So I have a gravely zt xl 48 that I bought 4 months ago and has about 40 hours so far. So by the end of this year I'm gonna geuss it'll be around 70 hrs total. I want to start saving up for a more commercial mower but my wife thinks otherwise. I know this mower isn't intended for commercial use. So the question is, how long do yall think this mower will last with me doing regular maintenance? 200hrs? Maybe 300 if I'm lucky?
