Around hereits either Simplicity or higher end John Deere, both are made locally. I'd give the edge to Simplicity as there are no 'cheap' models.
I have a 20 year old 16hp Simplicity (actual US made Briggs engine) that I swap a snow blower attachment on for clearing my 150 ft long driveway. I've used it at 10 below, always starts, traction is the onky issue I have, not power.
