When it comes to fitting excavator buckets and attachments, many operators wonder if there is a universal standard that applies to all machines. This guide will address the common question of whether excavator buckets are universal and provide a detailed explanation of how to determine the right bucket for your specific digger. By understanding the intricacies of bucket fitments and the essential measurements required, you can ensure that you select the correct equipment for your excavator, optimising performance and efficiency on the job site.

In short; no, excavator buckets are not universal. However, there are times where machine fitments are often crossed over, so buckets that fit on one excavator will also work on other excavators. For example, a standard JCB 801 bucket, will fit on a standard Kubota KX36 machine, or a Bobcat X335 will also fit a Volvo ECR58 machine. To complicate matters further, when you start to look at larger excavators, such as 12 ton and 20 ton machines, they are often fitted with a hydraulic quick couplers which feature a travelling latch. This means that the buckets that can be used on this machine are almost always universal, as the hydraulic hitch will pick up the slack between the pin dimensions of different sized buckets.
To determine which buckets and attachments fit your excavator, you need to know the pin dimensions of your machine. Specifically, you must measure three dimensions: Pin Diameter, Pin Centres, and Dipper Gap. For this, you will need an excavator bucket or attachment that you know fits your machine, along with a tape measure or ruler. We recommend using a measuring device that can measure in millimetres (mm) for greater accuracy. When purchasing buckets, attachments, or hitches from a manufacturer, these pin dimensions will be requested to determine the precise model that will fit your mini digger or excavator. If you don't have an attachment available, follow the steps in the video below to learn how to measure your excavator without any buckets.
Measuring the pin diameter is straightforward. Take one of the pins you currently use to attach your digger bucket and measure its widest part. The easiest way to do this is with a set of vernier callipers, but you can also use a tape measure or ruler. Alternatively, you can measure the inside of the hole on the hanger. Keep in mind that if the bucket is well-used, there may be a few millimetres of wear.
The dipper gap is the internal measurement between the bucket hangers, where the main arm of the digger and your bucket link fit. Measure the smallest internal size, usually found between the bosses. The easiest way to do this is with a tape measure or ruler. You can also measure the outside width of the bucket link, but this method can be less accurate due to wear, so use it only if absolutely necessary.
The final measurement you need is the pin centres, which is the distance between the centres of the two bucket pins. The easiest way to measure this is with a ruler or tape measure. Instead of estimating the centre of the pins, measure from the front edge of one pin to the front edge of the other pin.
If you would like to purchase a bucket or attachment to match your dimensions, please get in touch with us or search for the correct attachments based on your measurements. By providing accurate pin dimensions, you can ensure a perfect fit and enhance the efficiency of your excavator.
Choosing an excavator for your job is only the first step in acquiring the tools you need. Whether they&#;re 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 wouldn&#;t 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, you&#;ll 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, it&#;s 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 won&#;t 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 that&#;s 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 shouldn&#;t 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 job&#;s 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 bucket&#;s 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:
