That saw looks mighty sketchy
Has a sliding table that you can kind of see in the picture below. I've got one that flips up on my H Farmall
There was a little girl out near my grandparents that was killed 30-40 years ago by one, helping her dad cut firewood. He looked away and she got too close, it sucked her scarf in and pulled her head in. I think everyone in the county has heard the story because I heard about two dozen different people at the auction say that's the kind of saw that got Leland's daughter.
It's not something that I use too often, just think it looks neat mounted on the tractor. My chainsaws are much more convenient.
I also came home with a hand-operated drag saw, something I have never seen before...
