As Dan says below, stick to the heavy 557 chain. If it is made in the U.S. or Japan it is probably O.K. If from else where, be wary. You get what you pay for. Cheers.
Oops! should have added that we had terrible results with non Agco grain elevator chains. They lasted a season! Replacement Agco chain is still going strong. 1994 R62 in cereals and lentils. Some dust and dirt with the lentils. Cheers.
