Remove tree stump with hi-lift jack.
White pines approx 20-30 feet tall. Cut down in the fall and waited till spring to allow roots to die off. Also waited for spring rains to soften up ground. The combination made light work.
This is just a video posted to help if you have a similar situation. Would prob not work as good for larger trees but worked great for tree trunks up to 10 inch in diameter. Again best to cut tree and let’s roots die before using high lift.
Hopefully this idea helps u.
