Seem to be sturdy enough. We're only picking up things limited to our little tractors capacity so these will be plenty strong enough. Main concern is no weep holes. Water intrudes then can't get out. Will be a problem in winter. I'll drill some holes to allow the water to escape and hopefully keep them from freezing and swelling or busting. Second problem is how the chain slots are oriented. If you use a chain, you can't use a 2x4 in the upright slot and on the bottom, they cause the chain to drag along the ground. Which will use you from leveling the forks if on a hard or concrete surface. Overall though they are sturdy and easy enough to put on your bucket. No instructions are included so just use trial and error until you're happy with how you decided to install them!
