Given all the negatives I've read about Hisun on this forum I certainly don't want to come across as a shill for them. Maybe I've been lucky but my Sector 750 which I bought new in Jan. 2021 has been running fine. However, I only have 65 hours on it so far and don't push it too hard - snowplowing in winter (350x12' driveway), winching logs and hauling firewood on my 75ac. I keep it stored out of the elements in a shed.
Good luck with the search.
