Load-Master factory at Culpeper, Virginia, circa 1973     An ownership change occurred during 1984 when Hackney & Son, an established vocational truck body manufacturer based in Washington, North Carolina, acquired Load-Master. Within a few years, the company was known as Loadmaster Corporation, Division of Hackney Industries. Load-Masters continued to be manufactured at the Culpeper, Virginia factory occupied since 1961. For the most part, only subtle changes were made to the product line during this period.     The most visible change was to the LM-100, which received squared-off tailgate lines, and the tailgate lift cylinders were relocated outside the body for easier maintenance. The hopper was now advertised as 2.9 cubic yards, though there had been no major structural changes. This was probably a result of a change in the way hopper capacity was rated within the industry, going from the manufacturer rating to the Truck Body and Equipment Association (TBEA) rating system. A heavier-duty version was introduced called LM-100 HC (High Compaction) featuring larger 4.75" diameter slide cylinders and a pressure regulated ejector panel. The packer control system was changed to a split-cycle to comply with ANSI standards, which were adopted throughout the entire industry.     The big LM-400 tailgate remained unchanged, but the body bracing was reduced with a single horizontal brace and fewer vertical pillars. Foreshadowing a coming change to the entire product line, the 400 also received an 'open front' treatment to the body structure. The LM-300 was the least-changed model during the period. In fact, from its debut in 1967 through the mid-eighties, it retained its original body and tailgate lines.
