RELIABILITY. 



The reliability of a motor truck, as that of any other machine, has 

 a very decided effect upon its profitableness. If a truck is out of 

 commission for several days at a time when its services are needed 

 and when its owner is depending upon it to help him through a busy 

 time it can scarcely be considered a profitable machine for him to 

 own. Likewise, if a great deal of time is lost on the road on account 

 of motor and tire trouble, breakage, and other delays, this loss and 

 annoyance may overcome all the advantages attending its use. In 

 order to obtain information as to the reliability of motor trucks for 

 farm use these truck owners were asked to give both the number of 

 days their trucks had been out of commission when needed during 

 the past year, and the percentage of the time lost while using them. 

 Table XVIII shows the average number of days 682 trucks of differ- 

 ent ages were out of commission during the year preceding the time 

 of reporting. The reports indicated that there is practically no 

 difference in this respect among the trucks of different sizes.
