Over 10,000 pounds you're supposed to have 4 chains and 4 binders. So you could use 4 really short chains. Like you said it is under 10,000 pounds skid steer only. Its a good chain down! I dont think they would bother you. That's something you could certainly do differently is the 4 short chains and 4 binders. Thats a federal dot requirement like you stated. The chain over the brush hog is excellent!! Any loader, excuvator etc needs either a chain or strap over the top of the bucket/ attachment, boom or other item. The chain over the loader attachment (brushhog) could easily keep you from getting stopped. Nice work
