Some market Class 5 hitches up to 17,000 pounds; however, SAE J684 does not contain a rating for this class. Pintle hook hitch system (another ty pe of conventional coupling system) performance ratings are covered by SAE Recommended Practice J847. It does not specify rating classes similar to the automotive-style hitches in SAE J684, but it does provide a performance test for hitch manufacturers to ensure the pintle hook and corresponding draw bar will perform to their rated test capacities. There are other factors to consider when determining actual vehicle maximum towing capacity. For example, coupling system capacity is determined by the weakest component in the system. Components in a conventional towing system include the receiver, draw bar, hitch ball and connecting pin. If the installed hitch is rated at a maximum of 10,000 pounds but the hitch ball is rated for 9,000 pounds, even though the hitch has a higher towing capacity of 10,000 pounds, the maximum trailer towing capacity is limited by the hitch ball's 9,000-pound rating. When determining chassis specifications for towing with a work truck, it's important to fully understand the truck body, equipment and payload. When assessing maximum truck towing capacity, it's also essential to account for correct matching of trailer hitch system components to the desired trailer and payload, since the hitch system can be a limiting factor for safety, durability and customer satisfaction.
