Drilling with tractor-drawn drills was reported by six men. This 
work amounted to an average of 106 acres, or to 2.9 per cent of the 
total tractor days per farm. Only one man used his tractor for 
all of his drilling. A two-man crew was used on all tractor-drawn 
drills. 
Harvesting and threshing with tractor-drawn combines was re- 
ported by 21 of the 31 men. Various sizes of combines were used, 
depending mainly upon size of farm and size of tractor owned. In 
all, 13.6 tractor days or 26.8 per cent of the total tractor work per 
farm was represented by harvesting and threshing with the combine. 
The man labor for this operation amounted to a total of 65.3 days 
per farm. 
Eleven men reported miscellaneous work such as moving buildings, 
and moving the tractor from one job to another, which amounted 
to less than one tractor day per farm.

HOME BELT WORK 
There was little belt work done by the tractor. It consisted entirely 
of feed grinding and amounted only to 0.5 man-days and 0.3 tractor- 
days per farm. No doubt these farmers would use their tractors 
for more belt work if there were more to be done. No tractors were 
included which were not used for some drawbar work. This excluded 
several high-wheel tractors, which were used almost exclusively to 
provide power for stationary threshing. The kinds and amounts of 
the various classes of tractor work and the proportion of the im- 
portant drawbar operations done by horses and tractors are shown 
graphically in Figures 2 and 3.
