Absolutely fantastic. I've even hit a few nails with it and it's had no ill effect on the blade. Still as sharp as ever and back pain is a thing of the past. Last week I added a new toy to the collection too - a Hycrack log splitter.
The little tractor really does struggle with that but hey ho, it's better than swinging a maul and when I do get a mog I'll have more than enough power to run it.
