Hi Jens
What a horrible position you find yourself in. Poor hedgehog – very sad. Of course, we don’t know for sure, but garden machinery can cause terrible injuries to hedgehogs.
I also wondered, like Annker, whether you could find a veterinary surgeon who would do what is necessary for the hedgehog. Here, I believe, most vets will treat wild animals free (and there is a wide network of hedgehog carers/rehabilitators) but I don’t know what the position is in Sweden. As Annker suggests, it might be worth trying to ask a vet – that’s what I would do. They would know how to deal with the hedgehog in the most humane way.
