I help my uncle on his farm and he has a John Deere 9500 combine. This week we were running soybeans and the combine is really bogging down. It struggles to combine a full swath or go up an incline. It seems to have lost quite a bit of power. We changed the fuel filters and that really did not make any difference. Has anybody experienced this or have any suggestions on how to resolve this issue. Thanks for your advice.

Also look at the cylinder bars, a little wear on the bars in soybeans will take alot of power.

Don't forget to check the air filter.

Check the strainer in the tank

Where the fuel pulls out the tank, there is a slotted screen that plugs into the valve. Two people, one to take it out and use a finger to stop the fuel and the other to blow it out w/ air hose.

Besides all the above good suggestions, how are the beans?
Green stems, tought to run through? 1.5mph harvesting speed is not uncommon even with STS's.

The later 9500 was availabe with higher hp. What version does your uncle have?

The beans are in good condition. The stems are not green and not matted down to bad. The machine just seems to bog down under any load. I think the combine is a 1995 version.
