1 Scope

This document specifies criteria for construction, establishes performance test methods and defines acceptance criteria for telescopic mechanical screw- and nut-type drawbar jacks and hydraulic drawbar jacks intended to be fitted on the implement tongue of interchangeable towed machinery [here after 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 an implement for stationary use.
