![]() Dozer blades are used in combat to eliminate ground obstacles and prepare fire positions. This blade is commonly used to push huge rock stacks, such as at a mine.īulldozer blades are mounted on military engineering units and can be added to other units, such as artillery vehicles like the Type 73 or M8 Tractor, for the purpose of combat. ![]() An "S-U" hybrid blade with shorter side flaps is less curved. A Universal Blade (or "U-Blade") is a long, curved blade with big side flaps that can hold more substance. The bulldozer blade on a vehicle's front end is typical of three types.Ī Straight Blade ("S-Blade") is a delicate blade that is small and it has no horizontal bend or side flaps. The dozer blade is a hefty metal sheet mounted on the front of the vehicle for moving things, navigating hard terrain, and pushing sand, dirt, and trash. So, first came the bulldozer blade.Īlthough it is unknown who developed the first bulldozer, the dozer blade was in use long before any tractor was built. During 1913-14, Hornsby sold their rights to Benjamin Holt. The Hornsby model, on the other hand, was closer to today's bulldozers in that it was directed by modulating power to every track rather than having a steering wheel in front of the tracks like Holt's machines. None of these inventions was a bulldozer instead, they were track-laying traction motors. Based on a patent awarded to their head engineer, the Hornsby firm of England modified one of its wheel steaming traction engines to a tracklayer (crawler) type at about the same period. Benjamin Holt constructed infinite chain traction for his steam traction engine around the end of 1904, according to experts.
