I'm pretty sure the saw cutting roofing slates operation, that OSHA would not approve! Also, I couldn't help but notice that the belt looks like it's about to come off the saw pulley and the tractor pulley as well, and I'm pretty sure that OSHA would not approve of that either! I also noticed that some of these multi bottom plows are not really plowing but just barley scraping the surface! Nice steam traction engine, saw and video. Thanks for sharing it with us!
