Our Mini-Tractor provides brake system certification so accurate it exceeds FMVSS121 and CMVSS121 requirements from the Department of Transportation and Transport Canada.

Since ASRAIII is expandable, you can start with our lower-priced basic kit
and add Hub Kits and components as your needs and budget grows.
