Hart-Parr's Old No. 1

Harold E. Gulvin.  Farm Engines and Tractors.  McGraw-Hill Book Co., Inc., 1953.

The original caption reads: 

"The old Model 1, completed in 1901 by Hart and Parr, weighed 20,000 lb and was rated at 22 to 45 horsepower.  Today, a tractor developing about 22 drawbar horsepower weights less than 3000 lb."
