acre being $0o019o The hay tedder is used only a few days in the 
seasom The repair cost per day amounts to $0,273. The average

THE BEAN HARVESTER. 
The bean harvester used in western New York is an implement with 
no moving parts, and lasts about 13 years, of which 29 days are spent 
in actual work harvesting 218 acres. If wheel bearings are properly 
lubricated and the knives kept repaired or replaced as they wear, 
these machines should last almost indefinitely. The data of Table 
XVII indicates that the amount of work done up to 45 days has little 
effect on the life of the harvesters.
