A ribbon-cutting ceremony was held in Yosemite Valley, Thursday, July 23, to commemorate the arrival of four hybrid tractors that will be used in the popular Yosemite Valley Floor Tours. Acting Superintendent Dave Uberuaga and DNC Parks and Resorts at Yosemite, Inc. Chief Operating Officer Dan Jensen cut the ribbon as 60 park visitors were embarking on their tour of Yosemite Valley.

The state of the art tractors, purchased by DNC Parks and Resorts at Yosemite, at a cost of $150,000 each, pull trailers for the two-hour tour narrated by a National Park Ranger. The tractors and engines were manufactured by the International Harvester Corporation and the hybrid drives were manufactured by the Eaton Corporation. The new vehicles which operate on a combination of electric and diesel power replaced propane powered vehicles used to pull the trailers.

The new tractors will reduce emissions by 85 % and get 800 % better fuel economy than the previous vehicles. This addition complements a fleet of 16 Yosemite National Park hybrid shuttle buses used in the Yosemite Valley. Over 70,000 Yosemite National Park visitors take the tour Yosemite Valley Floor each year.
