I believe Morrison manufactured the Snowplow and Scraper based on a Rogers design and the completed item was marketed through the Newgren Company. As I’m no expert on these plows, or the relationship between these companies, this is all conjecture based on the brochures.
Here are several different brochures through the years and a couple Sno-Dozer data plates at the very bottom. This first brochure shows the Glenn M. Rogers company marketing the snow plow. This 1948 brochure does not mention the Morrison company.
In this brochure, also from 1948, it appears Newgren is offering a Roger’s plow setup that’s been combined with Monroe hydraulics (with three different hydraulic options no less).
There’s no date on this brochure, but in it Morrison is now credited with the manufacturing of the Rogers design, with Newgren still marketing the package. There’s no mention of the hydraulic options. I am leaning towards this being a circa 1949 – 1951 brochure. This brochure may have introduced the “Sno-Dozer” brand name.
