Combines 7700 Chopper

On later choppers, the rear upper deck is longer, and fewer vanes are used. The new style vanes are much deeper and longer. There were a couple of aftermarket kits available to change to new style widespread. Or new upper deck and vanes from 7720 would work. In beans are you sure the narrow band of trash isn't coming from the shoe------need chaff spreaderIJ My 7700 spreads as wide as 8-30 bean head. Also had to go to chaff spreader to aid no-till in spring. Just a couple of thoughts. Hope this helps.

Does your combine have any aftermarket parts on it. I know that it is not the chaff because when we cut wheat the straw is spread about the width of the rear axle. We can did through the straw and find the chaff below it. We have set the hood all the way down, just as the manual says, turned the good side of the hammmers over, and replaced knives and nothing seems to help. Thanks for any suggestions

What did you mean by set the hood all the way downIJ

The hood that the spreading fins are attached to. It can be adjused up and down. The manual said that the down setting would spread it the best. It helped a little bit but it still wont spread it very wide.

On our 9500 we run it level in soybeans. We only run it down a little bit in corn to keep cobs from flying a half mile. I wouldn't think it would spread too well directed down. We run a 20' head and it spreads almost all the way out.

You said you turned the hammers over. I have a very worn chopper that throws stuff back up on the walkers-I read that can be caused by the rounded off hammers. I was considering turning mine over as well. Are there any problems with doing thatIJ

There is no problem doing this. Once one side of the hammer is worn, you can turn it over and run the good side out so that you get a finer chop. Around here, it is a common practice to get more use out of the hammers.

The manual said that it would spread it better when they are down. Do you have the long fins on your 9500IJ If you do they are much better than the factory fins that came on our combine.

Mine has the factory fins on it. It is a 1995 model. Wouldn't having the spreader board aimed down cause the straw, etc. to hit it first and thus lose it's momentum coming off the chopper hammersIJ I'm sorry, but I'm still having a hard time with the manual telling you to do that. I would think that having the spreader board in this position (down) would cause it not to spread as wide. With the board up, the material only hits the fins and is directed out. By the way mine also has the chaff spreader, but I can see the material coming from the chopper in my rear view mirror. I see it landing almost as wide as the header.
