Other modifications to the original bulldozer include making it smaller to let it operate in small work areas where movement is limited such as in mining.
Over the years bulldozers got bigger and more powerful in response to the demand for equipment suited for ever larger earthworks. Firms like Caterpillar Komatsu Case Euclid5 Allis Chalmers Liebherr LiuGong Terex Fiat-Allis John Deere BEML XGMA and International Harvester manufactured large tracked-type earthmoving machines. R.G. LeTourneau and Caterpillar manufactured large rubber tired bulldozers.
By the 1920s tracked vehicles became common particularly the Caterpillar 60. Rubber-tired vehicles came into use in the 1940s. To dig canals raise earth dams and do other earth-moving jobs these tractors were equipped with a large thick metal plate in front. (The blade got its curved shape later). In some early models the driver sat on top in the open without a cabin. There are three main types of bulldozer blades: a U-blade for pushing and carrying dirt relatively long distances a straight blade for "knocking down" and spreading piles of dirt and a brush rake for removing brush and roots. These attachments (home-built or built by small equipment manufacturers of attachments for wheeled and crawler tractors and trucks) appeared by 1929.
