Buckets play an important role in mini excavator operations. No matter what scale project you are working on, the right bucket can make everything different in the quality and pace of your work.

Imagine that: If you own a Chinese mini excavator, how will you attach a bucket to it?

Learn how to attach a bucket to a mini excavator, enhancing your machine’s functionality for various projects.

Key Takeaways

1. Essential Tools: Wrench or socket set, bucket pin removal tool.

2. Step-by-Step Process: Position excavator, prepare quick coupler, align bucket, secure attachment, and test.

3. Maintenance: Regular inspection and servicing ensure long-term performance and safety.

Essential tools

Wrench or Socket Set: The wrench or socket set is fundamental for operators. They help you loosen and tighten the bolts securing the bucket to the excavator. Make its size and type fit the bolts on your mini excavator model.

Bucket Pin Removal Tool: This tool is indispensable. It is designed to fit snugly over the pins and remove them without causing damage. Also, choose a tool that is compatible with the size and type of pins in your mini excavator’s bucket attachment system.

You can start changing a mini excavator bucket once you have prepared essential tools.

Attaching a bucket to a mini excavator

Step 1: Position the Mini Excavator

Park the mini excavator on a level surface because a stable foundation ensures that the machine doesn’t shift or move during the attachment.

Engage the parking brake and lock the machine in place. With the parking brake firmly engaged, you can proceed with the attachment process with ease. The mini excavator won’t budge until you’re ready to work.

Next is to turn off the engine to reduce the risk of accidental activation. By turning the engine off, you can focus on the task at hand without distractions or hazards.

Step 2: Locate and Prepare the Quick Coupler

You should be careful in this step since it impacts the efficiency and safety of the attachment process.

Once the mini excavator is securely positioned, the next step is to locate and prepare the quick coupler.

Inspect the mechanism that consists of two main parts: the coupler plate on the excavator and the corresponding attachment ears on the bucket.

Keep the quick coupler unlocking by operating a release lever or pressing a button.

When unlocked, the coupler should allow for the free movement of the attachment pins used to make the bucket in place.

With the quick coupler ready and waiting, you can proceed to the next steps.

Step 3: Align the Bucket

Put the bucket correctly in front of the mini excavator.

Carefully slide the bucket into position, ensuring that the attachment ears — the points on the bucket to connect with the quick coupler — are facing the corresponding hooks on the coupler.

This alignment ensures a secure fit and prevents misalignment. If they were misaligned, this would compromise the stability of the attachment or lead to operational issues.

Take your time during this step, it may require slight adjustments to the position of the mini excavator or the bucket itself to achieve the perfect alignment.

Step 4: Secure the Bucket

Now it is time to secure the attachment.

Any misalignment in step 3 could lead to an unstable connection. To secure the bucket, you’ll need to lower the mini excavator’s boom.

Slowly operate the excavator’s controls to lower the boom. As the boom descends, the bucket’s attachment ears should slide smoothly onto the quick coupler’s hooks.

Ensure that the weight of the bucket doesn’t cause any sudden shifts or jerks that could damage the equipment.

Once the bucket is hooked onto the quick coupler, final adjustments are here for a proper connection.

Check that the bucket is sitting squarely on the coupler, without wobble or sway.

If necessary, you can make minor tweaks to the position of the excavator or the bucket to ensure a snug fit.

You can slightly move the excavator’s arm or nudge the bucket to settle it in place.

When the bucket is correctly seated, double-check the quick coupler’s locking mechanism. If your quick coupler has a locking pin or similar device, make sure it’s securely in place to prevent the bucket from disengaging during operation.

Step 5: Test the Attachment

It’s necessary to confirm that the attachment is not only safe but also ready for the job ahead.

To begin testing, you’ll need to lift the bucket, using the mini excavator’s controls to raise the boom and the bucket off the ground.

As the bucket ascends, observe the bucket for any signs of movement or instability.

A properly attached bucket should remain steady. At the same time, listen for any unusual sounds that might indicate a problem with the attachment.

You should only hear the normal operational noises of the mini excavator.

Any metallic clanging or grinding could show that the bucket is not properly secured or the quick coupler is not functioning as it should.

Remember to address any issue as soon as possible. Lower the bucket back to the ground and re-inspect the attachment.

Ensure that the quick coupler is fully engaged and the locking mechanism is fixed.

If the problem persists, you can ask for professional assistance.

Double-Checking and Operating

Before operating the mini excavator, you should closely check again.

Pay close attention to the quick coupler. You should ensure that the locking mechanism is fully engaged and the bucket is firmly seated.

After double-checking, finally, you can start the engine and disengage the parking brake.

But remember to check the bucket’s movement before working. Operate the mini excavator’s controls to raise and lower the boom, observing the bucket’s response. Check for smooth motion and listen for unusual noises.


Regular maintenance is a must if you own a mini excavator. It determines how long your machine can go. That’s why you need to set a maintenance plan.

Firstly, inspect the bucket for any signs of wear and tear, such as cracks, dents, or sharp edges.

Pay more attention to the cutting edges, as these are subject to the most stress during digging.

If the bucket’s teeth are worn out, it may be time to replace or sharpen them for the best performance.

Following your maintenance plan and giving regular inspections will make your machine always in good condition.


Learning the way to attach a bucket to a mini excavator enables you to do all of these steps on your own. By doing so, you can gain the joy of having a mini excavator and operate it with pride.


Q: How do you attach a bucket to a mini excavator?

A: To attach a bucket to a mini excavator, position the excavator, prepare the quick coupler, align the bucket, secure it by lowering the boom, and test the attachment for stability and proper function.

Q: What attachments can you put on a mini excavator?

A: Some of the common attachments for a mini excavator include buckets, augers, hammers and breakers, grapples, trenchers, rippers, palisade installers, mulching heads, etc.

Q: Can you put steel tracks on a mini excavator?

Yes, you can equip a mini excavator with steel tracks. Installing steel tracks involves ensuring compatibility with the mini excavator’s undercarriage system.

Q: Can you use ratchet straps for a mini excavator?

The use of ratchet straps must be cautious for mini excavators.

In some scenarios, ratchet straps might be used to secure accessories or attachments to the mini excavator during transport.

If you are moving a bucket not permanently fixed to the machine, ratchet straps can help keep it stable and prevent it from shifting or falling off during travel.

It’s noted that ratchet straps should never be used to lift a mini excavator or to support its weight.
