I purchased the OS27 in 2022. Welded a 21’ trailer for the complete mill with 1 extension. Overall the mill went together well. For the price the mill works well. It was easy enough to put together and looks as though wearable parts should be easy to find. My biggest complaint is the Briggs and Stratton Engine. I could never get it to run correctly or idle correctly. Contacting Briggs or getting a basic manual is impossible. No warranty shops in my area. In the end I put a Predator 22hp on the mill. That engine was quite easy to install on the mill. The engine comes with a great manual and it runs like a top. At this point I would not recommend a mill with the Briggs motor due to my experience. But the Frontier part of the mill has worked well and does have a good manual.
