1924-1927

A third size in the lightweight OilPull line was the Type R, 25-45 built from 1924 to 1927. Its 7 13/14 x 9 1/2 inch two cylinder engine operated at 540 RPM. The crankshaft was 3 7/8 inches in diameter with a total main bearing length of 15 1/2 inches. The new lightweight models used an improved carburetor with better heat control than in the earlier models. Three forward speeds were provided, and Rumely claimed this tractor was capable of pulling five to six 14-inch plows or a 10 foot road grader. No cheap outfit, the 25-45 sold for $3,200. Production began in 1924 and ended in 1927, of the 761 tractors produced only 98 are left, the R is able to pull five to six 14-inch plows under average conditions.
