SUCCESSFUL FARMING 



belt horse power has no place under average farm conditions on the small 

 farm. This size should operate one fourteen-inch or two ten-inch plows. 

 It should operate a small threshing machine and also the small silage cutter 

 for silos not taller than thirty feet. This size tractor may operate a line 

 shaft from which power can be secured for pumping, grinding feed, sepa- 

 rating cream, churning, for electric lights and for many other farm opera- 

 tions at one time. 



In hilly land where irregular fields are sure to be prevalent and rocky 

 ledges are very likely to occur, the tractor has little place. As plowing 

 is the biggest job in farm operation, the tractor should in this case have 



its greatest usefulness 

 and should replace 

 about one-third of the 

 horses ordinarily em- 

 ployed upon the farm. 

 It generally takes 

 about one-third less 

 horse power to culti- 

 vate, harvest and haul 

 to market the crop of 

 any farm than it takes 

 to plow and prepare 

 the seed-bed in a thor- 

 ough fashion. Under 

 ordinary small farm 

 operations, the writer 

 believes that an 8-16- 

 horse power tractor is 

 the most economical 

 size. 



Tractor Efficiency. 



The tractor has been used for agricultural purposes long enough for 

 this fact to become well established; where a tractor of repute is employed, 

 more depends upon the intelligence of the tractioner than upon the ability 

 of the machine to do good work. This does not mean that one has to 

 have a college training in engineering or to be a master mechanic, but one 

 should know the principles upon which a gas engine operates and the 

 intelligent remedy of all diseases to which this mechanism is heir. 



Type of Tractor. It has long been proven that a multi-cylinder 

 engine is the most successful on the road for speed and power and it is 

 becoming recognized by the best tractor manufacturers that more than 

 one cylinder is more dependable and gives more constant power than the 

 one-cylinder type of motor. More cylinders mean more working parts,
