BS ISO 11001-4:1994

This standard BS ISO 11001-4:1994 Agricultural wheeled tractors and implements. Three-point hitch couplers is classified in these ICS categories:

• 65.060.01 Agricultural machines and equipment in general
• 65.060.10 Agricultural tractors and trailed vehicles

This part of ISO 11001 specifies the essential dimensions for the attachment of three-point hitch implements to the rear of agricultural wheeled tractors equipped with a three-point free link hitch according to ISO 730-1 and a bar coupler.

NOTE 1 In general, the dimensions associated with the tractor and the implement for use with hitch couplers are the same as for the three-point linkage specified in ISO 730-1. Due to the special construction and function of the bar coupler it infringes on the clearance zone specified in ISO 2332.

The three-point hitch coupler systems constitute a special way 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.

This part of ISO 11001 applies to categories 2 and 3 of agricultural wheeled tractors as defined in ISO 730-1.
