The Union Sure-Grip was rated 12-25 deprived of Union’s own four-cylinder engine. The motor was complemented by an Ensign carburetor of special design, along with a Splitdorf ignition system. The driver’s seat was spring-mounted and must have felt like riding a bucking bronco!
The Union Sure-Grip tractor was listed in 1921 and 1922. There is very little information available regarding this company.
