Ordering a new excavator bucket doesn't need to be complicated. Whether you're replacing a worn bucket or expanding your attachment range, taking a few simple measurements before ordering helps ensure your new bucket fits correctly the first time.
At Mammoth Attachments, one of the most common questions we receive is "What measurements do you need?". Fortunately, there are only three key dimensions that are normally required, along with your excavator details.

Why Measuring Your Excavator Matters
Many people assume that knowing their excavator make and model is enough to order a replacement bucket. Whilst this can often point you in the right direction, it doesn't always guarantee compatibility.
Manufacturers occasionally alter linkage dimensions between model years, and many excavators are fitted with aftermarket mechanical or hydraulic quick hitches. Even machines within the same weight class can require different pickup dimensions.
Taking a few accurate measurements before ordering helps avoid delays, returns and the frustration of receiving a bucket that doesn't fit.
The Three Measurements You Need
1. Pin Diameter
The pin diameter is simply the diameter of the mounting pins that pass through the bucket ears.
The easiest method is to remove a pin and measure it using vernier calipers. If this isn't possible, measuring the internal diameter of the bucket holes will usually provide the same information.
Always measure in millimetres rather than estimating.
2. Pin Centres
Pin centres are measured from the centre of one pin to the centre of the other.
This is arguably the most important measurement because even a small difference can prevent the bucket fitting correctly.
Be careful not to measure edge-to-edge, as this is one of the most common mistakes made when ordering a replacement bucket.
3. Dipper Gap (Bucket Ear Width)
The dipper gap is the internal width between the bucket ears where the excavator arm or quick hitch sits.
This measurement needs to match your excavator linkage or hitch exactly to allow the bucket to fit correctly without excessive movement.
Other Information That Helps
Alongside the three key measurements above, it's useful to provide:
- Excavator make
- Excavator model
- Machine operating weight
- Whether a quick hitch is fitted
- Quick hitch manufacturer (if known)
- Photographs of your existing bucket
Photos are often enough for us to spot anything unusual before you place your order.
Measure the Existing Bucket Where Possible
If your current bucket fits correctly, it normally provides the easiest reference.
By measuring the bucket already attached to your excavator, you know you're working from dimensions that are proven to fit your machine.
If the bucket has significant wear around the pin holes, mention this when ordering so measurements can be checked accordingly.
Choosing the Correct Bucket for Your Machine Size
Once you've confirmed the attachment dimensions, the next step is selecting a bucket designed for your excavator's operating weight.
1–2 Tonne Excavators
Mini diggers are commonly used for landscaping, drainage and domestic groundwork. Our 1–2 Tonne Excavator Digging Bucket is available in widths from 150mm to 750mm, making it suitable for everything from narrow service trenches to general excavation.
2–3.5 Tonne Excavators
This popular machine class suits a wide range of groundwork applications. Browse our 2–3.5 Tonne Excavator Digging Buckets to compare available widths.
4–6 Tonne Excavators
For larger landscaping, construction and site work, our 4–6 Tonne Excavator Digging Bucket range offers widths from 230mm through to 900mm.
Common Measuring Mistakes
- Measuring edge-to-edge instead of centre-to-centre.
- Guessing the pin diameter rather than measuring it.
- Not mentioning an aftermarket quick hitch.
- Only providing the excavator weight.
- Mixing inches and millimetres.
- Assuming every excavator in the same weight class uses identical linkage dimensions.
Do I Need to Measure if I Know My Excavator Model?
Sometimes yes, sometimes no.
If your machine is completely standard, the make and model may be enough for us to identify the correct bucket.
However, because many excavators have aftermarket hitches or specification changes throughout production, providing measurements removes any uncertainty and gives confidence that the bucket will fit first time.
Can Mammoth Help?
Absolutely.
If you're unsure about any of the measurements, simply send us:
- Your excavator make and model
- Pin diameter
- Pin centres
- Dipper gap
- Photos of your existing bucket or quick hitch
We'll help confirm the correct bucket before you order.
Frequently Asked Questions
Can I measure the bucket instead of the excavator?
Yes. If the bucket currently fits your machine correctly, measuring it is often the easiest method.
Do quick hitches change the measurements?
Yes. Mechanical and hydraulic quick hitches can alter the pickup dimensions, which is why it's important to tell us if one is fitted.
What if I only know my excavator model?
Contact us with the make and model first. In many cases we can advise immediately, but we may ask for measurements to confirm compatibility.
Can you identify the correct bucket from photos?
Photos are extremely helpful and often allow us to verify measurements or identify the type of hitch fitted to your excavator.
