Has anyone checked the amount of fuel used per hour on a tractor of this size? I have used the heck out of mine this past week and it was working it. I cleaned out a horse corral and was running mine at around 2500 rpms in low range 3 rd gear after 5 hours the fuel guage just barely moved. The next morning I fueled it up and it only took 2 gals. Does this seem right? Oh and I am not complaining
