Last winter I found some rocks I didn't want to see using a snow thrower and the end result was they smashed my snow blower drive chain . I could buy a replacement from the dealer for $50 or have it made with Koch parts. I decided to take the last option. Since then I have had no more problems with my drive chain and still have spares should the need arise. This chain is very strong, comes pre-lubricated and is very consistent. I didn't see any burrs or machining marks either. I'm impressed with the quality.
