Fantastic. I don't think you'll wear it out in your lifetime -- except maybe for tires. Kioti tractors with the 18-35 hp diesel engines have great reputations. I can only assume this has a similar engine, and a pretty tough frame. Figure on the engine outlasting you!
Have fun! You'll love it.
Edit: For winter use on my 23 hp Mitsubishi diesel tractor engine, I do add CETAIN booster to the fuel to keep it from jelling. If I know I'm going to need the tractor when the temp is below about 0F/-18C, I have a 200 watt heater (made in Canada) that snugly grabs the bottom the oil pan using a magnetic plate. I use it to make the cranking easier when the weather/oil gets cold.
