Askov sits on sandy glacial soils under dense jack pine and aspen — and that combination creates two clearing problems that catch operators off guard.
First: sandy soils freeze deeper than clay because they hold less moisture. Pine County’s frost season is long, and the sandy upland sites around Askov freeze further down than lowland sites. Stump extraction on frozen sandy ground puts more demand on equipment and operators than the same job on clay terrain in a different county.
Second: once the tree cover comes off, that same sandy soil erodes fast. Bare sandy ground in Pine County doesn’t wait for the next heavy rain to start moving. Operators who clear and leave exposed sandy soil behind create a stabilization problem that costs more to fix than it would have cost to address during the job.
Wooded parcels along the I-35 and MN-23 corridor near Askov are actively being cleared for residential builds and rural development. Grindstone Lake and the Kettle River corridor generate consistent cabin-build clearing demand — selective clearing within Minnesota DNR shoreline setback requirements on properties where what stays matters as much as what comes down.
Tollefson Excavating clears Askov-area land for what the soil and the season actually require.

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![]()

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![]()

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![]()

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![]()

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.
No equipment moves on an Askov clearing job until we’ve walked the site.
We assess soil condition, frost depth timing, timber density, access routes, and any DNR shoreline setback requirements for lake or river-adjacent properties. For cabin builds near Grindstone Lake or the Kettle River corridor, we identify which trees are staying before anything comes down — selective clearing on these sites requires a precise plan, not a general approximation.
Tree and brush removal is sequenced to protect the soil and any vegetation being preserved. Stumps are ground or extracted based on the site’s intended use — building pads need stumps out, recreational lots may only need grinding.
Debris is handled before we leave — hauled off, chipped on site, or managed based on your preference and the site conditions.
Erosion control on Askov’s sandy soils is not optional. Bare sandy ground moves fast in Pine County. We stabilize exposed soil before leaving the site — seeding, erosion blankets, or matting depending on slope and conditions. Fixing erosion after the fact costs more than preventing it during the job.
Cleared ground ready for what comes next.
An Askov-area landowner with a wooded parcel off MN-23 needed full lot clearing for a residential build. Sandy soil and late-season frost conditions required careful stump extraction timing. We walked the site, cleared all trees and brush, extracted stumps to building pad depth, chipped debris on site, and stabilized the exposed sandy soil before leaving. Owner had a build-ready lot with no erosion issues through spring thaw.
A Grindstone Lake property owner needed selective clearing for a cabin build — specific trees removed for the building pad and lake view, others preserved for screening within DNR setback requirements. We walked the site with the owner, marked every preserve tree, and cleared precisely to the plan. Stumps ground on the pad, erosion control applied to disturbed sandy soil. Cabin contractor had a clean, compliant clearing on arrival.

Yes. Sandy soils freeze deeper than clay because they hold less moisture. Stump extraction on frozen sandy Pine County ground is more demanding — we assess frost conditions before scheduling below-grade work.
Yes. We walk the site, identify DNR setback boundaries, mark preserve trees, and clear precisely to the plan. Only what needs to come down comes down.
Yes — it moves fast once exposed. We stabilize bare sandy ground before leaving every Askov clearing job — seeding, erosion blankets, or matting depending on slope and conditions.
Yes — both included. Stumps ground or extracted based on site use. Debris hauled off or chipped on site. Nothing left behind.
Yes. We work throughout Askov, the Grindstone Lake area, Kettle River corridor, and surrounding Pine County — wooded lots, cabin sites, and residential parcels along I-35 and MN-23.
