An excavator is a powerful tool. Youll find it on a wide variety of construction sites, landscaping projects and demolition areas. Typically, it allows for powerful digging into the ground, clearing the way for whatever youre working on. With the help of attachments, however, your excavator can become any number of additional tools, like a jackhammer, a clamp, a mower and more.
Attachments can open up a new world for your excavator, allowing you to do more with a single machine. You can save money and improve efficiency at the same time. You can find many of these options available as both standard and compact excavator attachments. Keep reading to learn about the different types of excavator work tools you can use and which attachments might be best for your mini excavator.
The types of excavator attachments available genuinely run the gamut. You can find attachments for compact excavators, crawler excavators and more. Nearly all of them offer quick-attach mounting hardware, so you can swap tools as needed. Here are some of the best excavator attachments for a wide variety of jobs.
Augers are excavator digger attachments that help you penetrate deep into the ground. They have a spiral design that transports the dug soil out of the hole as it goes. They are common on residential projects and are often used for drilling holes for pillars and planting trees and shrubbery.
There are many different options for augers, as they are a versatile tool. You can find mounting brackets that include single-pin hitch, double-pin hitch or a double-pin cradle hitch. These let you swap out attachments quickly. You can also find different power options, such as direct-drive and gear-driven augers. Direct-drive augers provide better balance and speed, but gear-driven is best for applications that require a lot of torque.
Buckets are usually constructed from hard steel and feature teeth on the digging edge to help with penetration, though lightweight buckets might lack teeth. Heavy-duty buckets might need tungsten teeth to get through tougher materials. You can find different types of excavator buckets, such as:
If you need to break up a large swath of material, like stone or a slab of concrete, you can turn to the hammer attachment. It may also be called a breaker or hammer-breaker and works like a big jackhammer, using high impact to break up the material. Youll have a few options in terms of hammer shape, and selecting the best one depends on the characteristics of the material youre working with. Some of the different types of hammer attachments include the following:
A hammer attachment can vary in size, depending on your scale and what youre breaking.
Some landscaping operations are too much for a regular mower, and thats where the flail mower comes in. You can angle it like a hedge trimmer and use it to cut more challenging objects like tall grass and shrubs. The flails bounce off of permanent objects, like rocks or the side of a road. This feature gives them an advantage over traditional mowers, which often throw rocks and other items they encounter during operation.
In many areas, throwing materials is a safety hazard or can cause damage to other structures. Another area where traditional mowers fall behind flail mowers is in upkeep a flail mower offers simpler maintenance because sharpening or replacing the individual cutters is easier than replacing an entire blade. For excavators and mini excavators, brush cutter attachments can also make your tool more versatile and valuable.
Instead of a dedicated grader, you can use a grading attachment to level out the ground. A grading blade or bucket for mini excavators helps prepare a flat surface for different projects. You can adjust the angle of the blade and its height to get the right level of surface grade. You can find grading blades in an array of different sizes and for various terrains and machines. This tool can also be called a grading bucket attachment for mini excavators and standard excavators.
A grapple is one of the more common excavator attachments for forestry work, but you can also find it in demolition, construction, waste handling and more. It uses two large, curved clamps to grab onto materials, often oddly shaped or irregular. One kind of grapple allows you to move both sides, while the other can only move one side. For either type, the grapple is usually controlled by hydraulics, which allows you to adjust the angle and rotation of the tool.
A ripper is a straightforward-shaped tool with a pointed end that enables you to rip through the hard ground or frozen surfaces with powerful force. It can help you rip up earth and scarify it, as well as remove embedded items like stumps and root systems.

The thumb is a large clamp that can hold materials in place in a bucket. It presses down on the content inside the bucket to make it stay in place. Many use it for gripping irregularly shaped materials that dont typically fit, such as demolition debris or tree stumps. It is a common excavator attachment for demolition, but it is also popular in other applications.
Mulchers are mini excavator forestry attachments used for environmental cleanup and managing plant life at a job site, among other things. These attachments cut vegetation, undergrowth or other plant materials and turn them into mulch. With the teeth inside the drum, mulchers can trim anything from the undergrowth to small trees. Mulching comes with the dual benefit of eliminating unwanted plant growth and generating useful, biodegradable material that can be used elsewhere on the site or sold for profit.
When you need to clear brush or other debris at a job site, a rake attachment can help you do so quickly and easily. A beneficial feature of the Cat rake tools is that their three-, four- and five-tine shapes collect debris and leave the dirt behind. Whether youre clearing brush, tree branches or anything else, these rakes help you save time and increase efficiency. Both tine-only and grapple rakes are available to outfit your mini excavator for various forestry applications.
Understanding what tools will work best for your application is just the start you need a way to switch between them easily.

Choosing an excavator for your job is only the first step in acquiring the tools you need. Whether theyre mini or large, excavators are incredibly versatile because of the available bucket and attachment options. Given the many types of backhoe and excavator buckets on the market, a lot of factors contribute to finding the right bucket for the job.
From understanding excavator bucket dimensions to learning about the different excavator bucket types, this guide will teach you how to choose the right excavator bucket for your needs.
When choosing an excavator bucket, the first thing to consider is the specific application and type of material you are handling. You typically want to find the biggest bucket for your job, taking into account the material density and the size of the hauler truck.
Remember the weight of the bucket limits your cycle time, and the bucket only becomes heavier when loaded with heavy materials. As a general rule, use a small excavator bucket for higher-density materials to avoid slowed productivity. You want to be able to load your hauler truck quickly with as few cycles as possible to reduce fuel consumption, wear, and downtime.
Different applications can also require specific types of buckets. For example, you wouldnt be able to dig an 18-inch trench with a 30-inch bucket. Some buckets have features to handle certain types of materials. A rock bucket has a V-shaped cutting edge, and long, sharp teeth that can break through hard rock and push heavy loads with more power. A digging bucket is known to handle hard soil. Consider the type and density of your material and ensure you select a bucket that is capable of lifting it.

An excavator can do anything from digging trenches and laying pipes, to landscaping and moving snow. Several bucket types enable an excavator to handle various materials within these applications. While there are also many specialty buckets available, the five most popular buckets include:
A general-purpose bucket has the most versatility and is appropriate for many excavating tasks. It is also known as a digging bucket, and it is the standard attachment that comes with an excavator. If you rent an excavator without specifying a bucket, youll probably receive a general-purpose bucket. It comes with short, blunt teeth that work great on soil and are available in many sizes for various applications.
Here are some of the materials you can move with an all-purpose excavator bucket:
You can also find wear-protection components to allow an all-purpose excavator to work with more abrasive materials.
Grading buckets stand out for their smooth edges, wide construction, and flat cutting edges. They also have lift eyes, weld-on side cutters, and reversible bolt-on cutting edges. This construction creates smooth edges for all digging areas and works best with soft materials and soils. Grading buckets, also called clean-up or ditching buckets, have a lot of versatility for loading material, grading, leveling, back-filling, sloping, and cleaning ditches for improved drainage.
When you know how to use a grading bucket, you can use it for many applications, including:
A heavy-duty or severe-duty bucket is usually made from high-strength, abrasion-resistant steel. Because of their superior durability, these attachments are often used in rock quarries to load trucks with high-density material in fewer passes.
Cat® excavator buckets come in general-, heavy-, severe-, and extreme-duty varieties. They provide enhanced digging for heavy or abrasive materials, such as:
Severe- and extreme-duty buckets can handle even heavier materials, including:
Like a grading bucket, a trenching bucket is used for trench digging. It works well for narrow cable trenches, pipe culverts, and drains. It has a narrow shape, a sharp, flat blade, and an extended front section for better access. This tool can dig deep trenches while maintaining a fast cycle time. A trenching bucket should be used for high-precision jobs, such as digging around pipes.
This narrow bucket looks almost claw-like and is used to dig deep trenches that are only a few inches wide. It can save contractors a significant amount of time in backfilling and digging. It can also be known as a fiber-optic bucket because it is useful for creating trenches for laying fiber-optic cables, irrigation systems, and pipes.
An angle tilt bucket has many of the same applications as a grading bucket with the added feature of 45-degree rotation in either direction. Because of the tilting ability, these buckets are useful for creating precise slopes. They also allow an excavator to move or shape more land without changing positions as frequently. These features may allow you to experience increased uptime with heavy-duty construction.
Angle tilt buckets come in many sizes for a variety of applications, such as:
A tilt ditch cleaning bucket does exactly what its name suggests. This specialized cleaning bucket shares a similar design to a grading bucket. It can tilt at a 45-degree angle to allow the operator to work at difficult angles. Many consider this a finishing bucket used at the end of a project for tidying and creating smooth finishes.
Visually, a skeleton bucket closely resembles a digging bucket. However, there is a major difference between the two. A skeleton bucket has large slots that work like a grid on its back. This is used to let fine materials filter through it, leaving behind larger materials.
The skeleton bucket is a versatile tool that does two things at once. It works as a usual excavation bucket that simultaneously separates stones, concrete, and trash from useful or building materials.
Utility buckets are incredibly useful tools when excavating near pipelines and cables. When cables are struck, it can harm the excavation crew and affect the system they are connected to. With a utility bucket, a crew can work without worrying about the risks of striking cables.
The bucket is double-enforced by using rounded edges rather than teeth, improving structural integrity. This bucket type is best suited for working near gas lines, water and sewerage pipes, and underground cables.
Besides the most commonly used buckets, you can find a variety of specialty bucket designs to use for specific jobs:
With so many types of excavator buckets, its a good idea to consider renting one when you need to accomplish a particular task. If you plan to use the bucket for many jobs, you can save money by buying a used excavator bucket. If choosing a previously owned or rented bucket, you need to understand how to inspect for damage or repairs. Look for the following elements:
Most construction projects benefit from a bucket that will increase productivity by reducing the number of passes the tool needs to make. Select the biggest excavator bucket that wont compromise efficiency except when you have a particular size requirement, like when digging a trench.
Remember that the bucket you use on a 20-ton excavator would be far too big for an 8-ton excavator. A bucket thats too big will require the machine to do more work, and each cycle will take longer, reduce efficiency, or cause the excavator to topple over.
Generally, a range of bucket sizes will work for the excavator you have. Mini excavator bucket sizes can range from specialty 6-inch buckets to 36-inch buckets. Keep in mind that some sizes only apply to grading buckets, and you shouldnt use other types of buckets with those dimensions.
To see what size of bucket is possible for the weight of your excavator, use this excavator bucket size chart:
Each jobs bucket capacity depends on the size of your bucket and the material you are handling. Bucket capacity combines the material fill factor and density, the hourly production requirement, and cycle time. You can calculate your buckets capacity for a particular project in five steps:
To tool your excavator bucket for whatever applications you have in store, you can customize the bucket with many add-on features:
The best time to replace the teeth is before they wear down entirely and expose the bucket adapter. To fit the bucket with new teeth, follow these nine steps:
