HARVESTING MACHINERY 153 



13. Good oil should be used and all holes kept open. 

 In setting up new machines, kerosene should be used to 

 loosen up the paint. 



14. Any difficulty must be traced to its source, and 

 adjustment should not be made haphazard in hope of 

 finding the trouble. 



213. The transport truck. When it is necessary to 

 move the binder from place to place, it is mounted upon 

 transport trucks, which facilitate its transportation 

 through gates and over bridges. The trucks are set under 

 the machine by raising the machine to its maximum 

 height and then lowering it to the trucks. The tongue is 

 then removed and attached at the end of the platform 

 beside or through the grain wheel. Some transports are 

 more handy to attach than others. 



214. The tongue truck. Owing to the weight on the 

 tongue and the fact that the team cannot be well placed 

 directly in front of the machine to prevent side draft, the 

 use of tongue trucks has become popular, especially on 

 the wide-cut machine. Their use is to be commended, 

 for not only is the work made easier for the horses, but 

 it permits four horses to be hitched abreast. 



215. Width of cut. Binders vary in the width of cut 

 or swath from 5 to 8 feet. The 6-foot machine is the 

 common size to be used with three horses, the harvesting 

 of 10 to 15 acres being an average day's work. The 

 7- and 8-foot machines are used in localities growing 

 lighter crops and require four horses. 



216. Draft of binders. The following results were ob- 

 tained during the season of 1906 at Iowa State College 

 from testing a McCormick and a Deering binder cutting 

 oats. The ground in both cases was dry and firm. 



McCormick 6-foot : Average of three tests. .. .316 pounds 

 Deering 6-foot: " " " ... .312 pounds
