hitching device, not rotating around the horizontal longitudinal axis (roll), for the mechanical connection of trailers and implements
point along the pin centreline crossing the horizontal symmetry centreline of the drawbar housing The non-swivel clevis coupling shall be located as shown in Figure 2, mounted in the plane of the tractor’s or towing vehicle’s longitudinal axis. The centre of the non-swivel clevis coupling shall be located at the distance, t, rearwards from the end of the power take-off (PTO) shaft, in accordance with Table 2. The coupling shall be located as high as possible, without any part of the clevis/ring coupling or its construction (e.g. keeper) entering the clearance zone specified for the PTO in ISO 500-1.BS ISO 6489-5 pdf free download.
