Turning a Motor Grader into Five Tools: ELEVATING GRADER ATTACHMENTS

摘要

The original elevating graders were drawn by stock, and tractor-drawn elevating graders were used into the 1940s before being rendered obsolete by the advancement of scraper technology. But unlike many other obsolete machines, the idea of the elevating grader experienced a revival in the 1950s and early 1960s as the concept was adapted to motor graders - which, for sake of convenience, will be called parents, following the example of manufacturer Jebco. Also, the elevating grader attachments will be called EGAs for short.
