This document specifies safety requirements, test procedures, and establishes minimum acceptance criteria for the application of telescopic mechanical screw- and nut-type drawbar jacks and hydraulic drawbar jacks intended to be fitted on the implement tongue of interchangeable towed machinery 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.
