whats up everybody?
I have heard alot about tier on equipments, such as komatsu , and cat and so on, and i've heard about tier 3 and tier 4.
My question is whats the difference between them, I know when the companies talk about tier it is pertaining to emissions but I want to know what sets tier 3 apart from tier 4?
And as well as Tier 1 and Tier 2, if there are such things :confused:
