Jesse has an excellent point. The gas engine does rev about 1000 rpm higher than the diesel at the same speeds and workloads. With CVT, it does not take long for either to get into their higher RPM range, but the diesel has a rough redline at 3400-3600 rpm, where my 825 will rev to 6000. Most times, such as plowing, my 825 was around 3800-4000, but my diesel would have been around 2800 at the same speed and doing the same work. Another point for Keith, keep in mind though the Gator is not as heavy as the RTV, it is a heavy machine. My diesel, which had some accessory goodies on it, weighed over 1800 pounds without me on it, but full of fuel. Not RTV heavy but not far from it. I found in my steep hills, my diesel would struggle even unloaded maintaining speed. I did have aftermarket wheels which were larger in diameter and contributed to this sensation. Despite the fact the diesel would bog going up steep hills some, it never let me down even pulling a heavy trailer. It did, however, slow to near walking speeds in these cases. It would pull about anything, including a stuck garbage truck out of a ditch. My gas 825 will blast up the same climbs pulling the same trailers. There is a pretty big difference in speed and performance but as I noted earlier it is not free. It also weighs less than 100 less than my diesel so that gasoline engine is not all that light, either.
