There seems to be slight realization on the part of the general public as to the general utility of the gasoline engine and the number of special purposes to which it is adapted outside of regular farm work. The fact of the matter is that there are large concerns in this country who devote a considerable portion of their plants to the building of engines that are adapted to many kinds of special work. The Cushman Motor Works of Lincoln, Nebraska, have met with remarkable success in the use of their two cylinder, 6-8 HP engines for hay press work, which is so constructed that it saves over 1,000 pounds in engine weight and 18 inches in the length of the baler as compared to standard outfits with standard engines. Satisfactory field tests with this two cylinder engine, which weighs less than 350 pounds, show that it is going to be especially popular for this purpose.
In connection with this article We show an illustration of a Cushman two cylinder vertical engine which develops 20 HP and is mounted on a homemade tractor built by Frank Potter, Carthage, Missouri. This 20 HP two cylinder engine weighing less than 1,200 pounds has been used by Mr. Potter in operating his homemade two plow tractor, which plows 8 inches deep and handles a disc-harrow in addition on the rear. The 20 HP four cycle, two cylinder engine which is used by Mr. Potter on his tractor has a speed of from 300 to 750 rpm, cylinders 6x7 inches, crank shaft 2? inches in diameter and fitted with a 26 inch flywheel. The governor is of the Pickering ball type, Schebler carburetor, low tension magneto, extra heavy double screened cooling tank, and a total height of 42 inches including base of 10? inches. This engine is especially recommended by its makers for heavy and continuous work where steady, even and reliable power is required, and the equipment is arranged for long runs capable of meeting all power requirements from 12 to 24 HP.
