You have 275 acres of soybeans with an expected yield of 45 bushels per acre. The combine, with a 25-foot reel, travels 3.8 miles per hour. The harvesting efficiency of the field is 0.80.
a. Calculate the harvesting capacity of the combine using the following formula: HC = (S ×W× EFF ×Y)÷8:25 Where: HC is the harvesting capacity, bu/hr. S is the combine speed, mph. W is the combine harvesting width, ft. EFF is the harvesting efficiency of the field. Y is the yield, bu/acre. b. How many bushels of soybeans do you expect? c. How many hours does it take to harvest the soybeans?
