Capello has been making lexion (cat) corn heads since they brought the yellow beasts over here.    The Capello head is a very good reliable head...... Put over 13,000 acres of corn through a 12-30......  

Don't know about the chopper, but I will say every chopping head manufacturer claims theirs takes the least amount of power.

 If ya put one on your 9500, I'd add an oil cooler to the reverser...... And check the oil every day.....  We took out two reversers on 9600's back in the mid 90's by running 8 row chopping heads.

 Good luck
