This 'might' work if you remove the bumper first to keep it from being damaged before pushing/bumping on the impact absorber. Pushing on a round object might also bend the impact absorber's plate if you're not square on the tree. Use a tape measure to see and know when enough pushing is enough push. The back tires will need to get traction so the tree needs to be close to the driveway or road. (not reliable for damage of property or person(s) using the above procedure...use at your own risk...your mileage my vary...battery not included)
