Nowadays, most small, medium, and large dozers have both standard and LGP options because of how important it is on so many sites. It's also important to note that there is a range for both operating weight and blade width depending on the different tracks, cabs, or blade attachments a dozer may have. Blade width signifies how efficient a dozer can be while blade capacity, measured in cubic yards, refers to how much it can push, depending on the blade.īoth blade width and capacity are directly proportional to both the operating weight and horsepower of the machine, as well as the blade type. Horsepower gives a good understanding of the pushing force a dozer will have. Operating weight is an estimate of how much the machine will weigh once the operator, cab, and fuel have been considered. The most important specs are typically operating weight, horsepower, blade width, and whether the dozer has low-ground-pressure (LGP) functionality.
