Can an excavator remove tree stumps?

If you're asking the question 'can an excavator remove tree stumps?', you might also be wondering, 'what size excavator do you need to remove tree stumps?' or 'will a mini excavator remove tree stumps?'. The simple answer is... yes - you can remove tree stumps or similar objects with an excavator. The best way to remove a tree stump, and the safest method, is using an excavator ripper tooth. This excavator attachment is the best tree stump removal tool as it's designed with a narrow end point to help maximise the force while digging. The pointed design helps to penetrate through the hard material around the stump (like solid mud or clay) and acts as a leaver to wedge under the stump and roots to dislodge them.

Removing Tree Stumps with an Excavator

The size of the excavator you can use to remove a tree stump will depend on multiple factors, including the size of the tree stump, the depth of the roots, the conditions of the ground material and the amount of space surrounding the area you are working. To remove the tree stump you will have to begin by digging a trench around the circumference of the stump so that the roots can be accessed and removed.

1. Small Tree Stump Removal - Less than 6 Inches

If you are trying to remove a small tree stump from your garden, a mini excavator will be sufficient! A mini excavator is a machine between 1.5 to 6 tons (3,000 lbs to 12,000 lbs) that can handle 1 to 20 tons (2,000 to 40,000 lbs) of weight, whether that be dirt, aggregates or even bark. Mini excavators are the most popular size of machine for DIY projects or smaller landscaping or construction jobs. A ripper tooth will be extremely effective with this machine size to remove a small tree stump, as they can easily dig up the roots and dig around the stump to dislodge it from the ground.

2. Medium Tree Stump Removal - 6 to 16 Inches

If you are trying to remove a moderately sized stump, a mini excavator should still be an appropriate sized machine for the job, although we would recommend an excavator 3 tons (6,000 lbs) and above to be most efficient. This size range of machine will be able to remove more substantial roots. A ripper tooth would be a beneficial attachment for a medium sized tree stump as it will concentrate the power of the excavator into one area, helping to unearth the stump, as well as other objects that you might want to remove like large boulders or old pipes.

3. Large Tree Stump Removal - Greater than 16 Inches

If you are trying to remove a large stump, a medium-sized would be more appropriate. Midi excavators range between 6 to 10 tons (12,000 to 20,000 lbs and can handle 20 to 50 tons (40,000 to 100,000 lbs) of weight! This size machine will be best used for moderately sized tree stumps with more substantial roots that will need more power to help extract. Excavators this size are also most commonly used for demolition projects, commercial construction and landscaping projects and moderate excavation projects like ponds or small lakes. A standard 6 to 10 ton excavator will be essential if you are trying to remove a larger stump, like you would typically find in a woodland. These trees will have roots that will be much thicker, heavy and deeper within the ground, meaning more power will need to be used to extract the stump. As previously mentioned, a ripper tooth can be an extremely helpful attachment for helping to dislodge and extract objects like these in the ground.

How To: Remove a Tree Stump

Step 1: Preparation and Safety

Before starting, evaluate the area around the stump for any obstacles, utilities, or structures that might interfere with the excavation process. Ensure that you and any assistants are wearing appropriate safety gear, including hard hats, gloves, safety boots and eye protection. Check the excavator and ripper tooth attachment for any signs of wear or damage, and ensure the equipment is in good working condition. Remove any debris, rocks or other obstacles from around the stump to provide a clear working area. Position the excavator so you have a clear view of the stump and ample room to manoeuvre, ensuring the excavator is on stable, level ground.

Step 2: Dig a Trench around the Tree Stump

For larger tree stumps, dig a one-meter wide trench around the stump, adjusting the width accordingly for smaller trees as they have less extensive root systems. Dig the trench 2 to 3 feet deep to help detach the majority of the surrounding roots that run level with the ground. Remove as much of the underneath of the stump as possible to help detach the underneath roots; smaller trees will have more fragile roots, making them easier to remove. If the ground is too solid or the roots are too durable and embedded, use the ripper tooth to penetrate the solid ground, preventing damage to the bucket or bucket teeth and assist in ripping out stubborn roots.

Step 3: Loosen & Remove the Stump

To help loosen the roots from underneath the tree stump, push and pull the stump from different directions using your excavator - this movement will help break any remaining attached roots. If the stump does not come free, use your bucket or ripper tooth to continue removing soil and roots from under the stump to further loosen it. Continue the process of pushing and pulling, and digging underneath the stump until it begins to move. Once there is some movement, position your excavator boom over the top of the stump, reach your attachment under the stump, and use it to pull and lift upwards or towards you to remove the stump from the ground.

Step 4: Post-Removal Clean-up

To remove the remaining roots, if the stump comes out in multiple pieces, go back and repeat steps 2 and 3. Use your bucket or ripper tooth to churn up the soil, loosening any remaining roots, which can then be easily removed by hand or with the excavator bucket. Next, inspect the area to ensure it is safe and clear of debris, checking for any utilities or structures that may have been disturbed during the process. Fill the hole left by the stump removal with soil, compacting it to prevent future settling. Finally, dispose of the stump and roots by transporting them to a designated disposal area or processing them for mulch or firewood, if applicable.
