CIDE DICTIONARY
tractor screw,
A propeller screw placed in front of the supporting planes of an airplane instead of behind them, so that it exerts a pull instead of a push. Hence, Tractor monoplane, Tractor biplane, etc. This is the most common arrangement for propellers on modern airplanes. [Webster 1913 Suppl.]
