SIDELIGHTS ON THE DURABILITY RUN
The plowing and hauling speed of the "Cub" is considerably faster than that of any other tractor, which accounts for its reaching Fremont many days ahead of scheduled time. For long stretches it averaged better than 4 miles an hour, pulling a 2000 lb. Mitchell Wagon trailer.
The fact that the "Cub" is spring mounted, both front and rear is, perhaps the chief reason why the machine was in such splendid running order at the completion of its long and tedious journey. All the jars and jolts received over rough, rocjy roads were not communicated to the motor - the springs absorbed them.
And the further fact that all the working parts are running in a constant bath or oil in dist proof compartments tells why the motor showed little or no wear when inspected at the end of the trip. Had not the working parts been thoroughly protected, the dust, dirt and sand in Ohio and Indiana would have worn and cut out the motor list so much emery.
Although many bridges were greatly weakened by the high water and floods the light weight "Cub" crossed all with perfect safety.
While the tractor was going 1000 miles the Hyatt roller bearings traveled a total distance of 43,160,000,000 feet. With plain bearings this would mean that the bearings' surfaces would have to slide 3 1/3 times farther than the tractor actually traveled. With the Hyatt bearings this distance was covered on flexible spiral rollers which accounts for the fact that absolutely no bearing trouble of any sort developed.
