There are dozens of options for excavator attachments. Some are pretty straightforward, but others are more open-ended and could be used in various ways. Depending on your industry, you might have particular needs for an attachment.

You’ll also find that attachments can go by many names, which change based on region and job site.

So here are some standard excavator attachments, what we call them, and how we’ve seen them used.

Check out this overview of hydraulic couplers:

Types of Couplers for Excavators

Mechanical Couplers: Mechanical couplers are manually operated and use pins or latches to secure the attachment to the excavator. The operator manually inserts the pins or engages the latches to lock the attachment in place. The operator must manually disengage the pins or latches to release the attachment. Based on the size of the machine, it can take more than one person to disengage the pins. If it’s an especially large machine, a sledgehammer might be involved to get the pin out. So on larger machines, we’d suggested a hydraulic coupler to make things more efficient.

Hydraulic Couplers: Hydraulic couplers use hydraulic cylinders to connect and disconnect attachments from the excavator. The operator can control the coupler from the cab, engaging or disengaging the attachment without leaving the operator's seat.

Advantages of Using Excavators Couplers

The bucket's profile allows it to move quickly and shape larger volumes of soil, making it particularly useful for tasks that involve creating or maintaining drainage systems, channels, and similar linear excavations.

Skeleton or Grapple Bucket: Skeleton or grapple buckets have openings or spaces between the tines, allowing fine materials like soil to fall through while retaining larger debris like rocks and logs. There are different types of grapples (i.e. root, rock, rake, etc.) depending on what you need it for.

Tilt Bucket: Tilt buckets have a tilting mechanism that allows the bucket to tilt left and right, providing enhanced flexibility for shaping slopes, grading, and ditch cleaning. You’ll find them with a straight edge.

Padding or Screening Bucket: These sort and separate materials on-site, allowing the operator to retain valuable material while removing debris and unwanted particles during excavation and material handling tasks.

Trapezoid bucket: A trapezoid bucket gets its name from its unique trapezoidal shape. These buckets dig and grade materials while maximizing the bucket's capacity. The sloping sides of the bucket allow for better material retention and smoother cutting through the ground during excavation tasks. These are sometimes called V-shaped buckets or V-ditch buckets and used in ditching, trenching, and pipeline work.
