This document provides criteria for construction, establishes performance test methods and defines acceptance criteria for telescopic mechanical screw-type drawbar jacks and hydraulic drawbar jacks intended to be fitted on the drawbar of interchangeable towed machinery (as defined in ISO 12934) and hereafter referred to as "implement(s)"as original equipment or as replacement jacks. In addition, it specifies minimum markings and information for use to be provided by the jack manufacturer.

These jacks are used specifically for

— supporting the hitch points of implements during storage;

— lifting and lowering of implement tongues to facilitate attaching to or disconnecting from an agricultural tractor; and

— levelling of machinery for stationary use.

This document provides safety requirements, test procedures, and establishes minimum acceptance criteria for the application of telescopic mechanical screw-type drawbar jacks and hydraulic drawbar jacks intended to be fitted on the drawbar of interchangeable towed machinery (as defined in ISO 12934) and hereafter referred to as "implement(s)" as original equipment or jacks fitted with a jack attachment mount.

This document applies to implement mounted jacks or jacks fitted with a jack attachment mount. These jacks are used specifically for supporting the hitch points of implements during storage, lifting and lowering of implement tongues to facilitate attaching to or disconnecting from an agricultural tractor and levelling of machinery for stationary use.

The drawbars are those which are designed to couple with the mechanical connections of towing vehicles.
