to reduce horsepower requirements. This is easier than changing the grate spacers and will still allow them to thrash small grain out.Also, installing the beater slow down kit in reverse and lowering the beater grate helps in tough conditions.Be sure to run the feederhouse conveyor chain on the slow speed side of sprocket to give more even flow into cylinder.Wong Yei (a very small Japanese fellow) is available slip into the ECU box and he'll serve you with more horsepower. Be sure to connect ECU with a constant supply of rice.
