You must be joking. When was the last time you used a 66" blade in the middle of a metal refinary with temps. over 120 degrees wearing steel toed boots, pants and long sleeves. Not simply for a few hours or days, but try weeks and months. You dont quit/slow down cutting concrete in the winter. Try having you carharts completely frozen with a 1/2" layer of ice all day long while you are continuously sprayed with slurry. Most guy sdont finish concrete by themselves. Cutting concrete you are almost always by yourself. You unload you whole truck on a daily basis, and if you need something, to bad your truck is not right at the work area since its not deemed necessary and it is to large so you must hoof it back to the truck for every little thing you were hoping you wouldnt need. Finishing concrete is pretty cut and dry sure there are issues that arise, but rare is is in the middle of a job is there the possibility that your hanging off the side of a sky scraper downtown, cutting through 480volt electric daily, cutting through wires that shut down everybank for 4 states, dropping through floors with a 1500lb road saw because noone saw a tunnel under where you are cutting, leaving for 8 month stays out of town on less than a days notice, drilling 66" holes in the side of a damn and hoping they are right when they gauged the pressure build up behind it, being called out at night for gas leaks and having the 4 trucks of firefighter staring at you holding hoses because there is a real possibility your not making it out alive. And that was just day 1.
