I know that a lot of people who own CaseIH combines have put hopper extensions on them and I have not heard any major problems. I want to put an extension on my 2188 and would like to know what to watch for as far as added stress on my combine. It already has 35.5 -32 tires on the front and axle extensions and the rear axle is set wide as well. I have heard that even if you are not in the mud to still run with the mud hog engaged to have the rear end help move the combine and take stress off the transmission and final drives. What is your take on this. Finally if any one has a fold down extension they would like to sell I would be interested. Thanks for any input.
