No. 11. Yes, this was the big show tractor in 1873 with crawler and power-lift plows. A Pennsylvanian named R.C. Parvin came out to Illinois and California after demonstrations at two Illinois State Fairs in 1872 and '73. A company was organized with office in Chicago and factory in central Illinois to build it. At least one was sold and used by a big California land owner after Parvin had demonstrated it near Fairchild in that state. Parvins inventions and developments covered several years and include a combine harvester.
