A digging bucket<\/a> and a grading bucket<\/a> look similar from the cab, but they answer opposite problems. The digging bucket concentrates machine force into a narrow cutting edge to break ground; the grading bucket spreads the same machine over a wide floor to finish it. Most excavator fleets carry one of each and swap them on the quick coupler<\/a> several times a day.<\/p>\n\n\n\n

The two KaiVoy ranges side by side<\/h2>\n\n\n\n

Coupler codes follow the attachment, not the machine – the same rule used across all KaiVoy excavator attachments<\/a>. S30-180 covers compact carriers, S40 the 3.5 – 6 t class, S45 the 8 t class.<\/p>\n\n\n\n
