In November 2012, commercial outdoor power equipment leader Scag Power Equipment acquired the Giant-Vac company. With the manufacturing, engineering, marketing and technical support expertise of Scag, the new Scag Giant-Vac product line will be brought to a whole new level of quality, performance and support after the sale.

Scag Power Equipment, a division of Metalcraft of Mayville Inc., was founded in 1983. Originally, the Scag product was manufactured under contract with Metalcraft of Mayville in Mayville, Wisconsin. In 1986, Metalcraft purchased Scag Power Equipment, marking the beginning of a tremendous period of growth for the company. 

From just one model, a gear-drive rider, to over 50 models today, Scag Power Equipment has become one of the largest independent manufacturers of commercial mowing equipment in the world. Scag Power Equipment's innovation and attention to quality is known and respected throughout the power equipment industry. Products are designed to be user friendly, with an emphasis on quality, performance, ease of maintenance, profitability and long life.

History of Giant-Vac

During World War II, a man by the name of H.L. Diehl went to work for Pratt and Whitney. Mr. Herman Diehl was part of a team that helped design and develop many of the early jet engine compressor blades. In 1948 venturing out on his own, he formed the H.L. Diehl Company in South Wellington, Connecticut. Having built several relationships over the years, Herman continued to expand his business with contracts from Pratt and Whitney, Rolls Royce and General Electric. The aviation legacy and reputation for the Company continued further expanding into landing gear struts for Sikorsky Bell helicopters.

Looking to design and build a product to call its own, H.L. Diehl became a pioneer in debris handling equipment and in 1959 developed the first walk behind lawn vacuum and leaf blower. For the next 10 years, the H.L. Diehl Company began to dramatically shift its focus to this new and innovative product and in 1966, the Giant-Vac brand name was born.

In 1969 Giant-Vac established in South Windham, Connecticut with the sole purpose of furthering its reputation in debris handling equipment. Later that year, the company introduced its first leaf loading machine and continued on through the years with additional innovations.

Today as Scag Giant-Vac, we will continue leading the industry as we take our top-quality debris management equipment to the next level of excellence.
