Agricultural tractors - Test procedures Part 2: Rear three-point linkage lifting capacity

ISO 789-2:2018 specifies test procedures for determining the lifting capacity of rear-mounted three-point linkage systems:a) the maximum vertical force which can be exerted by the hydraulic lift at the lower hitch points throughout their full range of movement;b) the maximum vertical force which can be exerted by the hydraulic lift, at a point 610 mm to the rear of the hitch points on a frame attached to the three-point linkage, throughout its full range of movement.NOTE 1 A static test provides an adequate comparison between tractors. The test results are used only as a means of comparing tractors and not as a way of recommending the size of an implement which can be carried by the tractor.NOTE 2 This test procedure can be used to determine the lifting capacity of front-mounted three-point hitch systems.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
