It sure sits up off the axles like our 9510 sidehill does. I don't see the hydraulic cylinders though. Some other mechanism of leveling? To my eyes it says hillmaster and the machine looks like a sidehill from the height perspective.
im from the UK these combines are very popular, as bighammer says it is a hillmaster combine and the final drives rotate to lift or lower the combine, it compensates for 15% slope and then the feeder house will go for 7% giving a total 22% slope and the combine will still be level.
