 Crawler Dozers

Crawler dozers are powerful tracked machines that use a variety of front mounted blades to move material. Large dozers often do pioneering work, such as moving dirt in preparation for new roadways or removing overburden in mining applications. Smaller machines often are used as grading tractors, sometimes using automated grade controls to precisely establish complex contours.
