Congrats, i just read the thread and was gonna say step up to the 30. I only have 150 or so hrs on mine but love it. The only thing i would change is a 4 wheel drive indicator light. My place has about 1/2 mile of paved county rd on one side and darned if i haven't caught myself on the pavement in 4x4 mode. It's "operator error" for sure, but this operator needs an "idiot" light!
If your going to be mowing alot in tall grass/weeds, make sure you watch the temp gage. If it goes up at all, stop, idle down and clean the radiator pre-screens. If you don't she will overheat and spew radiator fluid all over.
The fuel milage will get better as it breaks in. I just hogged 8 ac of hilly pasture(1/4 in 4x4). It took 7 hrs & 7 gallons of fuel....not bad!
