SAVE MEN SAVE HORSES SAVE MONEY SAVE WORRY 



The latest development in labor 

 machinery is the HART- PARR GAS 

 TRACTOR, which is revolutionizing 

 farming methods. They displace many 

 men and more horses, and are always 

 ready for service and eat nothing when 

 standing idle. Think what it means 

 to have cheap power and plenty of 

 it, always at your command. You 

 can use these Tractors for plowing, 

 discing, seeding, harvesting, threshing, 

 hauling, hay baling, feed grinding, 

 running irrigating pumps in fact, all 

 kinds of heavy farm work.

SAMSON TURBINES 



When the PUMP cannot be direct connected to the tur- 

 bine shaft, the power is usually transmitted by gears, 

 shafting, etc. On account of the HIGH SPEED of the 

 SAMSON, for a given power, lighter and consequently 

 CHEAPER transmission machinery can be used.
