I have a 30 Foot challenger 9250 dyna flex hooked up to my gleaner s98 that doesn't seem to sit quite right. With the head tilted fully forward the skid shoes on the divider ends ride on the heal. The front (after the curved part) is still about 2.5 inches off the ground. Does that sound right? I would think it should be close to parallel with the ground. When on soft ground it bunches up and drags under the skid. Eventually it starts to furrow or push dirt ahead of the cutterbar.

We also have a 9250 on our combine. That seems to be the way they run. Ours wears the plastic off on the back of the skid plate, and at night it wants to push up leaves and junk ahead and plug up. We drive diagonal to the rows in soybeans and that helps some. On the new header they supposedly fixed that problem. I'm not sure what the model number is, 9330 maybe? I'm afraid to ask how much a new one costs these days. Sickle timing is critical on that header. We found out the hard way that just because the letters on the 2 pto shafts are lined up does not mean the sickles are in time. They have to travel through the guards at the exact same time. We tore ours up. Still, I think it is wonderful compared to our old 8200 header.

Not overly familiar with that header/combine combo but my in-laws had something like that and heard them mention a wedge kit for the feeder house after they were experiencing harvest difficulties. You might want to check with your dealer and see if there was an update or any service bulletins that came about over time.

Your dealer should have a chart for what skids to run. There are high and low. Depends if you have axle risers or not and what tires you have. I used to have it somewhere would have to look and see.
