What can be damaged when operating in articulation mode?

Operating a road grader in articulation mode can place significant stress on the rear tires, making them susceptible to damage. Articulation involves the grader's ability to bend at a pivot point, allowing greater maneuverability. However, this maneuverability also means that the rear tires have to navigate turns and changes in direction that can lead to increased wear and potential damage.

In articulation mode, the weight distribution and the angle of the tires change. If the rear tires are subjected to excessive lateral forces or sharp turns while in this mode, they can experience scrubbing, which can cause sidewall damage or uneven tread wear. This is particularly a concern on uneven or rough terrain where the tires may not make consistent contact with the surface.

Though other components like front tires, side panels, or blade edges can also experience wear and tear during operation, they do not face the same specific risks associated with the articulation movement that predominantly affects the rear tires. Thus, understanding the dynamics of articulation in road grader operation highlights why the rear tires are especially at risk for damage.
