Mighty Tonka Dump Trucks 1964 - 1972 Original Concept

Tonka was on the grow in 1964. Manufacturing its first truck in 1949, Tonka was establishing a reputation for a durable, tough, realistic toy. Tonka's first series of trucks would become known as the standard or regular series. This series stood alone until 1963 when Tonka developed and marketed the Mini Tonka series. Mini Tonka offered kids an alternative to the larger regular series, both in size and price. At the same time the Mini Tonka trucks were on the drawing board, another series was also in the design process. Had there been sufficient resources, both series may have been introduced at the New York Toy Fair in 1963. Waiting one year was well worth the wait however. At Toy Fair 1964, the Charles Groschen designed Mighty Dump debuted. And the rest, as the saying goes, is history.

The popularity of the Mighty Dump in the 21st century is without question. It has withstood the rigorous test of time and sandboxes everywhere. A whole series of Mightys followed model #900 Mighty Dump over the years. Each model a testament to durable, made with automotive grade steel, kids toys that were guaranteed for life. This portion of the website is dedicated to the Mighty Dump, 1964 to 1997. If you are a Mighty Dump enthusiast, they will be presented here with a few details to help you identify the year of manufacture. You may be inspired to collect one of each.

Collector Book and CD Cover A comprehensive reference book was authored by Mark A. Vaught and published in 2008 detailing the 1964-1983 Mighty Tonka series. The book was rather pricey at almost $50 US but did sell out and will not be republished. However, there is a less expensive alternative. I have been authorized by Mark Vaught to sell the book in CD form. Clicking the image of the book and CD cover to the left will take you to the FOR SALE PAGE. The information on the CD is much, much more detailed than what you will find on this or any other website.
