This technical report covers the development of an icedozer attachment for removal of ice obstructions and rough grading of uneven ice surfaces. The unit consists of a self-powered, rotating, spiked-tooth cutter mounted on the front of a size 3 crawler tractor. Tests near McMurdo Station, Antarctica, during the summer season of Deep Freeze 66 showed that the icedozer was suitable for rough grading uneven ice surfaces and for producing ice-aggregate fill for roads and runways on ice. The tests also showed that the unit was not entirely suitable for finish grading and surfacing operational areas on ice. The icedozer is considered suitable for pioneer construction and rough grading ice obstacles and uneven ice surfaces, but an iceplane-grader employing the icedozer attachment should be developed for finish grading and surfacing roads and runways on ice.
