used heavy equipment

The first bulldozers were adapted from farm Holt tractors that were used to plough fields. Their versatility in soft ground for logging and road building, lead directly to them becoming the armoured tank in the first war. EquipmentPlacecom. By the 1920s, tracked vehicles became common, particularly the Caterpillar 60. To dig canals, raise earth dams, and do other earthmoving jobs, these tractors were equipped with a large thick metal plate in front. This thick metal plate (it got its curved shape later) is called a "blade". The blade peels layers of soil and pushes it forward as the tractor advances. Several specialised blades have been developed: for high volume loads such as coal, rakes to remove only larger boulders, or blades with razor sharp edges to cut tree stumps.
