The average quantities of fuel and cylinder oil used per year and 
per 10-hour day by combines of different sizes are given in Table 29.

No kerosene was used, and the use of distillate was reported only 
seven times. The fuel consumption per 10-hour day depends largely 
on the size of combine and the quantity of straw per acre. The 
consumption of gasoline per 10-hour day for 9-foot combines aver- 
aged 12 gallons. For 24-foot combines the daily requirement was 
approximately three times that quantity. The requirement of cyl- 
inder oil was closely related to size of combine. The average costs 
of fuel, oils, and grease per combine per year and per 10-hour day 
of use are shown in Table 30.
