My point which you confirmed, is there are no 95x0 models in rice country or used for rice, at least very rarely. You will find the 95x0s in corn areas. And the reason they were not used for rice alot, was power.
I will have to defer to a tech or someone else to help confirm the higher hp models. They all used the same engine, but they came in two power options, 215 and 235 for 9500, and 220and 240 for 9510s. If they are corn machines, they probably have the higher hp for unloading on the go and the extra hp corn uses over the wheat or small grain models. A dealer or service dept should be able to run the serial number and build specs for you and tell you the hp, or they could probably plug into the computer and find out.
