Farm Power And Machinery Management (Paperback)

Measures of agricultural machine performance are the rate and quality at which the operations are accomplished. Rate is an important measure because few industries require such timely operations as agriculture with its sensitivity to season and to bad weather. Completeness is that portion of quality describing a machine's ability to operate without wasted product.
As most agricultural materials are fragile and many are perishable, the amount of product damage or reduction in product quality due to a machine's operation is another important measure of machine performance.
Farm operators are very aware of the need for complete and speedy operations but they often ignore the economic penalties resulting from crop and soil damage. Quality as well as quantity must be considered when evaluating ma- chine performance.
