A box blade is a type of implement used on tractors for smoothing and contouring land. It is almost always unpowered, though can have auxiliary hydraulics attached in order for adjustments to be made without leaving the seat of the tractor. It is attached to the tractor via the three point hitch.
The scraper can transport its load to the fill area where the blade is raised, the back panel of the hopper, or the ejector, is hydraulically pushed forward and the load tumbles out. Then the empty scraper returns to the cut site and repeats the cycle.
The M9 grew out of the universal engineer tractor (UET), a follow-up to 1958's all-purpose ballastable crawler (ABC), also a tractor. [4] By making a small tractor or scraper, it was possible to create a lightweight vehicle that could use local material as ballast.
The Fresno scraper is a machine pulled by horses used for constructing canals and ditches in sandy soil. The design of the Fresno scraper forms the basis of most modern earthmoving scrapers , having the ability to scrape and move a quantity of soil, and also to discharge it at a controlled depth, thus quadrupling the volume which could be ...
A grader, also commonly referred to as a road grader, motor grader, or simply blade, is a form of heavy equipment with a long blade used to create a flat surface during grading. Although the earliest models were towed behind horses, and later tractors , most modern graders are self-propelled and thus technically "motor graders".

A loader is a heavy equipment machine used in construction to move or load materials such as soil, rock, sand, demolition debris, etc. into or onto another type of machinery (such as a dump truck, conveyor belt, feed-hopper, or railroad car).
A "S-U" combination blade is shorter, has less curvature, and has smaller side wings. This blade is typically used for pushing piles of large rocks, such as at a quarry. Like many other bulldozers, the D9 can be fitted with other devices, such as mine plows. The rear ripper is intended for use in loosening rocky ground and ripping out larger ...
The advantages to this system is due to the accuracy that can be achieved with GPS and RTK, but requires an onsite base station. These systems can use either one or two GPS receivers and are mounted on the machine's blade. The more advanced systems use two receivers since it allows the machine to be controlled in a three-dimensional design.
