scope:

This part of ISO 11001 specifies the essential dimensions for the attachment of three-point hitch implements to agricultural wheeled and track-laying tractors equipped with a three-point free link hitch according to ANSI/ASABE AD730:2009 W/Amd. 1:2014 or ANSI/ASABE AD8759-1:1998 and a U-frame hitch coupler.

NOTE In general the dimensions associated with the tractor and implement for use with hitch couplers are the same as those for the three-point linkage specified in ANSI/ASABE AD730:2009 W/Amd. 1:2014 or ANSI/ASABE AD8759-1:1998, and those for the clearance zone specified in ISO 2332.

The three-point hitch coupler systems constitute a special method of implement mounting. The hitch couplers are an additional component located between the three-point linkage and the implement, making it possible to hitch and unhitch from the operator's seat. Due to the special construction and function of hitch couplers, it can be necessary to vary the length of the upper and lower links indicated in the referenced standards.

This part of ISO 11001 applies to categories 1, 2N, 2, 3N, 3, 4N, and 4 of agricultural wheeled and tracklaying tractors as defined in ANSI/ASABE AD730:2009 W/Amd. 1:2014 or ANSI/ASABE AD8759- 1:1998.
