1910-1923

The Model E was the longest and largest produced Rumely Oilpull. It was produced from 1910-1923, of the 3,246 tractors produced only 94 survived. The model E featured a two-cylinder horizontial side-by-side transverse engine and is part of the heavy-weight class of Oilpulls. The 30-60 was able to pull ten 14-inch plows and would handle the largest separator built on the belt. It was in high favor with road contractors and comissioners as it was able to pull elevating graders, large blade graders, land levelers, and other heavy machines. Not only was this machine a powerhouse for the construction industry it also greatly improved farming as the growth of farms took off. This tractor had the ability to pull 8 to 10 plows through ordinary soil. The operation of this machine was smooth and steady despite the variations in size of the loads. Its reputation for pulling power was unquestioned. The two-cylinder 10 x 12 inch engine operated at 375 RPM, and Rumely rated it to have 30 drawbar and 60 belt horsepower. There was nothing cheap about this 26,000 pound monster — it sold for $4,300 in 1918. In Test Report No. 8 of the 30-60, Nebraska test engineers remarked that “ the tractor would have carried a 30 h.p. load for ten hours without difficulty”. On the maximum load test the 30-60 developed 75.60 brake horsepower, burning 10.73 gallons of fuel per hour; equivalent to 7.05 horsepower hours per gallon of fuel. Nearly as much water was consumed with the fuel mixture. On the drawbar test it developed 49.91 horsepower with a maximum pull of 10,025 pounds.
