Mackenzie’s “G175 Tree Crusher” cleared over 2500 acres of forest in preparation for the flooding of Williston Reservoir in the mid-1960s.

The G175 Tree Crusher, manufactured by LeTourneau, was built specifically for land clearing. It is the only self-powered tree-crushing machine of its size. It works in the same way as a steamroller and is powered by electricity.

The unit arrived at Kennedy Siding on six flat rail cars in 1964. It took four days to unload and reassemble. An effort was made to bring the computer across the country to the work area from November 21 to December 9, 1964.
