form one solid block, like 

 the oak sills in a well con- 

 structed house. There are 

 no bolts to work loose, 

 and every part of the 

 engine is held securely in 

 perfect alignment. On 

 these beams is solidly 

 mounted the crank case 

 which contains the engine 

 and the other essential parts. 

 The strains on a plowing engine are enormous. It must stand 

 the work, for breakdowns which cause trouble and delays are 

 dangerous and costly. The design of the oJl^^^ puts every pound 

 of metal used where it is needed to meet the strains, and the metals 

 used are of the finest cast iron, steel and semi-steel of our own 

 formula. 



ACCESSIBILITY 



The lubrication of all bearings is well provided for. The 

 governor itself runs in a bath of oil that needs to be renewed but 

 once in three or four months. In addition to the most complete 

 possible protection from dust, we have combined accessibility. 

 By simply removing the cover of our crank case all the vital parts 

 of our engine are exposed to full view and are within easy reach 

 of the operator. The cylinder head has no spark plug or other 

 device attached to it, so that it can he«.rem oved in two minutes. 

 Every other part of the engine can 

 be reached easily and quickly. 



The O'/^f can carry in its 

 tanks fuel enough for a ten 

 hours' run. Both the oil and 

 water supply can be increased 

 to provide for continuous 

 operation over a longer period 

 without taking on fuel. 



Our engine is so built 

 that it radiates the heat without evap- 

 orating water. Either water or oil can 

 be used as a medium for carrying heat 

 from the cylinder wall to the cooler. In 

 the construction of this cooler we have 



followed new scientific principles, thus accomplishing the desired 

 result with the minimum amount of metal and liquid.
