bulldozer

Janet Bennet-Evans was the only woman to drive a crawler tractor in the Welsh Region of the Ministry of Supply (Tree Production). Many women worked in the forestry industry, some of them as wood measurers, stacking planks for drying, equipment maintenance, measuring cut wood, measuring and crosscutting poles for props, stripping bark and branches and loading wagons. They also did general work, pruning, felling and planting trees.

The giant TD-24 was the new flagship for International’s crawler line. It weighed about 20 tons (with dozer blade) and was powered by a new 180 hp (130 kW) 1091ci 6-cylinder diesel. The transmission and steering design was unique. The main transmission was a 4-speed synchromesh (for on-the-go shifting), and it had a separate forward and reverse unit for fast cycling in dozer work. There were also power-shifted 2-speed planetary gears in each track that made up the Planet Power Steering system. The planetary gears were controlled by the steering levers. Combining the high and low range of the planetary gears with the main transmission provided a total of 8 forward (and 8 reverse) speeds. Putting one track in high range and one in low caused a gentle turn with power to both tracks. For sharper turns, the pivot brakes disconnected the inside track, as with a normal crawler.
