When you're sizing up an excavator-mounted vegetation-cutting attachment, the choice between a disc hedge trimmer and a reciprocating hedge cutter really comes down to three things: how they cut, what you're cutting, and the finish you're after. Both hook up to the excavator boom and run off the auxilia...

When it comes to hard rock excavation, you're usually looking at two main approaches: a hydraulic breaker that pounds the rock with impact energy, or a drill-and-splitter setup that uses controlled mechanical force. Both will break rock, but they work on completely different principles and deliver very differen...

Picking the right excavator rock drill and splitter comes down to matching the attachment to three things: the rock you're working in, the excavator's hydraulic and lifting muscle, and the project's needs for fracture control, production rate, and site restrictions. A unit that's undersized for the ...

An excavator rock drill and splitter knocks out two jobs that used to take two separate machines: it drills a precise hole into the rock, then uses that same hole to ｉｎｓｅｒｔ a hydraulic wedge and fracture the material along a controlled line. Since both functions are mounted on the same excavator boom, one operator ...

The boom is the large, hinged arm section that ties the excavator's upper structure to the dipper arm. It's the first and longest segment in the excavator's working linkage, and it handles the up-and-down motion of the entire front attachment. Every digging, lifting, and material-handling move starts wi...

The excavator arm is the section that sits between the boom and the bucket, and it's the part that controls the in-and-out motion of the attachment during digging and lifting. While the boom handles the up-and-down movement, the arm reaches out to the work face and pulls back to drag the bucket through the mate...

Operators and equipment buyers often throw around the terms boom, arm, and stick like they're interchangeable, but they actually refer to distinct sections of the excavator's front linkage. Each piece has its own mounting point, hydraulic control, and specific job in the digging cycle. Knowing the differenc...

Excavator booms come in more flavors than the standard mono boom most operators are used to seeing every day. Each design changes the machine's working envelope, lift capacity, and breakout force to fit a specific job. Picking the right boom type has a direct impact on productivity, safety, and costs—whether yo...

Getting familiar with the parts of an excavator boom pays off when it's time to troubleshoot, perform maintenance, or order replacement components. The boom is a welded steel fabrication with several distinct structural and mechanical sections, each designed to handle specific loads during the digging and lifti...

The excavator arm isn't a one-size-fits-all proposition. Different lengths and designs change the machine's working envelope, digging force, lift capacity, and maintenance demands. Choosing the right arm for the job directly impacts productivity and operating costs—because an arm that's too long cuts in...
