If you’ve tried to clear a wooded lot in Cloquet and hit a wall of glacial boulders two feet down, you already know the problem. This isn’t southern Minnesota farmland. The Cloquet soil series sits on top of dense, rocky glacial outwash left behind by the old Superior Lobe — and standard clearing equipment doesn’t last long against it.
Tollefson Excavating runs heavy-duty forestry mulchers with high-durability teeth engineered specifically for Northern Minnesota conditions. We cut through thick stands of jack pine, paper birch, and quaking aspen without fracturing on the hidden rock below. What’s left behind isn’t a muddy, eroded mess — it’s a layer of shredded wood chips that binds to that stony surface, locks in soil, and actually protects the ground during freeze-thaw cycles.
For homeowners and developers working in Carlton County, that matters. Brush clearing and forestry mulching done right means your site is stable before the first shovel of foundation work begins. We’ve worked this terrain long enough to know where the boulders hide, how deep the root balls run, and what it takes to leave a clean, buildable lot behind.
EXCELLENT Based on 30 reviews Posted on Google Becky PembertonTrustindex verifies that the original source of the review is Google. We had some driveway work done and are so happy with the result! Connor returned calls quickly, came out and got us a quote and did the work as soon as road restrictions lifted!! We were out of town when he did the work and he sent us pictures of the progress! He even fixed a walkway issue without adding any cost! Highly recommend Tollefson excavating! Pleasure to work with!!Posted on Google Kayla LarsonTrustindex verifies that the original source of the review is Google. Couldn’t be happier with their work! Professional, timely, and amazing quality of work. Highly recommend!!Posted on Google John HanceTrustindex verifies that the original source of the review is Google. Love the personal service Conner provides!Posted on Google Isaiah JohnsonTrustindex verifies that the original source of the review is Google. We had Conner come out to our property to help us complete our hay field restoration project. Conner went above and beyond what was expected. We appreciated his clear communication and vision for what we needed done. We will be using Conner for our future projects and would highly recommend him.Posted on Google Molly JohnsonTrustindex verifies that the original source of the review is Google. Connor is great at what he does! He was professional, fast, and did the job perfectly. Great communication and high-quality work. Would definitely hire them again.Posted on Google Michelle MowryTrustindex verifies that the original source of the review is Google. I hired Tollefson to excavate my garage site (on a hill in Duluth) and remove three tree stumps from site. He did a great job, was easy to communicate with, came out an extra time and fixed an error made when marking site (not his error - contractor error), and made sure my back-fill happened before freeze up! He even seeded and put straw over when he was done.Posted on Google Rakel JohnsonTrustindex verifies that the original source of the review is Google. We hired Tollefson Excavating to dig out our existing pond, which had become overgrown and was turning into an eyesore. Conner completely revitalized it, and the results far exceeded our expectations! The pond looks so much cleaner now, and our family is excited to be able to use it. His skill with an excavator really showed, and he did quality work from start to finish. Overall, we had a great experience working with Conner and would highly recommend Tollefson Excavating to anyone looking for dirt work at a fair price.Posted on Google David JonesTrustindex verifies that the original source of the review is Google. My wife and I felt comfortable right away after meeting Conner at our new home construction site. Not only did he do a fantastic job with site clearing, excavating and grading our new home site, Conner was there at our site the day he said he would be there. That was huge. I will highly recommend Conner to anyone looking for a reliable excavator.
From residential projects to commercial developments, we provide end-to-end solutions for every stage of construction.
We don’t show up and start cutting. Every job starts with a walk of the property to mark legal boundary lines, identify protected trees, and flag any subsurface concerns — including the glacial rock and boulder deposits that catch inexperienced operators off guard in this region.
From there, the work moves in a logical sequence:
First, we clear the invasive brush and understory. Dense buckthorn, tag alder, and heavy undergrowth come out before we ever touch a standing tree. This gives our operators clean sight lines and a safer working environment.
Next, we fell larger timber in controlled drops. Each tree comes down with the surrounding landscape in mind. Stumps are extracted with a root rake that’s built to work in gravelly, boulder-heavy subsurface — not tear up the topsoil layer you’ll need later.
Finally, the site is mulched, graded, and left ready for the next phase. Whether that’s a residential lot clearing and stump removal project or a larger commercial development, the ground we hand back to you is even, stable, and clear of debris. No burn piles. No hauled stumps unless that’s specifically what the project calls for. Just a clean slate.
A family purchased a heavily wooded 2-acre parcel along the St. Louis River corridor. The site required Carlton County land disturbance permits and strict MPCA stormwater controls before a single tree could come down. Tollefson installed perimeter silt fencing, cleared dense aspen and birch, grubbed the root systems from rocky glacial till, and left a mulched, stabilized building pad — all within the shoreland setback requirements.
A utility contractor needed rapid right-of-way site preparation along a half-mile stretch near Minnesota State Highway 33. Tollefson mobilized tub grinding and forestry mulching equipment via MN-33 and completed the initial rough clearing and utility easement creation on schedule, keeping the adjacent ground stable and the corridor clear for the contractor’s follow-on crew.
Take a look at some of our latest work. Scroll through the photos below to see our team in action and the results we deliver.
Yes. Any land-disturbing activity over one acre near the St. Louis River watershed typically requires an MPCA NPDES/SDS Construction Stormwater permit and a written SWPPP plan. Carlton County may also require its own land disturbance review. We help you understand what applies to your specific parcel before work begins.
Yes. Our mulchers run carbide-tipped, high-durability teeth rated for exactly this kind of terrain — heavy Northern timber over shallow glacial rock and outwash. We don’t run standard ag-spec equipment on Carlton County ground.
For most Cloquet-area projects, on-site forestry mulching is the better call. Burn piles require DNR burn permits, dry weather windows that don’t always come in a Minnesota winter, and leave you with bare, frost-vulnerable soil. Mulching converts the timber into erosion control right where it stands.
Carlton County Shoreland Management rules establish setback buffers — typically a minimum of 50 feet from the ordinary high water mark, though this varies by lake or river classification. Vegetation removal within the buffer zone is restricted. We work within these setbacks and can help you understand what Carlton County has on file for your specific parcel.
We sort them on-site. Boulders that can be used for erosion control, drainage management, or landscape grading stay on your property if you want them. Those that can’t be repurposed are staged for haul-off. Either way, they don’t get left buried where they’ll cause problems for your foundation or utility trenches later.
