machinery from the dealer. The relation between proper adjustment and the 

 life of the machine is discussed. 



Investigation of 1,716 machines in service indicated that 60.6 per cent needed 

 no repairs. Although but 27.15 per cent were reported on the farms as in need 

 of repair, casual examination showed that 12.25 per cent in addition that were 

 not reported needed repairs, and careful inspection showed that 6.35 per cent 

 needed repairs in addition to those reported on the farm. Implements were 

 reasonably sharp with the exception of smoothing harrows. These were found 

 too dull for good service in 77 per cent of the cases investigated, with 7 per cent 

 too nearly new to be very dull and only 16 per cent in which the teeth had been 

 reversed or sharpened. In dry farming sections, 83 per cent of the harrows, 

 aside from the new ones, were sharp. 



Nine per cent of the farms investigated had suitable shops, and on these 

 farms the percentage of machinery not needing repairs was 71.36 as compared 

 with 59.25 per cent on those without shops. The respective percentages of 

 machinery reported by the owners as needing repairs were 22.4 and 27.7, those 

 discovered by the investigator 6.24 and 20.2, and those discovered by the investi- 

 gator on the machinery reported by the farmer as needing repairs to 7.15, 

 respectively. 



All machinery was housed on 22.15 per cent of the farms investigated, part on 

 39.6, and none except vehicles on 38.25 per cent of the farms. Closed machine 

 sheds were found in 19.46, open sheds in 34.23, and none whatever in 46.31 per 

 cent of all cases investigated. Machinery served as a hen roost in 74 per cent 

 of the open sheds and 31 per cent of the closed sheds, while other farm animals 

 had access to 19.6 and 10.3 per cent, respectively. The machinery was fre- 

 quently stored without proper cleaning and oiling. 



Plans are presented for an implement house and an implement shed.
