Check the horsepower ratings of the TSC stuff. Last I knew, most of it was rated for 30 hp or so. Many years ago, I started out with a TSC scraper blade. I was a frequent customer at the local weld shop. Then I bouht a Woods blade and it hasn't broken in the tens years I've had it.
Now that I have more appropriate equipment (Woods, Bush Hog), if I hit something that doesn't want to move, the tractor tires slip until I hit the clutch.
