ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Society; princ

3、ipally agricultural field equipment, farmstead equipment, structures, soil and water resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management.

ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designated as “ASAE“

Standards designated as “ANSI“ are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American National St

7、andard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affec

8、ted interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised or withdraw

ISO 6508 (all parts), Metallic materials Rockwell hardness test 3 PTO location The location of the PTO axis shall lie within the shaded rectangle shown in Figure 1 and in accordance

21、 with Table 1, parallel to the longitudinal axis of the tractor and should be parallel to the ground within 3. The values of the dimension h are for normal agricultural applications (see Figure 1 and Table 1). On tractors especially designed for high ground clearance, such as working in standing veg

22、etable crops or sugar cane, hmax, can exceed the given values. On agricultural tractors designed for low ground clearance, such as lawn mowing or ground care which require a low centre of gravity, for narrow-track tractors, and for track-laying tractors, hmin, can be less than the given values. For

23、tractors that can accommodate multiple PTO types, hmaxshall be the value for the largest PTO type specified for the tractor.
